Exhaust roof fans
Industrial fans
Axial-ROOF fan with light alloy die-cast impeller with wing-profile blades – Fibreglass roof – Base for securing toP the roof
EVT V = 7.000÷36.000 m3/h Pt = 6÷40 kg/m2
Use: suitable for the suctin of vitiated air flue gases and vapour from the environment.They are very useful during the summer season in those environments where air changes are necessary in order to keep the room ventilated. They are also used for the aeration of workshops, founderies, cement factories, tanneries, joineries, and for chemical mechanical and metallurgical industries where big air volumes have to be sucked at low pressure. Minimum working temperature – 20 °C, maximum + 60 °C.
CONSTRUCTION FEATURES:
Tower. The outside structures is of pressed steel sheet with double perforated flange for anchorage on the roof or at the end of a pipe, complete with bracket for placing the driving motor. Diecast helical rotor in lighy alloy (spark-proof) with ring countour blades dynamically balanced, assembled caantilevered on the driving shaft. The rotor’s blade angle is adjustable when the fan is stopped for the types from 710 to 1000.
Rain shielding roof which can be disassembled, made of fiberglass-reinforced plastic (polyester resin). The air direction is from the motor to the rotor, (it is always prossible to invert the airflow, i.e. from the rotor to the motor, by inverting the rotation of the motor, by disassembling the rotor and reassembling it overturned).
Special executions on request. Painting of the outside structure with acid and rust-proof paint. Spark-proof unit with explosion-proof motor.
Accessories on request. Anchorage base. Automatic opening shutters with the passing of the airflow.
exhaust towers high capacity centrifugal fan impeller- Fibreglass roof – Base for securing toP the roof
BT V= 1.300 ÷ 15.000 m3/h Pt = 13 ÷ 107 kg/m2
Use: the exhaust axial towers are suitable for the suctin of vitiated air flue gases and vapour from the environment.
They are very useful during the summer season in those environments where air changes are necessary in order to keep the room ventilated.
They are also used for the aeration of workshops, founderies, cement factories, tanneries, joineries, and for chemical mechanical and metallurgical industries where big air volumes have to be sucked at low pressure.
Minimum working temperature – 20 °C, maximum + 80 °C (+ 150°C with cooling fan).
CONSTRUCTION FEATURES
The group is formed by a hight capacity centrifugal fan wheel, which is statically and dynamically balanced. The centrifugal fan wheel is osperated by an electric motor of form B5-V1 and supported by a strong accident prevention galvanized net. It is installed on the building roof by placing it on its square basament and it is protected from the atmospheric agents by means of a fiber glass hood.
