Water Turbine Fan

 

 

Water Turbine Explosion Proof Fans, Model WTF-300, WTF-400

 

 

1.     General
 

Teryair© Water Driven Turbine Explosion Proof Fans are designed

for high-performance ventilation of gas from large enclosed areas or other tank openings. Work effectively providing penetration deep into the tank for complete ventilation. These fans are made of non-spark construction with a stainless-steel impeller and integral water motor. These components are manufactured from corrosion proof material. Driven directly by water, this ventilator depends on other power with sealed stainless-steel bearings; it largely reduced the maintenance job. With a wide applicability, this type of ventilator can work at ambient temperature

 

﹣20℃ to +40℃, ideal for ducting flammable and explosive gases or steam as well as poisonous or other harmful gases.

 

2.   Structure
 

Teryair© Water Driven Turbine Explosion Proof Fans are composed of water turbine, frame, casting, rotor, impeller, etc. The water turbine is precisely cast of anti-corrosion copper alloy, the impeller is cast of stainless steel, the fan blades are aluminum, casing is cast of high strength aluminum alloy with SS bearing makes the whole structure of no-spark design.

The fan blades are aluminum so non-sparking even in event of collision with body which is bronze and aluminum construction.

The turbine is completely water filled during operation; no sparking possible
