Tower-AM
Roof centrifugal fans
Use
Extract ventilation systems installed in various premises.
Roof mounting.
For any types of roofs or vertical ventilation shafts.
Compatible with ∅ 150 up to 315 mm round air ducts.
Air flow: up to 1920
533
m³/h
l/s
Power: from 98 W
Noise level: from 47 dBA
Design
Steel casing with a special polymer atmospheric resistant coating.
Horizontal air exhaust.
The fan is rated for continuous operation.
A connecting plate is designed to facilitate the fan mounting to the roof surface.
Motor
Single-phase external rotor motor and centrifugal impeller with backward curved blades.
Dynamically balanced impeller.
Equipped with ball bearings for longer service life.
Overheating protection with built-in thermal switches with automatic restart.
Speed control
Smooth or step speed control with an external thyristor controller or an external auto transformer (both available upon separate order).
Mounting
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 is perforated for fixing bolts that attach the fan to a stable level surface or a roof frame.
Roof frame, intake flange and fixing bolts are available on separate order.
Power is supplied through an external terminal box.
