Bathroom Extractor Fan airRoxy pRim150 with Humidity Sensor, model 01-012

The airRoxy pRim150 with Humidity Sensor (model 01-012) is a compact ceiling or wall-mounted bathroom extractor fan designed to control moisture and odors in small humid spaces. The unit integrates an automatic humidity sensor that switches the fan on and off according to relative humidity levels, enabling both continuous and intermittent operation. Its form factor fits common duct sizes and installation points in residential bathrooms, toilets, and utility rooms, providing reliable air exchange to reduce condensation and protect surfaces from damp-related damage.

Advantages

This extractor fan combines automatic humidity control with straightforward installation for flexible use on ceilings or walls. The built-in sensor removes the need for separate control units, allowing the fan to start and stop based on measured humidity. Designed for quiet operation and efficient airflow, it helps prevent mold growth, reduces lingering odors, and supports a healthier indoor environment. The compact design and neutral finish suit most bathroom interiors without requiring major modifications.

Suitable for

• Residential bathrooms and en-suites
• WC rooms and guest toilets
• Small utility rooms and laundry areas
• Areas requiring automatic humidity-controlled ventilation

Key specifications

• Mounting: ceiling or wall installation
• Operation: automatic humidity sensor with on/off control; supports continuous and intermittent modes
• Application: designed for small bathrooms and humid rooms
• Airflow performance: suitable for typical domestic bathroom ventilation rates
• Noise level: engineered for low-noise operation suitable for residential spaces
• Design: compact housing compatible with standard duct connections

How to use

Install the extractor fan on a suitable ceiling or wall location with access to the duct or external vent according to local installation rules. Connect the electrical supply and set the humidity threshold if adjustable; otherwise the factory setting will trigger the fan at elevated relative humidity. The unit operates automatically when the humidity sensor detects moisture above the set point and turns off when levels return to normal. For continuous ventilation, configure wiring or switch settings as required to maintain low background airflow.

Usage recommendations

Position the fan to provide direct extraction from the wettest area of the room, typically above the shower or near the bath. Ensure the duct path to the outside is as straight and short as possible to preserve airflow efficiency. Regularly check and clean the grille and impeller to prevent dust buildup and maintain sensor accuracy. Follow local electrical and building codes during installation and consult a qualified installer if unsure about wiring or ventilation sizing.
