Product Overview

Envirovent Silent 100mm extractor fan model with backdraught shutter - SIL100S

The Envirovent Silent 100mm Extractor Fan (SIL100S) delivers quiet, efficient ventilation for bathrooms, en-suites, kitchens, and utility areas at just 26dB loud. Designed with a sleek, modern finish, it seamlessly integrates into any space while helping to maintain fresher, healthier air. Operating at just 8 watts, this energy-efficient fan provides a strong airflow of 95 m³ per hour, keeping your rooms comfortably ventilated without driving up energy costs.

Equipped with a backdraught shutter, the SIL100S prevents unwanted air from entering the room when the fan is not in use. This feature helps reduce heat loss, maintain insulation, and stop cold drafts from coming through the ductwork, ensuring consistent indoor comfort even when the fan is off.

Easy to install and low-maintenance, this fan provides reliable performance for both domestic and light commercial applications. The Envirovent SIL100S combines energy efficiency, high airflow, and whisper-quiet operation, making it a practical and smart choice for maintaining optimal indoor air quality.
