Calculation of ventilation

Plant ventilation

N – Number of fan(set)
V – Room Volume(m3)
n – number (time / hour)
Q – single Centrifugal fan rate(m3/hour)

Tunnel ventilation


N – Number of fan
T – Each fan thrust
Tt – Total thrust
△P – Total resistance
At – Cross-sectional area of tunnel

Outlet angle Drive-way

Usually from the motor side of the face , if the air outlet direction is face to the right. we call it “right type”, if face to the left ,call it “left type”.

A type: cantilever, bearingless
B type: cantilever, belt drive structure, belt wheel mounted in the middle of the two bearing seat.
C type: cantilever, belt drive, belt pulley on the two bearing seat outside.
D type: cantilever, coupling is arranged in two bearing lateral
E type: belt drive structure, two supporting bearings are installed on both sides of the casing
F type: the shaft of the shaft connecting the fan and the motor shaft connecting the transmission structure
