Bathroom fan airRoxy pRim150 with timer — axial ventilation, model pRim150

The airRoxy pRim150 with timer is an axial bathroom ventilation unit designed for extraction of moist, stale air from bathrooms and small utility rooms. Compact and suited for through-wall or short-duct installation, this model combines straightforward installation with a built-in adjustable timer that allows delayed switch-off to maintain air exchange after the room light is turned off. The unit is intended to reduce humidity, limit condensation and odors, and support healthy indoor air circulation in residential settings.

Advantages

The pRim150 provides continuous axial airflow in a compact housing that fits typical 150 mm openings. Its integrated timer enables delayed shutdown for efficient moisture removal without additional controls. The design supports both wall and ceiling mounting and is compatible with short duct runs, making it suitable for retrofit and new installations where space is limited. Low installation complexity and a focus on practical functionality make it appropriate for domestic bathrooms and small service rooms.

How to use

Install the airRoxy pRim150 in a suitable opening in a bathroom or service room wall or ceiling according to local electrical and building regulations. Connect the unit to the existing light switch or to a separate control circuit to make use of the timer function: when the supply is interrupted, the timer keeps the fan running for the selected delay interval to remove remaining moisture. Ensure the discharge points and any short ducting are unobstructed and sealed to maintain effective airflow. Electrical wiring should be performed by a qualified electrician.

Usage recommendations

Set the timer to run for a period sufficient to remove residual humidity after showering or washing; typical delay settings range from a few minutes up to a quarter of an hour depending on room size and moisture load. Regularly inspect the intake and discharge openings and clean the fan grille to prevent dust build-up and preserve airflow performance.
