Explosion-Proof Axial Flow Fan, Explosive Gas Axial Flow Exhaust Fan

It is suitable for ventilation in workshops, warehouses, laboratories, etc. Its explosion-proof series is ideal for ventilation in inflammable and explosive gas environments.

There are 46 types of this ventilator, among which there are 9 machine numbers of 3 blades, 6 blades, 8 blades, and 9 blades. According to the diameter of the impeller, the order that is arranged from small to large is №3, №3.5,  №4, №5, №6, №7, №8, №9 and №10; There are 10 machine numbers of 4 blades. According to the diameter of the impeller, the order that is arranged from small to large is №2.5, №3, №3.5, №4, №5, №6, №7, №8, №9 and №10.

This ventilator consists of three parts: an impeller, a case, and a wind collector:
The impeller consists of blades and the wheel hub and so on. The blade is welded to the outer circumference of the wheel hub with a thin steel plate according to the required mounting angle. The impeller case ratio (shaft, disk diameter to impeller diameter) is d(-)=0.3.

All of the blades are stamped into similar shapes. For the mounting angle, 3 blades are divided into five types 10 degrees, 15 degrees, 20 degrees, and 35 degrees; 4 blades, 6 blades, and 8

Blades are divided into five types 15 degrees, 20 degrees, 25 degrees, 30 degrees, and 35 degrees. The impeller is directly mounted on the motor shaft, of which №3 to №8 adopt two kinds of motor rotation speeds, while №9 and №10 adopt a kind of motor rotation speed. The air volume ranges from 550 to 49,500 m3/h and the wind pressure ranges from 25 to 505 Pa.
The case part is composed of a wind cylinder and a bottom frame, etc., while the bottom frame is divided into two types that are made of thin steel plate or proximate matter.
Air collector part: The air collector is a circular streamline, which is stamped from a thin steel plate, to reduce airflow inlet loss.
