Rietschle Thomas’s RL Series rotary lobe blower measures six inches long and weighs only 1.75 lbs. The unusually small size is made possible through a patent-pending assembly process that minimizes leak paths within the blower chamber. The blower provides high flow at low pressure and is a good fit for applications including fuel cells, laboratory pressure and vacuum sources, particle counters and air samplers, gas boosting, and a variety of portable air-moving devices. Delivers air flow up to six CFM (56 LPM), pressure to two PSI (0.14 bar) and vacuum to 4 in. hg (-135 mbar).
