Production description
Backward Centrifugal blowers are used primarily for intake suction and do not require a scroll housing. They have high hydraulic efficiency.
Backward centrifugal impellers offer a quiet and compact air moving solution. The Permanent Split Capacitor (PSC) motors provide reduced operating costs and longer service life. Ball bearing construction allows multiple mounting options. Backward centrifugal impellers have low profiles that do not require an enclosure. Air is discharged 360° radially from the impeller wheel. These units operate very efficiently at high pressures.
