Extra quiet
High airflow
Low power consumption
IP45 degree of protection
Integral back flow valve
Overheating protection
Durable
The casing and impeller are made of high-quality and durable UV-resistant plastic. High ingress protection rating ensures makes the fan the ideal solution for ventilation of a bathroom. The electronic components are protected with tight covers.
The intellectual impeller design makes the fan efficiency high and the service life long.
Low noise
The fan exhaust spigot incorporates specially designed air rectifiers to reduce air turbulence, increase air pressure and lower noise level.
Specially designed impeller aerodynamic profile provides high air flow and low noise.
Perfect for ventilation of premises with high requirements to noise level.
Different variants
TH variant has off-delay timer modification and humidity sensor.
TP variant has modification with off-delay timer with and motion sensor (reach distance up to 4 m, viewing angle up to 100°).
Maintenance free
The fan is designed for continuous operation and requires no maintenance.
Features
Motor and Impeller
Motor is placed on special anti-vibration dampers for vibration absorption and silent operation. The motor bearings are maintenance-free. In addition the motor is equipped with overheating protection.
Specially designed impeller aerodynamic profile provides high air flow and low noise.
Installation
The compact design enables wall and ceiling mounting. The shortened spigot for mounting into a ventilation shaft or connection to Ø100 mm air ducts. Wall mounting with screws.
Flexible air ducts may be used in case of remote location of the ventilation shaft. Connection of the air duct to the exhaust flange with a clamp.
Control
Fans can be manually operated via a separate ON/OFF switch or the light switch.
Version with Timer & Humidity sensor (TH). When humidity level is higher than the threshold, the fan is automatically activated. After switching off, the fan is running for the pre-set period of time.
Version with Timer & Motion sensor (TP). When motion is detected in the reach area, the fan is automatically activated. After switching off, the fan is running for the pre-set period of time.
