Envirovent SIL100 Range

The Envirovent SIL100 range offers a variety of extractor fans designed to suit different requirements. Each model shares a common set of features such as high air extraction rates, low noise levels, and a generous 5-year warranty. Let's explore the different functions available in the SIL100 range:

  1. Standard: The standard model provides a reliable and efficient extraction solution, ensuring that excess moisture and odors are effectively removed from your bathroom.

  2. Timer: The timer model includes an adjustable overrun timer that allows you to control the fan's operation after the bathroom is vacated, ensuring that it continues to extract air for a specific duration to eliminate residual humidity.

  3. Intelligent Timer: This is the newest addition to the SIL100 family, the intelligent timer. This function means the fan will calculate the amount of time the fan will need to overrun, depending on how long the fan has already been running for.

  4. Humidistat: The humidistat model utilizes a built-in sensor to monitor humidity levels. When the humidity exceeds a predetermined threshold, the fan is triggered, effectively eliminating excess moisture from the bathroom.

  5. PIR (Passive Infrared): The PIR model features a passive infrared sensor that detects movement within the room. This ensures that the fan is activated when someone enters the bathroom, guaranteeing effective extraction during periods of occupancy.
