Single-stage centrifugal blowers are used for industrial air and gas handling with volumes up to 10, 000 SCFM, pressures from 0 to 60 in H2O, and 0 to 52 in H2O vacuum. The single-stage centrifugal scroll blower provides dependable air or gas movement at a wide range of selected pressures and volumes. FeaturesStable performance from minimum to rated flow without surge or pulsationsPower consumption proportional to the volume outputSystem volume adjustments can be easily made by throttling with an optional inlet or outlet damperSingle-stage centrifugal blowers are designed for a variety of plant and process applications that require uniform pressure air flow over an entire volume range.
