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.

- Reliable protection against black mould, damp, and condensation.
- Ultra-quiet operation (21 dB), extremely low energy use (2.4 W).
