What Is an Air Compressor?

This machine uses power from engines like electric or diesel and then stores it in compressed air. It achieves this by employing various methods to force air into a storage tank, thereby increasing its pressure.

The air compressor automatically shuts off once the tank’s pressure reaches its predetermined maximum level. The compressed air remains stored in the tank until it is needed for a specific purpose.

This stored energy in the compressed air can be utilized in various applications by harnessing the kinetic energy released as the air is released and the tank’s pressure decreases.

When the tank’s pressure drops to a designated minimum level, the air compressor activates again and re-pressurizes the tank.

How Does an Air Compressor Work?

Air compressors operate by pressurizing atmospheric air, which is stored in a tank to harness potential energy for future use.

When the compressed air is intentionally released, similar to releasing air from an inflated balloon, the pressure is released, transforming the potential energy into useful kinetic energy.

This energy transfer can be utilized to power various pneumatic tools. Industrial air compressors function like combustion engines, and their operation typically involves a pump cylinder, piston, and crankshaft to facilitate energy transfer for a wide range of tasks.

These fundamental components enable air supply for tasks such as inflating tires or inflatable pool toys and powering tools like drills, nail guns, grinders, sanders, and spray guns.

From impact wrenches to air conditioning units, many versatile air-powered tools and machines contribute to our everyday comforts, shelter, automation, and efficiency.

Air compressors are designed to be compact, lightweight, and portable compared to other centralized power sources. They also exhibit durability, require less maintenance, and offer greater mobility than traditional machinery.

How Much CFM Do I Need for Spray Painting?

The cubic feet per minute requirements of paint guns vary depending on the model. Smaller spray guns typically require a lower CFM compared to more extensive options.

While certain air spray guns have a rating of less than 10 CFM, your compressor should have a minimum CFM of 12 for spray painting.

Professionals may need an even higher CFM, but the key is to ensure that you have checked the CFM requirements of your spray gun and selected a compressor that surpasses that value.

Spray Painting with an Air Compressor

What You Need

Hose.

Spray gun attachments: filter, regulator, quick disconnect fittings.
