Description
USE

Supply and exhaust ventilation systems installed in various premises.Suitable for use as ventilation or air conditioning system components.Compatible with round and rectangular air ducts.

DESIGN

Compact scroll casing is made of steel and is covered with a special polymer coating.The fan is equipped with a round intake flange and exhaust rectangular flange for connection to respective air ducts.External terminal block for power supply.The fans are equipped with fixing brackets to facilitate fastening at any level surface.

MOTOR

Two- or four-pole asynchronous motor with external rotor and centrifugal impeller with forward curved blades.Equipped with ball bearings for longer service life.Integrated thermal protection with automatic restart.Dynamically balanced turbine.

SPEED CONTROL 

Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).

MOUNTING

The fan is designed for installation as a single unit or as a component unit of ventilation chambers or air conditioning units.The fan has a connection possibility for two air ducts, a rectangular discharge air duct through the flange on the casing as well as a round intake air duct through the connecting flange FRZ-H. Available upon separate order.In case of rectangular discharge air duct connection a discharge vent must be covered with the SG-H grille to protect the fan from foreign object ingress. Available upon separate order.

The vibration isolators, either of rubber type SI-G are recommended for noise and vibration attenuation. Vibration isolators reduce dynamic loads on the fan, enhance reliability and durability of the ventilation equipment. The vibration isolators are attached through holes in the mounting pad. Available upon separate order.


SI-G

Power is supplied to the fan through an external terminal box with sealed electric lead-in.
