|USE||MODIFICATIONS AND OPTIONS|
Supply and extract ventilation systems installed in premises with high requirements to the noise level.Suitable for limited mounting space.Compatible with ∅ 100 up to 315 mm round air ducts.
max: high-powered motor.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.
Galvanized steel casing internally filled with 30 mm thermal- and soundinsulating layer made of non-flammable foamed polyurethane.The connection spigots are equipped with rubber seals.Fixing brackets for easy mounting.
Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).
Two-pole external rotor asynchronous motor with centrifugal impeller and backward curved blades.The motor is installed on specially designed vibration-damping mounts to absorb vibration and noise.Equipped with ball bearings for longer service life.Integrated thermal protection with automatic restart.Dynamically balanced impeller.
Fixed to wall or ceiling with a fixing bracket supplied as a standard.Flexible air ducts are fixed on the fan spigots with clamps.Power is supplied through an external terminal box.
