Blower

1,Explanations on GM model (e.g. GM35)

G--Initial of the GEAR-INCREASED 
M--Initial of the MIXED-FLOW TYPE 
35--Equivalent diameter of the impeller (in cm) 
GM 35L-------“L”for low pressure, and“H”for high pressure

GM series air blower is of the structure of a single-stage overhung type, axial intake and radial exhaust. Air passes through the inlet duct with silencer and enters suction pipe and inlet guide vane. This is connected by the main driver through coupling to speed-increasing gear, which increase the air pressure by driving the 3D mixed-flow semi-closed impeller rotating at high speed. The air is exhausted through the diffuser, spiral housing and diffusing pipe. The lube oil is supplied by the main oil pump which is connected directly to the driving shaft, and by the electric auxiliary oil pump when starting and shutting down. The axial thrust of the high speed rotor is transferred from the thrust collar to the low speed shaft, greatly reducing the mechanical losses.
