Secondary Receiver Tank, Anyone???

You’ve guessed it. I’m going to talk about compressed air receiver tanks today. But, not the big ones you see sitting next to the compressor or the aftercooler out back where the compressed air is produced. No, I would like to have a short discussion on the smaller ones that can be used throughout the compressor system. These (usually smaller) air receiver tanks can be placed close to applications where there are requirements for relatively short, high air consumption rate “events”. An “event” is any situation where compressed air is used.

Your next question might be, “Why is he bringing this up?” The answer is quite simple. In applications where you have a large rate of air demand over short periods of time, a receiver tank mounted close by to absorb the draw to the system makes perfect sense. In this case, a receiver tank does two things:

1. It allows the item using the compressed air to operate at full functioning pressure and volume to perform the intended task as designed.

2. It prevents that demand for compressed air from affecting the rest of the system, including the air compressors by acting as a bit of a shock absorber.

Air compressors “react” to demand by sensing pressure in the system and producing compressed air volume to compensate when there is a drop in pressure. The receiver tank takes that one compressed air event that may happen for perhaps only a few seconds and spreads it out over 1 or more minutes to even out the demand that the rest of the compressed air system sees over time.

So, instead of using the primary storage and compressed air piping system to blast out a huge volume of air for only one application, you can prevent the shock to the system and turn it into a continuous, smaller demand.  So, as they say, slow and steady wins the race in keeping your air compressor system operating as efficiently as it can. In some cases the use of a secondary receiver can make the difference as to whether a new compressor has to be purchased or not.

Do I have your attention now?

Oh, did I mention that EXAIR does have a 60 gallon receiver tank available for use with our products? We most certainly do. It is a 60 gallon model that we are making available for the express pupose of secondary air storage close to the application where you need it.

You can also use the EFC (Electronic Flow Control) in conjunction with the receiver tank to power any one of the many products EXAIR provides for various air moving applications.

If you think you might have an application that could benefit, please give us a call, send an e-mail or hop onto our chat to discuss the details.  Thanks!

  1. Hi Sir,
    Regarding this, Just wan to know if the pressure rating for the secondary air receiver is just the same with the Primary air receiver?

    1. Hello – generally speaking the pressure in the secondary receiver could be the same, or slightly less, than the primary receiver. Also, the pressure in the secondary receiver is typically higher than the pressure needed at the end us of the compressed air. The air moving out of the secondary receiver is regulated down to meet the lower pressure need of the end use.
