What is cfm air

The more continuous use of air pressure a tool requires, the greater the tank size needed. Tank sizes range from 1 gallon to 80 gallons, but a single power tool may only need a maximum 5 gallon tank. Another thing to consider is how many tools will be connected to the tank at once. Fittings are necessary to connect the air hose to the compressor, and come in two variations.

FPT, which stands for female pipe thread, has an internal threading. MPT, or male pipe thread, has external threading instead. For an example of each type of thread, see the image above.

The two fittings on the right have an MPT. Those on the left are FPT. Industrial air compressors use a diesel engine to draw in air, compress it, and release it in a powerful flow. Air is pulled into a chamber and compressed by two rotary screws, and then released from a nozzle at the other end. This air can be used to power several pneumatic machines at once, including paving breakers, chipping hammers, clay diggers, rivet busters, sandblasters, and rock splitters.

PSI refers to the force of the air your machine can put out measured in pounds. On the other hand, CFM refers to the total volume of the air your compressor can release measured in square feet. With pneumatic machines, the higher the PSI, the harder your attachment will drive. The greater the CFM, the faster it will work. For example, your pneumatic nail gun might be able to deliver nails at PSI of force, but if your CFM is too low, it might only build up enough force to deliver one nail a minute.

Attachments will generally come with information on their CFM requirements. Another easy way to calculate your CFM is by using an airflow meter. This will give you the amount of flow and the pressure that is coming out of a fitting. Flow meters can be installed on individual pieces of equipment or complete systems to provide an instant reading of actual usage.

For a more accurate reading, a receiver tank should be installed near the flow meter to even out peaks and valleys in the data. There are different types of flow meters that can be used for point-of-use measuring, and in-line measuring.

VIP Instruments has a vast array of different flow meters. If you are in a very low or very high elevation area, you could have a different PSIA. No need for any follow-up. Compressed Air is critical to my operation. I would like to discuss the challenges with my system.
