Rooftec 250/2200S Roof fan

Rooftec 315/3900S roof fan from Harmann

Construction:

A rooftop radial fan with vertical discharge, the motor of which is mounted outside the stream of flowing air. The fan has been adapted to pump air with a maximum temperature of up to 1200C.

The enclosure is made of profiled AlMg3 aluminum sheet resistant to sea water and galvanized steel sheet (mounting plate, internal brackets). The octagonal shape of the fan housing has reduced the pressure loss of the air flow.

As standard, each fan has an air outlet protected by aluminum perforated sheet, a service switch and a drip tray for draining condensate and rainwater from the inside of the fan. The design allows the housing to be tilted in order to carry out servicing operations within the rotor (inspections, cleaning).

Temperature range:

-25 ÷ 80 °C - ambient temperature depending on the model,
120 °C - maximum temperature of the pumped medium.

Rotor:

A new generation dynamically balanced rotor in class G2.5, type B - with blades inclined backwards, made of powder-coated steel sheet. The rotors of the three-phase models are additionally equipped with a Taperlock collet, which provides better balancing quality and higher operational stability.
