Bathroom extractor fan AWENTA WPAB110ZH Pulsar 100 mm, 110 m³/h, 9 W, 230 V, timer, humidity sensor, check valve, white

AWENTA WPAB110ZH Pulsar is a compact bathroom extractor fan with a 100 mm duct connection designed for continuous or humidity-controlled ventilation of bathrooms, toilets and small wet rooms. The unit delivers a rated airflow of 110 m³/h while consuming 9 W at 230 V, combining efficient air extraction with low power use. Integrated controls include an adjustable timer and a humidity sensor for automatic start/stop operation, and a built-in check valve prevents backflow when the fan is off. The fan is finished in white and intended for wall or ceiling mounting to maintain indoor air quality and reduce condensation and odors.

Advantages

The AWENTA Pulsar fan provides reliable moisture removal and odor extraction with a high airflow-to-power ratio, achieving 110 m³/h at only 9 W. The built-in humidity sensor enables automatic operation based on relative humidity, reducing manual intervention and helping to prevent mold growth. An adjustable timer allows continued extraction after the room is vacated, and the integrated check valve prevents outside air or duct odors from entering when the fan is idle. Its compact 100 mm duct connection simplifies installation in standard residential ventilation systems, and the neutral white finish fits typical bathroom interiors.

How to use

Mount the extractor fan in a 100 mm duct or compatible ventilation opening on a wall or ceiling following local electrical and building regulations. Connect the unit to a 230 V supply and set the timer and humidity threshold according to the desired behaviour: enable humidity-controlled mode for automatic operation when relative humidity rises, or use continuous mode where appropriate. After occupancy, the adjustable timer keeps the fan running for the selected interval to clear residual moisture before switching off. Regularly inspect and clean the grille and impeller according to the manufacturer’s maintenance guidance to preserve airflow performance.

Usage recommendations

For optimal performance, position the fan close to the moisture source (for example above a shower or near a bath) and ensure the ductwork is as short and straight as possible to minimise airflow resistance. Use the humidity sensor setting to prevent prolonged high humidity levels, and check the check valve periodically to confirm it moves freely. For installations in larger spaces, consider additional ventilation points or a higher-capacity unit.
