Cvsair roof type fans are produced according to the EN12101-3 / Smoke and Heat Control Systems standard. Motor insulation class refers to the maximum temperature that the motor can operate without stopping. With the H insulation class, fans can work at 180°C without stopping ( 130°C for B Class, 150°C for F Class ). Fans are made of galvanized sheet metal. With the help of zinc layers, fan parts become resistant to corrosion reactions. Electrostatic painting method, which is the most economic and qualified among painting techniques, is used in painting processes. With the specific changes of the wing structure, blades become aerofoil and high pressure zone is created at athe part of the upper wing surface. In this situation, static pressure increases. In addition, blade angles are adjustable for the maximum air flow efficiency. 

Three-phased motor are suitable to operate with frequency inverters. F300 or F400 heat resistance versions can be selected on demand and fans can be designed for exhausting polluted air or supplying fresh air.
