Hot dip galvanized coating is used on the body of the machine. With the help of galvanized sheets corrosion reactions will be prevented and lifetime of fans will be very long. Blade of the fans are made of aliminium and wings are designed as aerofoil. Air flow can be controlled with maximum efficiency thanks to the adjustable blade angle. Fan motors are produced as a three-phased therefore they can be operated with frequency inverters. Motors can also be manufactured with double speed option on demand.
Roof Type Axial fans are certified with H-Class insulation in according to EN12101-3 / Smoke and Heat Control Systems Standard and F300, F400 temperature resistance classes in smoke extraction. The FCL version fans can be used in up to + 60 °C ambiance tempeture of the exhaust air or on the fresh air supply.
There are eleven different versions of roof type axial fans from CVS – RH – Ø400 to CVS – RH – Ø1250. For the version of CVS – RH – Ø400; voltage is 400, power is 0,55 kW, current is 1,27 ( A ), frequency is 50 Hz, speed is 2780 rpm ( revolutions per minute ) , Y Type wiring diagram and Sound PL ( db ) 3m is measured as 63. The external diameter of fan is 560 millimeter and the internal diameter is 400 millimeter. Height of the D-150 version is 220 millimeter. Air flow at 300 Pa pressure is measured as 4000 cubic meters per hour.
