Bathroom Exhaust Fan AWENTA WPAB110ZT Pulsar 100 mm, 110 m³/h, 9 W, 230 V, timer and backdraft damper, white

The AWENTA WPAB110ZT Pulsar is an axial bathroom exhaust fan designed for efficient removal of humid air from bathrooms and toilets. With a 100 mm duct connection and nominal airflow of 110 m³/h while consuming 9 W at 230 V, this surface-mounted unit provides continuous or intermittent ventilation for residential and small commercial washrooms. The device includes an adjustable timer switch to maintain extraction after the room is vacated and an integrated backdraft damper to prevent reverse airflow. The white finish suits standard interior décors and the compact form factor allows straightforward installation on wall or ceiling surfaces.

Advantages

The fan combines low power consumption and effective airflow performance to balance energy use and ventilation needs. The adjustable timer allows control over post-occupancy extraction time, reducing residual humidity. The built-in backdraft damper prevents outside air or odors from entering when the fan is off, eliminating the need for separate non-return valves. Surface-mounted design and standard 100 mm duct connection simplify replacement and retrofitting in existing installations.

How to use

Install the fan on a suitable wall or ceiling surface with a compatible 100 mm duct run to the outside or to the building’s ventilation system. Connect the unit to a 230 V supply following local electrical codes and using the timer setting to determine the required post-occupancy run-on period. Operate the fan via the building’s light switch or a dedicated switch as configured at installation; when switched on the unit extracts humid air, and after the light or switch is turned off the adjustable timer continues operation for the set interval. Ensure the backdraft damper is oriented correctly toward the external opening to prevent reverse airflow when the fan is not running.

Usage recommendations

For reliable performance, position the fan to achieve direct air path from the wettest area (typically above the shower or near the bath) to the external duct outlet, avoid long or excessively flexible duct runs, and schedule periodic cleaning of the inlet grille and impeller to maintain airflow. If the installation requires quiet operation or higher airflow, consider evaluating duct layout and insulation or consult a ventilation professional for system-level adjustments.
