| Last Updated

A decent air compressor for spray painting provides you with the efficiency, unblemished finish, and even courage for your job. Equipment that you are going to use is probably the most important thing after your painting skills.

How to choose an air compressor for spray painting?

A piece of wrong equipment can lead to the problems of too lightly or heavy spray. It is good to choose wisely instead of facing such issues later. Many factors can help you choose the best air compressor for spray painting.

While purchasing the air compressor for spray painting, you need to make sure these things that I am going to list below.

Types of spray guns:

The first and foremost factor you need to consider while making the sale is the type of spray gun. You can use an air compressor with spray guns of two types, LVLP and HVLP. LVLP (Low Volume Low Pressure) spray gun consumes low air and you can use it with a normal air compressor as well. It is a great option for semi-professional jobs. It is cheap and comparatively less costly to use.

HVLP (High Volume Low Pressure) spray gun, on the other hand, works with a high volume of around 10-25 CFM and low pressure of less than 10 PSI. These spray guns are excellent for DIY and indoor jobs.

You can choose between both of them depending on your work requirements. HVLP is good for large-scale jobs while a VLVP spray gun can brilliantly paint the small things.

Air pressure:

Spray painting requires an air compressor with 10 to 30 PSI pressure. The pressure although varies in HVLP and LVLP spray guns. The air pressure usually lies between 25 to 30 PSI while the minimum air pressure could be around 10-15 PSI.

Before choosing an air compressor, make sure that it is compatible with the spray gun or other tool you are going to use.

CFM:

CFM (cubic feet per minute) of an air compressor is the amount of air produced by it in one minute. CFM plays a direct role in the air compressor and hence is the most important factor here. CFM is neither the force nor the pressure of air. It is the volume flow of air.

The air compressor you are going to purchase should have the capability to deliver the CFM which your spray gun requires. Otherwise, you will not be able to obtain efficient performance from it.

Tank size:

You cannot ignore the tank size of the air compressor. A spray gun requires a continuous supply of air to accomplish the painting job. The sporadic flow of air can interrupt the painting operation. Refilling also wastes a lot of time.

Experts recommend a compressor tank size of around 50 gallons. You can decide the tank size according to your requirements but it should not be less than 10 gallons.

Horsepower:

Another important thing on this list is Horsepower which is the rate at which work is done. An air compressor having motors with 1 to 2 horsepower is considered excellent for this kind of job. Remember that horsepower is as important as CFM and PSI (pounds per square inch). An air compressor with less than the required horsepower is nothing other than useless equipment.

Other factors:

Many other factors can help you in making the best decision for the selection of an air compressor for spray painting. You should always prefer a highly versatile air compressor over others as you will be able to use it in many other applications.

Budget can also be an important heading here. You should go with an air compressor which is comparatively inexpensive than others. Also, you should not compromise on quality.

Apart from them, a lightweight, small-sized, and less noisy air compressor will be fine for you otherwise you may face some issues while using it.

Conclusion:

Before going out for shopping, you should keep in mind these points I have mentioned above. In short, your target should be an air compressor that can not only accomplishes your work but also meets the requirements of the spray gun.

I hope my article will help you in choosing the air compressor for spray painting. I have tried my best to explain each and everything but still, if you think I have missed something then let me know. You can contact us for further queries.

What size compressor for blowing out sprinklers – step by step

| Last Updated

Blowing out the sprinklers is a must-do thing that needs to be done before the winter. Otherwise, water could stay in the pipelines and may turn to ice in the winter season which may lead to the cracking and damaging of underground pipes. Hence, it is better to winterize the sprinklers every year.

What size compressor for blowing out sprinklers?

There is no atomic science in blowing out sprinklers or winterization. You can easily do it yourself by following a few simple steps. But the question is what size compressor you need for blowing out sprinklers?

There are many types of air compressors available in the market. All of them are different because of their specific characteristics, properties, and features. You just need to choose an air compressor having these properties that I am going to list below.

Air volume:

Air volume is the amount of space occupied by the air. As per experts’ recommendation, the air volume of 20 to 25 cubic feet per minute is best to completely blow out sprinkles. It depends on the pipe diameter. You may require higher air volume when the pipe’s diameter is smaller than usual. The larger the pipe’s size is the lesser air volume it will need and vice versa.

Air pressure:

It is asked to avoid over-pressurizing during the whole procedure. Higher air pressure can blow off the heads and damage the irrigation system. The air pressure of 40 to 50 PSI (pound per square inch) is enough for winterizing.

Flow rate:

The flow rate of the air compressor is its ability to perform continuously for a specific time. After ensuring the air pressure and air volume of the air compressor, you will need to keep the flow rate longer than 2 minutes. In short, your air compressor should have the capability to deliver around 20 CFM for more than 2 minutes to get the job done.

