Description
USE SPEED CONTROL

Supply and extract ventilation systems installed in premises with high requirements to the noise level.Compatible with Ø 100 up to 200 mm round air ducts.

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

DESIGN MODIFICATIONS AND OPTIONS

Aluzinc casing internally filled with thermal and sound-insulating layer of foamed polystyrene.The connection spigots are equipped with rubber seals.The fan is equipped with a power cord for standard size 100–250 or a terminal block for standard size 315.

FR1: smooth speed controller adjustable from 0 to 100 % and power cable with mains plug.G1: speed controller, temperature controller with external temperature sensor (cable length 4 m), power cable with mains plug.GI1: speed controller, temperature controller with integrated temperature sensor and power cable with mains plug.The G1 and GI1 modifications enable automatic speed control depending on indoor temperature. The optimal ventilation solution for premises requiring permanent temperature control as greenhouses, orangeries, etc.W1: power cable with mains plug.

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 impeller.

MOUNTING  

Fixed to wall or ceiling with a fixing bracket supplied as a standard.Flexible air ducts are fixed on the fan spigots with clamps.
