EnviroVent SIL125HT Silent 125mm Kitchen & Utility Extractor Fan with Humidistat & Timer

Ultra-Quiet 125mm Extractor Fan with Automatic Humidity Control & Adjustable Timer

The EnviroVent SIL125HT Silent 125mm Extractor Fan is a high-performance, ultra-quiet ventilation solution designed for kitchens, utility rooms and other areas where effective moisture extraction is required. Featuring an integrated adjustable humidistat and over-run timer, the fan can automatically respond to increased humidity levels and continue operating after activation to help remove excess moisture and condensation.

The SILENT 125 range uses a motor mounted on silent elastic blocks to minimise vibration and operating noise. Producing up to 50 litres per second of airflow while operating at just 33dB(A) at 3 metres, it combines strong extraction performance with exceptionally quiet operation.

The SIL125HT also incorporates a backdraught shutter, airflow guide vanes, sealed-for-life ball bearings and an IP45-rated construction, making it a dependable choice for professional domestic ventilation installations

Automatic Humidity Control

The built-in electronic humidistat can be adjusted between 60% and 90% relative humidity. When humidity rises above the selected level, the fan can operate automatically to help extract moisture-laden air, continuing until the required humidity level is reached.

This makes the SIL125HT particularly useful in rooms where condensation and changing humidity levels need to be managed effectively.

Adjustable Over-Run Timer

An integrated electronic timer allows the fan's run-on period to be adjusted between 1 and 30 minutes. This allows extraction to continue after switching, helping clear remaining moisture, odours and stale air from the room.

Ultra-Quiet Performance

EnviroVent's SILENT range is engineered to minimise vibration by mounting the motor on specially designed elastic blocks. The SILENT 125 operates at only 33dB(A) at 3 metres, while still providing a maximum extraction rate of 50 l/s.

Backdraught Protection

A backdraught shutter is included as standard, helping prevent unwanted air entering the property and limiting heat leakage through the ventilation opening while the fan is switched off.
