SPECIFICATION

Casing made of high quality ABS provides long lasting shock-proof and robust construction. The unit are finished in white RAL 9010 and are UV resistant.

Unique design winglet-type impeller, providing enhanced aerodynamic properties, low noise and increased efficiency.

Single-phase induction motors with integral thermal protection, mounted on high quality ball bearings. Suitable for continuous and intermittent running.

FEATURES & BENEFITS

IPX4 protection degree

Aesthetic front flat cover for modern interior design easily removed for cleaning.

Rigid optimised spigot support preventing distortion with strengthened guard and design to maximise airflow.

Integral back-draught shutter to prevent air flowing back into the room when the fan is off.

Low power consumption: 100mm model has less than 8 watts opearating power consumption for energy saving.

Totally recyclable plastic components, environmentally friendly. Double insulated: no earth connection is required.

Tested to the latest standards: units are tested in the TUV Rheinland recognised laboratory, meaning accurate, up to date information on electrical safety, performance and noise level that can be relied upon. Designed and manufactured in accordance with EN60335-2-80 (Low Voltage Directive) and the EMC Directive (Electromagnetic Compatibility).

VERSIONS

Standard

The fan is operated via a separate ON/OFF switch or the light switch.

Run-on timer

The fan is equipped with a adjustable timer circuit 1-25 minutes Operation: after switching off, the fan continues to run for the pre-set period of time.

Humidistat & timer

The fan is provided with an electronic circuit having a humidity sensor on board (adjustable from 50% to 95% RH) and a timer, adjustable from 1-25 minutes Operation: when the percentage of relative humidity is higher/lower than the pre-set threshold, the fan is automatically activated/ deactivated. After switching off, the fan continues to run for the pre-set period of time.
