How To Use A Spray Gun With Air Compressor

For spray gun, you’ll need an air compressor with a CFM rating of at least 2-6 and a PSI rating around 15-20. HP should be in the 2-3 range, and the tank size should be around 6 gallons or higher.

What Is A Spray Gun?

A spray gun is a type of tool used to coat surfaces with paint, varnish, lacquer, or other material. It makes use of compressed air which helps it to atomize the coating into small particles that then form a thin layer on the surface. Some spray guns come with adjustable settings for air pressure and volume control.

What Are Different Types Of Spray Guns:

Different types of spray guns are designed for different purposes. Some are designed for general purpose spraying, while others are designed for specific applications. The most common types of spray guns are:

1- Airless Paint Sprayer

2- HVLP Paint Sprayer

3- Airbrush

3- Spray Can

1. Airless Paint Sprayer: This type of spray gun uses high pressure to force paint through the tip of the gun without the use of compressed air. Airless paint sprayers are ideal for large jobs, such as painting a house or a fence.

2. HVLP Paint Sprayer: This type of spray gun uses high volume, low pressure to spray paint. HVLP paint sprayers are ideal for smaller jobs, such as painting a piece of furniture.

3. Airbrush: An airbrush is a small, handheld spray gun that uses compressed air to atomize paint. Airbrushes are typically used for smaller jobs, such as painting models or touching up paint jobs.

4. Spray Can: A spray can is a handheld canister that contains paint or other liquid. Spray cans are typically used for small jobs, such as painting a picture frame or a vase.

What Is Air Compressor Spraying?

Air compressor spray painting is the process of using a spray gun to atomize coating material with compressed air. The air pressure and volume control settings on the spray gun help to create a thin, even layer of the material being sprayed. This method is ideal for painting cars, furniture, walls, or any other surface that requires a smooth finish.

What Size Air Compressor Do I Need To Run A Spray Gun?

The size of the air compressor you need to run a spray gun depends on the type of spray gun and the type of material you are spraying. Generally, for a standard gravity feed spray gun with an operating pressure range between 15-20 PSI, a 2-3 HP compressor is recommended. However, if you want to use an HVLP spray gun, you will need a larger compressor that can generate around 10-14 CFM at 90 PSI.

Recommended CFM & PSI Chart for different type of Spray Guns:

Gravity Feed HVLP Spray Gun – 10-14 CFM at 90 PSI:

Suction Feed HVLP Spray Gun – 7-10 CFM at 40 PSI

Conventional Airless Sprayer – 0.5-1.0 GPM at 3000 PSI

Air Assisted Airless Sprayer – 0.5-2.0 GPM at 3300 PSI

High Pressure Airless Sprayer – 1.0-3.0 GPM at 3900 PSI

Advantages Of Using A Paint Sprayer Air Compressor:

Using a paint sprayer air compressor has many advantages when it comes to painting projects. It is cheaper than using a brush and roller, while offering superior results in terms of even coating, sharp edges, and smooth finishes.

Additionally, with an air compressor you can use thicker paints that are not possible with rollers or brushes.

Finally, painting with an air compressor is much quicker than using traditional methods.

By understanding the process, taking small steps at first and then gradually increasing difficulty with practice, you can get great results quickly when spraying with a paint sprayer air compressor.

Disadvantages Of Using A Paint Sprayer Air Compressor:

Using a paint sprayer air compressor does have some disadvantages. It can be difficult to control the amount of paint that is sprayed and it is hard to achieve detailed work with a spray gun such as straight lines or intricate designs.
