FBD series (dⅠ) explosion-proof pressure-injection counter-rotating axial flow local ventilation fan, this product is manufactured according to MT755-1997 ‘Technical Conditions for Counter-Rotating Local Ventilation Fans’. It is currently the most ideal coal mine ventilation equipment both domestically and internationally.

The FBCDZ coal mine main ventilator is a commonly used axial flow main ventilation fan in underground coal mines, featuring a contra-rotating structure.

A Roots blower is a type of positive displacement blower, often abbreviated as Roots blower in English. The working principle involves two rotors with involute or similar shapes, a casing, side plates, and synchronous gears.

The kiln exhaust fan is a critical piece of equipment in the kiln system, primarily used to extract flue gases from the kiln, regulate internal pressure and temperature, etc.

An auxiliary combustion fan is a specialized ventilation device designed to actively supply air (or oxygen) to combustion systems such as boilers, industrial furnaces, incinerators, etc.

XQ-type inclined chute high-pressure centrifugal fan is specially designed for cement kiln systems, mainly used for material fluidization and transportation within the cement kiln system.

Desulfurization fans are used to overcome the flue gas resistance of desulfurization (FGD) equipment, to introduce raw flue gas into the desulfurization system, and to stabilize the pressure at the outlet of the boiler induced draft fan.

HVAC Systems: Used for ventilation and air exchange in large buildings, supply and return air in HVAC systems, providing fresh air indoors, and maintaining a comfortable indoor environment.

Wear-resistant centrifugal fans are centrifugal fans with excellent wear resistance, mainly used for conveying gases containing dust, particles, and other abrasive substances. They are widely applied in industries such as cement, steel, chemicals, and power.

Their core function is to extract high-temperature flue gas generated in industrial furnaces, boilers, incinerators, etc., while regulating system pressure, making them key equipment in high-temperature flue gas treatment systems.

The coal gas booster fan, also known as a high-pressure centrifugal blower, has been developed based on the trend of two-stage coal gas stoves, combined with single-stage coal gas generators.

The impeller of a centrifugal fan is its core component, responsible for generating air pressure and transmitting energy. The structure consists of the hub, blades, front disc, and rear disc. The hub fixes the impeller to the main shaft, rotating with it.