Power options:

An air compressor can run on either gasoline or electricity. Electricity is comparatively cheap and easily available as you can connect the device directly to your house or job area. You will have to use a rubber nose instead of an extension cord to extend its reach as the extension cord can be riskier to use with an electrically powered compressor.

A gas-powered compressor, on the other hand, is only best when electricity is unavailable at the workplace. It is noisy, heavier in size, and costly as compared to the electric one. For a better experience, you should prioritize an electric air compressor over others.

Tank size:

The size of the tank also matters as an air compressor of small tank size requires you to refill it more often. Refilling takes a lot of time especially when you are working on a large scale with an air compressor that is taking 5 gallons to refill. If your working area is small then go with a normal size otherwise tank should occupy around 10 to 15 gallons.

FAQs:

Here are the answers to a few frequently asked questions about the above article.

Can I use my air compressor to blow out my sprinklers?

A home air compressor can only perform simple and small-scale tasks. When it comes to the job of blowing out sprinklers, only equipment of specified characteristics can perfectly do this. Although, you can winterize your sprinkler system by covering each zone separately.

How many PSI does it takes to blow out sprinkler lines?

As I have mentioned above that the air pressure of around 40 to 50 PSI is enough to completely blow out the sprinkler lines. The air pressure exceeding 50 PSI can damage the pipelines.

Is it necessary to blow out sprinkler systems?

Experts recommend blowing out sprinkler systems especially when the winter season is about to reach. The presence of water in sprinkler lines increases the risk of damage. The temperature of 4 degrees Celsius is too cool to use sprinklers. You should not use sprinklers at that time and water should be blow out.

Does the tank size impact the air volume?

There is no linkage between the tank size and air volume. So, it does not impact the air volume.

Conclusion:

This was my article explaining the compressor size for blowing out sprinklers. I have explained it in details. I hope this is going to help you winterize your irrigation system. I have tried my best but still, if you have any further queries, feel free to ask below in the comments. Have a nice day.

Benefits of Air compressors:-

1. They are Long-lasting:

All of the air tools like air compressors last longer than an ordinary electricity tool.

2. They are more powerful:

The air compressors work by producing highly pressurized air from the tank. This air can help you fulfill your needs.

3. Air compressors weigh less:

Most of the air compressors are portable and weigh much lesser than an ordinary device. You can easily move it around your house accordingly.

4. These compressors are less risky:

The air compressors are less hazardous as there is a low risk of fire or an electric shock due to the supply.

Sizes of air compressors:

Which-Size-Air-Compressor-Do-I-Need-for-Impact-Wrench

When it comes to the size, the air compressors come in different sizes from the larger ones that are needed in industries to the smaller ones used to fill the air in tires.

The size depends upon your needs and how do you want to operate the tool. For instance, if you are looking for an impact wrench, an adequate size is needed for the compressor to work.

Well, an air compressor is usually measured with the help of a unit, termed as PSI. The unit determines the air pressure inside the tank and its flow of air, which is measured with CFM.what size air compressor do i need for air tools

Now that you are cleared about the units, let me tell you that air pressure is extremely important for the air compressor to work. If one says that the higher the pressure, the higher the compressor’s output, then it will not be wrong. Just like it, the airflow is yet another factor to look for.

An impact wrench:

The size of an air compressor depends upon the size of your impact wrench. The larger is the size of your wrench, the more air you will need. So I will go through some sizes of the impact wrench and discuss the air compressors according to it.

1. ½ inch impact wrench:

This size is most common for an impact wrench, so finding the air compressor’s right size is extremely important. In this regard, you can choose any compressor that has a size of 5 CFM. Or you can either choose between 3.5 to 5 CFM.

2. 1-inch impact wrench:

A 1-inch wrench is not commonly used, except that they are used on higher levels. But if you have one, you can opt for an air compressor with 9 to 10 CFM.

3. 1/4th inch impact wrench:

The air pressure of this impact wrench isn’t that much. You can use an air compressor of at least 1.5 CFM for this size of the impact wrench. You can also choose a compressor that is higher than this.best size air compressor for home garage

4. 3/8th inch impact wrench:

Likewise, here you need a bit more pressure to do the job. A CFM of 3 or 3.5 works perfectly fine in this regard. Here, a 2.5 CFM air compressor can work, but I recommend opting for at least 3 CFM ones.

The air tank is yet another factor to consider. When you are going to look for an air compressor, you will see that the sizes are measured in gallons. So the larger size of the tank would be better. I will recommend you to go for a tank size measured 20 gallons or more than it. These air compressors last long so once you have bought one, you are free of worries. It will also help you work without any interruptions.

What is Air Compressor CFM? Calculate By Own

| Last Updated

Having to carry around huge machines from one place to another will probably tire you out before your work has even started. To avoid that problem, look for an air compressor today!

