The Importance of Using an Air Receiver Tank in a Compressed Air System

The Importance of Using an Air Receiver Tank in a Compressed Air System - Compressor and Receiver Tank - Parker Gas Separation and Filtration DivisionAn air receiver tank is an integral and important part of any compressed air system. Typically a receiver tank is sized at 6-10 times the flow rate of the system. So, if a compressor has a rating of 25 scfm at 100 psig, the receiver tank should be 150 cubic feet, minimum. In a compressed air system, a receiver tank provides the following benefits:

  1. The receiver tank acts as a reservoir of compressed air for peak demands.
  2. The receiver tank will help remove water from the system by allowing the air a chance to cool.
  3. The receiver tank minimizes pulsation in the system caused by a reciprocating compressor or a cyclic process downstream.

Much like a water reservoir provides water during times of drought and stores water during the wet times, an air receiver tank compensates for peak demand and helps balance the supply of the compressor with the demand of the system.

Receiver tanks are required by law to have a pressure relief valve and a pressure gauge. The relief valve should be set to 10% higher than the working pressure of the system.

It is also important to install either a manual or automatic drain on the receiver tank to remove water from the system. A coalescing filter and air dryer are best placed downstream of the receiver tank. Read more about drying compressed air.

Your recommendation is a little confusing:
"Typically a receiver tank is sized at 6-10 times the flow rate of the system."

The units: volume vs. flow rate don't agree, so there is some critical unit information missing with your sizing factor.

The next sentence muddies the issue further with the compressor rated at 25 standard (not actual) cubic feet per minute at 100 psi (~6.8x compression means ~3.67 acfm). The receiver is sized at 150 cubic feet, but is that volume or air storage in scf (actually ~22 ft^3 volume)? In other words, if you were to store air at 200 psi, would the receiver be half the size?

It seems that you would want to size the receiver to store a quantity air, depending on how much you would use on typical demand, as you would with a hydraulic accumulator.

Can you help me understand your recommendation?

Nice! In a compressed air system, the use of air receiver is really important. As, compressed air can cause many harmful effects and hazards in the tank and surrounding. Thanks for updating people about this.After reading this post, they will be able to understand the need of air receiver.
