Structure :

CBL Marine Explosion-proof Centrifugal Fan

There are two structural types:

type I (direct-coupling type), and type II (separate cabins type). The construction is non-sparking.

The structure of types I is a motor direct coupling one, the impeller is mounted directly on the motor shat , and the casing is fixed on the flange of the explosion-proof motor.

The type II is a separate structure ,the fan and the motor are put into different cabins, with a driving device, flexible couplings, and the driving device consists of bearings, bearing-box, shaft, brass rings, stuffing box. It can be oiled and measured the temperature .

The fan may be made into a horizontal or vertical , single-stage, single-drawing and airtight structure by the customer’5 requirements.
