    High-Performance Ventilation Designed for Modern Spaces

    • Compact & Versatile Design: Features a short tube design, ideal for spaces with limited wall or ceiling clearance. Whether you need a wall-mounted unit or a bathroom exhaust fan ceiling installation, its modern design with colorful front panels is easy to wipe clean.
    • Unmatched Suction Power: Built with a 100% copper, ball bearing motor that is highly energy saving. It delivers a strong suction power with a high wind pressure of 49Pa (compared to the usual 25Pa). Even when connected to long-distance ducts, it can smoothly exhaust air and quickly expel moisture to prevent indoor mold.
    • Whisper-Quiet Operation: As a low noise bathroom exhaust fan, it operates quietly so it won’t interrupt a relaxing bath or your favourite playlist.
    • Built for Wet Environments: Fully water proof with an IP44 rating, making it suitable for kitchens, bathrooms, and toilets.

    Advanced Features for Ultimate Moisture Control

    Smart Humidistat Feature
    Smart Humidistat: Upgrading to an extractor fan with humidity sensor means automatic protection. When the humidistat detects high humidity in the room, this will trigger the fan to start automatically, regardless of whether the fan is switched on at the wall. This is highly useful where the bathroom might remain humid for a period of time after use.
    Adjustable Overrun Timer Feature
    Adjustable Overrun Timer: A fan with a timer can be set to run after it has been switched off. The adjustable time is from 2 minutes to 30 minutes, meaning that humid air from a bathroom will continue to be extracted after someone has left the room. This design serves both convenience for the user and protection for the bathroom against moisture damage.
    Interval Operation Function Feature
    Interval Operation Function: For continuous air quality control, the extractor fan runs for 1 hour every 4/8/12/24 hours (adjustment), ensuring efficient ventilation.