Being a versatile machine, an air compressor can be attached to various air tools. It acts as a power source and pressurizes air, turning it into mechanical energy.

If you have no idea how it works or what are the basics, for example, What is Air Compressor CFM?  Read this article, you’ll surely find all your answers.

What-is-Air-Compressor-CFM

What is an air compressor?

A compressor is a device that turns power into potential energy as compressed air. To state it simply, it forces air into a container and pressurizes it. Then the air is forced through an opening in the tank. The pressure builds up there. It works like a balloon deflating.

When mentioning a power tool, it usually has a power source attached to it. The power source adds to its weight. When you use an air compressor as the power tool, it is much lighter and easily portable.

This is why many industrial workers and manufacturers use an air compressor. And not only is it used in the industrial field but it is also used in home and garages too,

How does an air tool work?

Before working with anything, it is important to know what it does and how it works. Air tools are rising in the industrial world. They’re easy to use, portable, inexpensive, and even have a lower theft rate.

For all its advantages, you should buy one right now. And if you already have one, you might want some extra information that might come in handy. Here’s how an air tool works.

An air compressor compresses the air inside a tank. Attached to the air compressor is an air tool. It forces air through a hose that’s connected to the tool. Once it through the hose, a motor converts the pressure of the air into mechanical energy. The tool then starts working.

Different kinds of air compressors:

There isn’t just one type of air compressor out there. According to their capabilities and drawbacks, there are four different kinds of air compressors commonly used.

Rotatory screw compressors:

These are the easiest kind of air compressors to take care of. They are equipped with an internal cooling system and do not require much maintenance. These machines are quite large, used for industrial purposes. They can be run oil-free as well as with oil.

These work by trapping air between two rotors. The internal cooling system helps it to be used continuously. It ranges from 5 horsepower to 350 horsepower.

Reciprocating compressors:

Another popular type of compressor is the reciprocating compressor. It is used for much smaller jobs, like house-renovating. Unlike the rotatory compressor, a reciprocating compressor is not designed for continuous use. These work by a piston inside a cylinder, which compresses and displaces the air to build pressure.

These compressors have two types, namely; single-stage and multi-stage. Single-stage compressors perform smaller functions as they provide less pressure. Multi-stage ones provide more pressure for bigger jobs. They can reach up to 30 horsepower.

Axial compressors:

These air compressors are not found on construction sites. Instead, they are used in high-speed engines of planes and ships. Since they can provide thousands of horsepower, they have a higher efficiency rate. Also, they are quite costly. Because of these reasons, they are mainly kept for aerospace research.

Centrifugal compressors:

These compressors consist of a multi-phase compression process. Their primary function is to slow down the air. When slowed down, it becomes cool. Through this, potential energy is built up. These can produce a high amount of energy in a relatively small space.

They require the least amount of maintenance and can even produce oil-free air. The range of energy they provide is around 1000 horsepower. Which is why they are used in large construction like chemical plants and steel industries.

What-is-Air-Compressor-CFM

What are air compressors cfm?

The term cfm is short for cubic per minute. For all of you who don’t know what it is, well it is a measure of how much air is pushed out by a compressor. It shows the suitability of a compressor for a given application.

Machines like a saw or pressure washer require a much higher cfm. The reason behind this is that they are continuous demand tools. That is, they work without breaks. Hence, they require continuous energy.compressor cfm chart

While some machines require a lower cfm as they only need a sharp burst of energy. For example, a nail gun.

Cfm of various machines:

Different machines require different amounts of energy. To help you out, I have stated some of them below;

Impact wrench:

An impact wrench is a tool used to tighten or loosen a large nut, bolt, or frozen or rusted fastener. They provide high rotational torque.

A 1/2” wrench requires 5.0 cfm.

Air ratchet:

An air ratchet is used to tighten or loosen low to medium torque bolts. An impact wrench cannot be used on those as it may over-tighten or break them.

An air ratchet requires around 3 to 5 cfm.

Paint spray gun:

A paint spray gun is a tool that is used to spray a coating through the air on to the surface. The air directs the paint particles.

A paint spray gun requires 4-8 cfm.

Orbital sander:

An orbital sander is a disk machine used to smoothen down a surface. It is a mechanical device in place of sandpaper. The sanding blade delivers a random-orbital action on the surface.

An orbital sander requires 12 cfm.

Blowgun:

A blowgun is a tool used for light cleaning, drying, or blowing off parts. A nozzle is attached to one end that lets out pressurized air.

A blowgun requires 3 cfm.

Screwdriver:

You might probably be familiar with the manual version of this. A screwdriver is a pretty basic tool. It is used to tighten, loosen up or attach screws. The handle is attached to the air compressor.

A screwdriver requires 5 cfm.

