The SDF tunnel construction axial flow fan is mainly used to discharge harmful gases released during tunnel excavation, such as those from explosions and internal combustion engines, providing a good working environment for tunnel construction, maintaining the health of workers, ensuring normal and smooth construction, improving work efficiency, and guaranteeing project quality.

Jet fans are a special type of axial flow fan primarily used for ventilation and air exchange in tunnels, underground parking lots, and similar environments.

Smoke exhaust fans are ventilation devices used to expel smoke, hot air, and toxic gases, widely applied in building fire protection, industrial exhaust, and other fields.

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.
