Cvsair smoke exhaust fans are manufactured with galvanized ( zinc ) coating.  Zinc layers are oxidized more quickly than the metal layers therefore the fan metal is not damaged. This fact prevents the formation of rust and corrosion. With help of aerofoil-section blade friction forces are optimized. Blade angle is adjustable for the maximum airflow efficiency. Three-phased motors are suitable to operate with frequency invertors. Airflow starts from the motor side and finishes at the impeller side. All parts are produced according to the EN 12101-3 certificate. Highly efficient IE2 motors with Class-H insulation and IP55 protection can be designed to operate dual sided on demand.

Axial smoke exhaust fans are designed for working outside with either vertical or horizontal placement.  Vibration dampeners are mounted during installation process and the dampeners are also produced with connection flanges which enables to use silencer with or without pods. 60 Hz option is available.