Conclusion:-

In this article, I discussed everything about an air compressor. What an air compressor does, how air tools work, different types of air compressors, and what is air compressor cfm. I also mentioned some of the machines and how much cfm is required by them.

Throughout this article, I’m sure you found plenty of reasons why to consider buying an air compressor for your next big project.

How to paint a car with a small air compressor? | Step By Step Guide

| Last Updated

You can paint a car at home or an auto body painting with a small air compressor. You have to choose an Air Spray Gun and air compressor depending on the work. Although, it is possible to paint your vehicle with a small air compressor. But experts do not suggest it. Painting requires a continuous flow of air without any break. Hence, it is always recommended to use an air compressor with a large size tank.

Another issue with the small air compressor is that it takes a lot of time to refill and makes you feel irritated. Even the result will not be satisfactory. You will see rough strokes and an unsmooth surface. You can come over these issues by choosing an easy to refill or a bit large size air compressor.

Before discussing the step-to-step method for painting a car, let’s have a look at the type of air spray gun and air compressor you will need. Here we go!

Spray gun:

You will need a suitable air spray gun with attachments including a hose, filter regulator, and disconnect fittings etc. You also have to choose between the HVLP (high volume low pressure) and LVLP (low volume low pressure) spray guns.

Apart from these things, you will need a few other tools that I am listing below.

  • An air compressor
  • Safety kits: Goggles, gloves, mask, and clothes.
  • Paints (make sure to choose paints and solvents as per your requirements).
  • Covering, to cover the glasses and tyres while painting.
  • Cardboard

Parameters for air compressor:

  • Air Pressure

The first and the foremost considerable parameter in the selection of an air compressor for painting a car is its Air Pressure. The air compressor you are going to use must have the air pressure compatible with the spray gun and the task that you are going to accomplish. An air compressor with higher or lower PSI than that required by the tool may affect its efficiency.

I will not be wrong by saying that the selection of an air compressor depends entirely on the air spray. If you made the suitable choice for a spray gun, selecting an air compressor will be a piece of cake for you and vice versa.

  • CFM

CFM or cubic feet per minute is the amount of air in cubic feet produced by an air compressor in one minute. For car painting and other similar jobs, you will need an air compressor with comparatively higher CFM. Higher CFM is supposed to break the paint into many particles to ensure an even and smooth painting.
According to experts’ recommendations, a CFM of 15 to 20 is enough for tough jobs. But in the case of simple and minor tasks, you can go with the CFM of 5 to 10. In tasks like car paint, lower CFM results in uneven and rough painting.

  • Tank size

Here comes the most important factor in choosing the air compressor to paint a car. As I have discussed earlier that painting requires a continuous job otherwise it may cause the car surface to look dull. In order to improve the efficiency, all you need to do is choose an air compressor with a tank size of more than 50 gallons.

But as the title states “Small air compressor”, you can go with the tank size of 10 gallons. You can further compromise on the tank size if the vehicle is smaller in size otherwise 10 is just enough for this sort of job.

  • Horsepower

The horsepower of an air compressor is the rate of its work done. Horsepower rating defines the performance of the air compressor but this does not mean that higher horsepower can increase its performance. Most of the air compressors work efficiently with a horsepower of 1 and 2.

  • Power source

You can find electric-powered as well as gas-powered air compressors in the market. If you do not have proper access to electricity especially when you are working away from home or facing load shading, the gas-powered air compressor is excellent for you. Otherwise, electricity is cheap, easily available, and safe to use. Other than this, electricity has an advantage over gas in many ways.

How to paint a car with a small air compressor?

Here is the step by step procedure to paint a car with a small air compressor. Before starting, make sure that you have all the required tools.

  1. Wear safety gloves, goggles, and a face mask to protect your body. The paint contains some harmful chemicals that can damage your skin.
  2. Now, prepare the paint by mixing the paint, solvents, and other particles. Do not forget to maintain the specific ratio. Also do not mix old paint with the new one.
  3. Connect the spray gun with the air compressor using the hose. Make sure that the hose is tight and is not allowing any leakage.
  4. Before painting on the car, try it on any piece of cardboard etc. If it is giving the desired outcome then go ahead otherwise fix your sprayer.
  5. Start painting the car or its required surface. Cover the car windows and glasses.
  6. If you want to apply multiple coatings then wait until it dries. It may take 12 to 24 hours.

Conclusion:

This was my article about painting a car with a small air compressor. Owing the best sprayer will make it easy for you to choose the air compressor with the specification listed on it. Keep in mind that you can struggle with a small air compressor while painting a large vehicle.

I have tried my best to explain the procedure in detail. Keep all the factors (given above) in mind before purchasing the air compressor for car painting. If you have any further queries, feel free to contact us. Have a great day.
