- Designation key
Extract ventilation systems installed in various premises.Roof mounting.For any types of roofs or vertical ventilation shafts.
Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).
Steel casing with a special polymer atmospheric resistant coating.Vertical air exhaust.The fan is equipped with a terminal block for connection to power mains.The fan is rated for continuous operation.The upper cover is equipped with two eye bolts for easy fan lifting on the roof with hoisting mechanism.A connecting plate with an intake opening is designed to facilitate mounting to the roof surface.
Roof mounting directly above a ventilation shaft or air duct.The fan is connected to the air duct with the intake flange that is fixed to the fan base.The fan base has holes for fixing bolts that attach the fan to a stable level surface or a roof frame.Roof frame and intake flange available on separate order.Power is supplied through an external terminal box.
Two-, four- or six-pole asynchronous motor with external rotor and centrifugal impeller with backward curved blades.Single-phase (E) or three-phase (D) motor modifications.Dynamically balanced impeller.Equipped with ball bearings for longer service life.Overheating protection with built-in thermal switches with automatic restart or with leaded outside terminals for connection to external protecting controls.The thermal switch terminal leads are designed for connection to respective circuit of the overload relay or respective terminals of the autotransformer or thyristor speed controller.
