The Aluminum Alloy Explosion-proof Axial Flow Fan is a new type of fan developed in China in the 1980s, based on the BT30-11 design. It is suitable for conveying flammable and explosive gases without corrosive properties, with an environmental temperature not exceeding 60°C. It is widely used for ventilation and air exchange in general factories, warehouses, offices, and residential buildings, as well as for strong heat dissipation. It can also be installed in series with longer exhaust pipe sections to increase pressure in the pipes. The motor can be removed to serve as a free-standing fan.

Overview

The Explosion-proof Axial Flow Fan is a new type of fan developed in China during the 1980s, based on the BT30-11 model and improved in design [1]. Compared to the BT30-11 fan, it boasts distinct advantages:

① More structurally sound;

② Performance significantly improved, full pressure efficiency reaches 89.5%;

③ Lower noise, noise reduced by 3.6 dB(A) compared to A-weighted level.

Explosion-proof axial fans are composed of explosion-proof motors, blades, and air ducts, etc.
