Product Description

Smoke Exhaust Fans is a ventilation device specially designed to remove smoke and harmful gases produced during fires. They are usually installed in the smoke exhaust systems of buildings, especially in high-rise buildings, underground garages, tunnels, large shopping malls and other places that require emergency evacuation. Here are some basic information and technical details about Smoke Exhaust Fans:

The fundamentals of Smoke Exhaust Fans

Smoke exhaust fans generate airflow through rotating blades to discharge smoke and harmful gases from the fire source to the outside of the building, to reduce the obstruction of smoke to personnel evacuation and fire fighting work, and to protect the areas not affected by fire from smoke.

Main type

Axial flow smoke exhaust fan: the air flow along the blade axial flow, suitable for low resistance, large flow occasions.

Centrifugal smoke exhaust fan: the airflow enters from the axial direction, and then turns to the radial outflow under the action of the blade. It is suitable for the occasions of high resistance and small and medium-sized flow.

Smoke Exhaust Fans Application scenarios

High-rise building: Used for stairwells, elevator shafts, corridors, etc.

Underground garage: Quick clearance of smoke from fire.

Subway stations and tunnels: Ensure safe evacuation of passengers and staff.

Industrial facilities: such as chemical plants, warehouses and other places that need emergency smoke exhaust.

Product parameter

Model, specification, technical parameters:

The blade type adopts axial flow: there are two kinds of fire exhaust fans, GYF-I (single speed) and GYF-S1 (double speed).

Blade type adopts oblique flow: GYF-11 (single speed) and GYF-S2 (double speed) two kinds of fire exhaust fans.

If the user has a high demand for noise, it can be made into GYF-BX silencer fire exhaust fan. The fan can also be made of vertical, installed on the roof for fire smoke exhaust.

GYF-I fan has 15 machine numbers and specifications including NO4 ~16, air volume 3927 ~116768 m3/h, full pressure 372-972Pa.

The GYF-S1 fan has 10 machine numbers and specifications including NO5~14, and the air volume is 1470~87985 m
