Body is made of sheet steel with electrostatic powder coating, or fiber reinforced with steel sheet. Rain Shield is made of Fiber Glass. Impeller is made of Glass-reinforced Polyamide, or cast aluminum alloy. The motors are IP55 class, 4 and 6-pole motors. Efficiency class IE3 and Class F insulated. Airflow direction is from impeller to motor. Variable pitch angle for achieving high aerodynamic efficiency and various discharge rates. The device is capable of exhaust air at maximum temperature 60 ºC.
The fan blades are manufactured in airfoil profile to provide regular flow. The Impeller of the fan is balanced dynamically based on ISO 14694. Air entry box is made of sheet steel with safety net for easy assembling with the roof.
It works with low noise levels and is designed to be maintenance-free for long periods of time. It provides a great advantage, especially in conditions where horizontal air is not absorbed. Since the rainwater is easily evacuated, water ingress is prevented from entering the indoor spaces.
It is used for ventilation of high-volume factory, warehouse and hangars. It provides the ideal solution for large areas with its moderate flow rates and static pressures.
Available 7 standard sizes from 500 mm to 1000 mm, Custom made sizes can be manufactured upon customer's request.
