Sound-insulated inline fans
Use
Hot and highly polluted air extract up to
+120 °C in high resistance condition.
Kitchen placement extract systems (combi ned with grease filters).
Ventilation for baking halls.
Welding gas extract.
The fans is available for round air ducts
∅ 150, 160, 200, 250, 315, 355, 400, 450 mm.

Noise level: from 41 dBA
Design
Galvanized steel casing internally filled with 50 mm thermal- and sound-insulating layer made of non-flammable mineral wool.
The fan casing is installed on a supporting mounting frame with integrated vibration isolators.
The swivel motor-impeller block is attached to the swivel door which facilitates the fan servicing.
Motor
Single- or three-speed motor.
Galvanized steel impeller.
Equipped with ball bearings for longer service life.
Dynamically balanced impeller.
F class motor winding insulation and IP54 ingress protection rating.
Operation and speed control
Smooth or step-up speed control with an auto transformer or frequency inverter (both available upon separate order).
Mounting
Compatible with round air ducts. The spigot diameter matches the standard air duct sizes.
Mounting to the wall with the mounting angle bracket UM Iso-K . Available upon separate order.
External terminal box on the motor for connection to power mains.
