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.
(1)Material: Impeller: galvanized sheet steel
Rotor: Coated in black plastic
(2)Bearings: Maintenance- free ball bearings
(3) Direction of rotation: Clockwise, seen on rotor (opposite cable exit), or viewing from inlet
(4)All models have reached UL approval, CE approval and CCC approval
(5)The type of protection is IP54. All models are fitted with an internal Thermal Overload Protection Device
(6)Mounting position: Shaft horizontal or rotor on bottom; rotor on top on request (Any)
(7)Insulation class is class B or class F
