Description

USE Supply and extract ventilation systems installed in various premises.Mounting in kitchens, bathrooms and other humid premises.Compatible with Ø 100 up to 315 mm round air ducts.

DESIGN High-quality durable plastic casing.Aerodynamically shaped casing.Airtight mounting box.Centro 150 is compatible with 150 and 160 mm air ducts.

MOTORSingle-phase external rotor motor with a centrifugal impeller with backward curved blades.Equipped with ball bearings for longer service life.Integrated thermal protection with automatic restart.Dynamically balanced turbine.Some standard sizes have high-powered motors (Centro max).
For ventilation of premises with high requirements to noise level low-noise modifications are available (Centro L).
Centro V2 series: two-speed asynchronous motor with external rotor and centrifugal impeller with forward curved blades.

SPEED CONTROL Smooth speed control with a built-in electronic speed controller (option FR).
Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).Centro V2 series: Two-speed control with the external CDP-2/10 speed switch (available upon separate order).

MOUNTING
Due to compact design the fan is the ideal solution for mounting in limited spaces.Any mounting position.Wall or ceiling mounting with fixing brackets supplied as a standard or with a wire frame Halter Centro (available upon separate order).
Flexible air ducts are fixed on the fan spigots with clamps.

MODIFICATIONS AND OPTIONSFR – built-in smooth speed controller from 0 to 100 %. The fan is supplied with a pre-wired power cable with IEC plug as a standard. The cable modification with a standard electric plug is also available (FR1). max – high-powered motor.L - low-powered motor.
G – smooth speed controller with an electronic thermostat and an external temperature sensor that is fixed on 4 m power cable. The fan is supplied with a pre-wired power cable with IEC plug as a standard. The cable modification with a standard electric plug is also available (G1).GI – smooth speed controller with an electronic thermostat and a temperature sensor integrated into the air duct. The fan is supplied with a pre-wired power cable with IEC plug as a standard. The cable modification with a standard electric plug is also available (GI1).
V – built-in speed switch (for two-speed models).W – the fan is equipped with a pre-wired power cable and IEC plug as a standard. Modification with a standard electric plug is available (W1).
