The fans are equipped with three-phase (400 V, 50 or 60 Hz) single-speed or two-speed electric motors with IE3 energy efficiency class on request.
Motor ingress protection rating is IP55.
Power of applied electric motors:
• 4-pole – up to 132 kW, for fan size 1600 – 50 Hz.
• 6-pole – up to 90 kW, for fan size 1600 – 60 Hz.
Impeller
Aerodynamic impeller blades ensure high efficiency of the fan while keeping noise well under control.
The impellers are dynamically balanced.
Low weight and low moment of the impeller inertia help reduce the fan start-up time.
The fan blades can be made of the following materials:
• PAG – fiberglass reinforced polyamide for pressurization fans
• AL – die-cast aluminium for pressurization and smoke extraction fans
• ST – steel for smoke extraction fans
For smoke extraction fans, only impellers made of die-cast aluminium or steel are used, capable of operating according to the selected fire resistance class of the unit.
Please confirm the blade material while placing your order.
Mounting
The fans can be mounted on any flat surface or directly into a ventilation duct.
The units are suitable for both horizontal and vertical configurations.
In-duct installation requires flanges to attach the fan to the ductwork.
To attach the fan to the floor, a wall or the ceiling use the O-AF carriers (not included as standard, should be purchased separately).
The units are suitable for installation on rooftops to provide direct supply of outdoor air to the stairway areas.
