Best Air Compressor for Impact Gun

It is always a good practice to have a glimpse over the buying guide before you finally purchase a product. We’ll here try to provide the proper guidelines to make your work a lot easier. Let’s see the essential things that you should consider.

Power source

Generally, you may find two types of portable air compressors based on their power supply, and they are electric and gasoline.

For most indoor applicants, electric compressor is the best choice. The gas-powered compressor is used by the builders who use it for commercial purposes.

Airflow (CFM)

Different impact wrenches have different air flow requirement. Here is a list showing the most used impact wrenches and their CFM requirement-

Air tool Avg. CFM @ 90 PSI Avg. Operating PSI
Impact Wrench (3/8″) 3 90-100
Impact Wrench (1/2″) 4 90-100
Impact Wrench (1″) 10 90-100

Find your impact wrench requirements and then pick your compressor.

Maximum pressure

Greater PSI will allow you to run more powerful and multiple tools. It also directly interacts with the amount of air flow. So, you want to have as much PSI range as possible. You should at least have 125 PSI in your compressor for impact guns. Larger compressors should be in the region of 150-175 PSI.

Motor power

The power of a compressor mainly depends on motor power. For a consumer-grade machine, 0.5 HP is used. Compressors with 2 HP are powerful enough to run the motor for most of the impact tools.

Cord Length

You may guess that a long-corded machine is better than a short-corded one. Because, with a long cord, you can move the device wherever you need. Some air compressors have 10 feet cords, and some come with 15 feet. So, it is your decision which length is best for your work.

Tank Size and weight

Tank size is measured in Gallons. Most of the small-size portable compressors come with a 0-6 gallons size tank. Think about your project, and then choose the tank size. For domestic uses, the compressor with 0-3 gallons is enough. For professional uses, you need a larger tank.

On the other hand, weight depends on the size of the tank. A larger compressor can be more than 80 pounds. And the smallest size comes with 20 pounds of weight.

Oil-less or oil air compressor

Oil-less air compressors require low maintenance. Besides, it is contamination-free. On the other hand, oiled compressor provides larger output and its noise level is lower.

Noise level

Noise is always irritating. So, you should find out the air compressor that produces less noise. Usually, powerful compressors make more noises. Try to find out a compressor within 80 dB noise level.

Other considerable factors are warranty, brands, price, materials, durability, etc. So, before going to the market or ordering one online, you should do research remembering these matters.
