CSZ Series Marine Explosion-proof Fan With Water Driven for High Anti-hazard Classification in Marine Ventilation

1.Fan general

CSZ/CSL series explosion-proof axial fan with water driven have high anti-hazard classification, sound anti-wobble, anti-vibration and anti-impact performance. The fan of simple structure, low weight, simplicity of operation as well as its port-ability (normally only one operator of required)Driven directly by fire protection water, this ventilator depends on no other power with sealed bearings. It largely reduced the maintenance job. With a wide applicability, this type of ventilator can work at -35℃～250℃, ideal for ducting flammable and explosive gases or steam as well as poisonous or other harmful gases.

2.Fan structure

CSZ/CSL Series ventilator fan 15 composed of water turbine, frame ,casing, rotor and impeller The waterturbine15precisely Cast of anti-corrosion copper alloy and the casing 15 welding of austenitic stainless steel The impeller 15 cast of high strength sealing aluminum alloy. The water turbine and the rotor adopt two degrees of sealing, contact sealing and padding A safety brass ring 15 fitted between the casing and impeller, with the structure of no-spark design CSZ ventilator fan serve either supply or exhaust fan, but they can't displace use. CSL ventilator fan is composed of water turbine, frame, casing, rotor, impeller, etc. The water turbine is precisely cast o f anticorrosion copper alloy, the casing is soldered of austenitic stainless steel and the impeller is cast of high strength aluminum alloy, with the whole structure of no-spark design. The angles for air-outlet are R90° for air supply and R225° for air exhaust As a result, this type of ventilator can't change the model.
