FBY Series Mine Flameproof Press-in Axial Flow Local Ventilator Fan

FBY Series Mine Flameproof Press-in Axial Flow Local Fan is mainly used for underground local ventilation in coal mines containing explosive atmospheres such as gas or coal dust. It is also suitable for metal mines, chemical mines, tunnels and other factories and mines that use fans.

Power from 2.2kw – 30kw

Fan blow distance from 500m-1000m

Design advantages

1. The fan adopts a panel-type muffler structure. The entire outside of the flow channel of the fan is made of flexible materials, which greatly reduces the noise radiated outside the body by high-speed airflow. The noise when the fan is running is also relatively soft.
2. The outer diameters from the fan rectifier cap to the muffler core, to the motor base and the rear muffler cone must be consistent to ensure that the flow channel in the fan body is smooth, and also improves the pressure coefficient of the fan and increases the delivery rate. Wind distance.
3. The panel-type muffler structure uses a fixed end and a movable installation form for the muffler cotton, so that the muffler cotton can be replaced after failure, ensuring the muffling effect and extending the service life of the ventilator.

Product features

The structural form of this series of fans is mine explosion-proof type, and the shell and structural parts are welded with steel plates. Adopt the integral type of motor and shell, the whole structure is compact, durable and easy to maintain.
This series of fan adopts the direct connection of impeller and motor, with reliable transmission and safe use.
The frame of the motor is welded to the main air duct, and the motor is cooled by the airflow delivered by the impeller, which solves the heat dissipation problem of the motor and improves the service life of the motor.
Evenly distributed holes are drilled on the flange of the air duct to facilitate the connection of the tapered joint or the direct connection of the colloid air duct.When the conical joint is used to connect the fan with the colloid duct, the conical joint can be made into convergent or diffused type.
