Gents:
need some help selecting an air blower.
working on an air scour system for a large filter. air scour requirements are 150 cfm @ 5 psig. in effect, we are taking ambient air and blowing it thru a water filter during backwash to "stir it up". site is remote, and unattended. looking for a reasonably priced "air pump".
don't have much experience with blowers. and after a catalog search, it looks like there are several types (lobe, rotary screw, helical screw, reciprocating).
>at this operating condition, what types make sense?
>does one provide discharge check valve, block valve, and PRV like a water
pump? what other appurtanances are necessary?
thank you in advance for your help. Received on Sat Oct 18 09:46:00 2003
