(See above curves)Some blower manufacturers advertise vacuum performance in CFM Inlet Air - measurement of the suction of air at a specific temperature at the inlet port anda specific discharge pressure at the exhaust port, which can be perceived as enhanced performance over Free Air Flow rated blowers. Therefore, we are alsoproviding the following vacuum performance for Gast blowers in CFM Inlet Air for comparison to other blower manufacturer’s advertising.mbar inHg300 9.08.02507.0200 6.05.01504.0100 3.02.0501.0inH 2 0125100755025R7R6R6PR6PPR9R7PVACUUMR9P0 0 200 400 600800 100012001400 CFM400 800 1200160020002400CFM Inlet Air3m /hwww.gastmfg.comGast Regenair® Regenerative Blowers 9
