Zone One Fans

Zone One is the exterior of a bath or shower tray up to 2.25 meters above the floor. Equipment here will have a high chance of water exposure due to their closer proximity to the water sources.

While Zone Two fans require a minimum IPX4 rating, Zone One fans need an IPX5 rating, highlighting a better resistance to splashes due to the higher level of water exposure.

Installing a Zone One fan has multiple benefits, including:

1. Better moisture control
2. Improved air quality
3. Reduced condensation within the home

The closer proximity to the source of humidity allows Zone One fans to extract moisture vapours faster than Zone Two fans, which helps to reduce dampness in a house. This not only prevents mold and mildew buildup but also helps protect walls, ceilings, and fixtures from long-term moisture damage.

With an extraction rate of 27 litres per second (97m³/hour) and a specific fan power of 0.27 W/l/s, this fan operates quietly at just 25dB from 3 meters away. It features a user-settable overrun time delay (2–30 minutes) and a humidistat adjustable between 60-90% RH, making it ideal for through-wall applications or ducting under 2m. Its compact design ensures easy installation, making it a practical choice for modern bathroom ventilation. Supplied with a one-shot thermal fuse, it complies with BS EN 60335-2-80 for safety and reliability.
