Cvsair exproof axial duct fans bodies are manufactured from galvanized steel sheet. Use of steel increases durability, strength and use of galvanized sheets makes the fan corrosion-resistant and long – lasting. Aluminium alloy makes the impeller very solid. Fan case length is designed longer than the traditional exhaust fans and the fan body is flanged. Terminal box located outside of the fan case and there is a protection wire at suction side of the body to protect fan from solid particles. Protection class of the fan is H. With all those features fan parts ( engine, impellers, motors, body ) become very durable and steady. 

Exproof fan has received many certificates. For instance, certified according to the EN 14986:2006 / Design of fans working in potentially explosive atmospheres and certified according to the ATEX ( ATmospheres EXplosive ). Exproof products to be used or sell in European countries must have ATEX certification.
