Hot-dip galvanized coating is used in the body of the Cvsair horizontal throw axial roof fan. With the help of galvanized sheets, corrosion (zinc layer reacts faster than the fan metal and prevents damage to the fan metal) reactions are prevented and the service life of the fans is greatly increased. The fan blades are made of aluminum and the blades are designed as aerofoil. Airflow can be controlled with maximum efficiency thanks to adjustable blade angles. Fan motors are produced as three-phase, therefore they are suitable for working with frequency inverters. Engines can be produced optionally with double speed option.

Roof Type Axial Fans are certified with Class H insulation according to EN12101-3 / Standard for Smoke and Heat Control Systems and F300, F400 (the ability to operate for 120 minutes at 300°C and 400°C temperature levels) in smoke evacuation. FCL model fans can be used for exhaust air discharge and fresh air supply at ambient temperatures up to + 60°C.
