Inovation

The centrifugal impeller of unique design exerts high pressure, enabling air to traverse air ducts 8 times longer than the classic axial impeller, and ensures resistance to pressure fluctuations in ventilation systems.

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.

Easy to clean

Easy to use removable front panel and dishwasher washable filter element protects the fan internal components against dust penetration.

Low noise

The centrifugal fan impeller has forward-curved blades for high pressure and low noise levels.

Features

Motor and Impeller

The motor bearings are maintenance-free. In addition the motor is equipped with overheating protection.
The impeller's shape ensures low noise and exerts high pressure in long air ducts.

Installation

Designed for wall and ceiling surface mounting. Fixed to wall by self-tapping screws.

Flexible duct application is recommended in case of remote location of the ventilation shaft. Fastening with clamps in case of flexible duct connection.

Control

Fans can be manually operated via a separate ON/OFF switch or the light switch.

Version with Timer (T). The fan is equipped with a turn-on delay timer, turn-off delay timer and an interval timer (30 minutes every 4 hours).

Version with Timer & Humidity sensor (TH). The humidity sensor has two modes. In the Manual mode when humidity level is higher than the threshold, the fan is automatically activated. Auto mode - continuous intelligent humidity control. Optimal humidity based on analyzing the indoor air humidity level statistics. The fan is equipped with a turn-on delay timer, turn-off delay timer an interval timer (30 minutes every 4 hours).
