Free Air Flow

Gast advertises blower performance in Free Air Flow, or air subjected to only atmospheric pressure. (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 and
a specific discharge pressure at the exhaust port, which can be perceived as enhanced performance over Free Air Flow rated blowers. Therefore, we are also
providing the following vacuum performance for Gast blowers in CFm Inlet Air for comparison to other blower manufacturer’s advertising.
