This series fans have been examined and proved up to standard by Explosion-proof Inspection Authority of the PRC and have got the centrificate of inspection. They have als been examined by the Register of shiping of China and have got the centrificate.
Application
The explo, sion-proof symbol of explosion-proof fans is EdIIBT4 They can be delivered for gas mixtures or vapour containing combustibles and explosives, for ordinary air, fo, r sea air containing salf fog, for air containing oil fog and other corrupt air supply or extracition.
These explosion-proof fan series are best suited to pumping out gas mixtures or vapour containing combustibles and explosives in oil cabins holds, pump-rooms, battery cabins, ammunition cabins, hangars, paint houses, etc. They can also be used for ventilation of other compartments of shipping and corresponding place of land's.
AC 50Hz, 380V or 60Hz, 440V type YB-H(explosioninsular) for marine use may be mounted on these fans.
Operation Conditions
For places where there are explosive gas mixtures of grade II B and group T4.
Ambient temperatures: -25degree~+50degree
Relative humidity of the air: ≤ 95%
Cyclical vacillation: 22.5° ~45° (Vacillation cycle 5~10S)
Sustained horizontal tilting: 15°
Sustained vertical tilting: 10°

Structural Types
CBL type:
There are two structural types: Type I (motor-direct-driving type) and type II (Separate cabins type). The construction is spark free.
The structure of type I is a motor-direct driving one, The vane wheel is mounted directly to the motorshaft. And the housing is fixed on the flange of the explosion-proof motor.
The type II is a separate structure, i. E. The fan and the motor are put into different cabins, with a driving device, a pairs of flexible coupling. And the driving device consists of bearings, bearingbox, shaft, brass rings, stuffing. It can be oiled and measured temperature. One side is fixed on the fan, and the other side will be mounted on the bulkhead.
The fan may be made into a horizontal or vertical, singlestage, single-drawing and airtight structure by the customer's requesting.
The fan can be made into a conter-clockwise rotating type or a clockwise one.
The counter-clockwise rotating type(Left turning type)-Taking a front view from the motor side, you will see the vane wheel turns counterclockwise. We use"L" to indicate it, and by the same way, the clock wise rotating type can be indicated as "R".
The outlet position of the fan, according to the rotating direction of the vane wheel, is made into the following main types. By your requesting, the outlet position is allowed to use other types, the nagle of which 30° Or 22.5° .
Features
CBL type:
Explosion-proof, safe and reliable in operation
Small in size, light in weight, and low in noise
Well anticorrosive
Strongly capable of resisting vacillation, vibration and shocking
Type Explanation
The type of explosion-proof fans are expressed by the first letter of the Chinese phonetic name, the outer diameter of the vane wheel, the standard speed, and the power of the explosion-proof motor, etc.
For example:
(CBL-15/0.75-2920)R90° ;
