CSZ-300 water-drive fan, axial type, explosion prevention
CSZ fans belong to the subgroup used in places with high danger, with anti-tilt signals, anti-vibration, impact resistance. The fan has a simple structure, light weight, simple operation as well as it has the ability to vent (usually requires only one operating person). Operated directly from fire protection water, this ventilation fan does not depend on any other source of energy with closed bearings. It reduces the majority of maintenance work. With wide applicability, this type of vent fan can work ideally for pipes containing vapors, explosive gases as well as other harmful substances and gases.
CSZ Fan Structure – 300
CSZ-type ventilation fans include water turbine systems, protective casings, rotors and propeller sets. Water turbines are precision molded with corrosion-resistant copper alloys and welding casings are made of austenitic stainless steel (1) (g-Fe), propellers are molded with high strength by aluminum alloys. Water turbines and rotors are sealed through 2 levels, contact and a copper safety washers are installed between the casing and the rotor, with a non-spark-emiting structure (explosion prevention). CSZ ventilation fans are designed for both air supply and air-sucking fans, but they cannot be used instead of each other.
(1) Austenitic austenitic, also known as gamma iron, gamma-phase iron (γ-Fe), is a non-metallic or solid solution of iron, with an alloying element.
