Envira-45 100mm Zone 1 Fan

The ENVIRA-45 is a next-generation ventilation fan, engineered to tackle mould and condensation in your home, without losing valuable heat.

What sets the ENVIRA-45 damp control unit apart is its advanced alternate flow heat recovery system.

First, it extracts stale, humid air from your room, capturing the heat before it escapes. Then, it reverses direction, drawing in fresh outdoor air and warming it with the stored heat.

This efficient two-minute cycle runs continuously, so your home is always ventilated with fresh, pre-warmed air.

The result? A reliable, energy-efficient ventilation system that protects against black mould, damp, and condensation—all while saving energy and recovering heat that would otherwise be wasted by traditional extractor fans.

Fan Speed: Two ventilation modes — Low (trickle) and High (boost) — ideal for maintaining healthy airflow and providing damp control ventilation in areas affected by condensation or mould.

Airflow: Delivers up to 45 m³/hour (13 l/s) of air — suitable for smaller rooms that need higher levels of indoor air quality and better air exchange, to help prevent damp build-up and mould.

Heat Recovery: Up to 75% heat recovery efficiency. Helps retain warmth while ventilating spaces prone to humidity, reducing the risk of mould growth.

Noise level: Operates at just 21 dB from 3 metres — near-silent performance, even when running continuously.

Power Use: Extremely low energy use at just 2.4 watts — efficient and cost-effective for long-term use.

Efficiency: Consumes only 0.49 watts per litre of air moved per second, helping to keep energy bills low.
