CSZ Series Marine Water-Driven Explosion-Proof Axial Fans

1. General
CSZ series marine water-driven explosion-proof axial fans have high-efficiency, energy-saving, explosion-proof, anti-corrosive, and anti-impact performance. The fan has a simple structure, low weight, simplicity of operation, and low maintenance. It is driven directly by fire protection water, so this ventilator depends on no other power. With sealed bearings, it can largely reduce the maintenance work and has a wide applicability. This type of ventilator can work at -35°C ~ +250°C, suitable for ducting flammable and explosive gases or steam as well as poisonous or other harmful gases.

2. Structure
CSZ series water-driven explosion-proof fans are composed of water turbine, frame, casing, rotor, and impeller. The water turbine (excluding cast of anti-corrosion copper alloy) and the casing 15 are of austenitic stainless steel. The impeller 15 is of high strength corrosion-resistant aluminum alloy. The water turbine and the rotor adopt two degrees of sealing, contact sealing and padding. A safety brake ring 15 is fitted between the casing and impeller, with the result that this no-spark design CSZ ventila – tor fan serve either supply or exhaust fan, but they can’t displace use.
CSZ ventilator fan is composed of waterturbine,frame, casing, rotor, impeller,etc. The water turbine is precisely cast of anti-corrosion copper alloy,the casing is welded of austenitic stainless steel and the impeller is cast of high strength corrosion-resistant aluminum alloy. The whole fan is of non-spark design. The angles for air outlet are 800 for air supply and 8250 for air exhaust. As a result, this type of ventilator can’t change the model.
