Things to Consider Before Buying Air Compressor for Impact Wrench

Compressor size

This is an essential consideration that a buyer has to undertake before buying the air compressor for impact wrench. An air compressor is the power source. It is hard for any type of wrench to provide services when the air pressure is not enough. When purchasing a recommended air compressor for impact wrench, have a look at the air consumption.

The measurement of air consumption is usually in cubic feet per minute. For the wrench to operate fully, the air compressor should offer air at 90 PSI. If it is less than this, it means that the efficiency will be altered as the wrench will consume extra pressure than the compressor can provide.

Drive Size

The drive’s size is also a factor to look into when buying an air compressor for impact wrench. Bigger size drive shouldn’t always be considered to be the best as it has been mistaken by many. It is essential to spare enough time to look at the variety of bolts that you will be dealing with.

Discover the impact sockets in a specified size and know the size of the drive available in. Once this has been discovered, it will be easier to see the size of the drive suitable for the size of the socket you will be dealing with.

Horse Power (HP)

The best way to determine the compressor size for your needs is by looking at the HorsePower. It is essential to be keen on this factor because most air compressors are on the market just to sell. Some sellers or manufacturers have exaggerated the Horsepower so that they can sell them faster.

There is a lot of accuracy on industrial air compressors. To be on the safer side when doing this is to understand the electrical power required or it to run. The best 5 HP motor should be able to draw something close to 24 Amps on 220 V.

Cubic Feet per Minute (CFM)

For air tools to keep momentum with their efficiency, they need a particular amount of air volume. A compressor produces air, and its rating is in Cubic Feet per Minute (CFM). This is the reason why you will see compressors with different CFM ratings. You will also experience a higher rating for CFM displacement. This calculated rating is usually based on the speed and size of the compressor pump.

Smaller compressors have a CFM rating at 90 PSI, the recommended pressure that runs most tools. It is possible to get a CFM exaggeration, which is the same case with Horsepower. In most circumstances, it should be 3 to 4 CFM per HP at 90 PSI.

Air Pressure (PSI)

The rating of air pressure is usually in Pounds per Square Inch (PSI). Air tools require at least 90 PSI so that they can operate properly. For the device to be maintained at 90 PSI, a compressor that has a more significant shut-off pressure is necessary. Most of the industrial compressors fall in the two-stage category. They have two shut-off pressure stages, with the first at 90 PSI and the second to 175 PSI.

Smaller commercial duty is a single stage with the shut off being between 125 and 135 PSI. It is proper air pressure, but then they kick in is at around 100 PSI. With pressure resulting from hose and coupler restrictions, it isn’t sufficient pressure for a tool.

Size of the Air Compressor Tank

Even though the compressor tank isn’t behind the production of air, it plays the role of storing the air produced. You won’t run short of air if you have a bigger tank to store the air. The pump and motor should also be big enough such that even if the container is small, the air will still be available for the tool.

Frequently Asked Questions (FAQs)

1. How much air pressure do I need for my air compressor?

Answer: An Air compressor for impact gun is either powered by an electric or gas motor. A compressor that generates up to 90 PSI of air pressure is suitable for home use. However, if you want to use the compressor for more substantial tasks, we recommend 100-125 PSI. Contractors that require a more powerful machine or that plan to use various tools with the compressor should look for units with 125-150 PSI.

2. What size air compressor for impact wrench is needed?

Answer: The size of air compression needed for an impact wrench should be such that it can sustain a heavy workload. Since you can always halt your task for a refill, we recommend 5-gallon air tanks. If you plan to utilize the compressor for more great tools or continuous work, we recommend a bigger tank size.

3. How does an air compressor work?

Answer: The compressor operates by converting electrical energy into kinetic energy. It does this by drawing air from around the machine into the tank. It then pressurizes into an operating pressure. The converted pressure is stored in the container, and as you trigger the connected tool, the air rushed to the head. It is this pressurized air that is delivered to operate your impact wrench.

4. Do you recommend using a compressor with a generator?

Answer: Air compressor impact wrench combo is not unheard of. However, it is not always the best to use a compressor with a generator. This is because generators often cause power fluctuations to the compressor. As a result, it could considerably affect the performance of the compressor. Hence, we don’t recommend using a compressor with a generator. However, you should consult the product manual for more information about combining the machine with other power sources.

5. When should I change the air intake filter?

Answer: An air intake filter should be cleaned weekly for compressors that have this feature. Do note that it is only applicable if you use the compressor for about three days a week. You can also file for a change if you notice holes or wear in the filter.
