Envira-50 100mm Zone 1 Fan -100mm Blauberg
The ENVIRA-50 is a compact, high-performance alternate flow heat recovery fan engineered for single-room applications.
Designed to actively combat mould, extract stale air, and recover valuable heat, this unit ensures a fresh, healthy indoor environment all year round—with minimal energy use and ultra-quiet operation.
It’s ideal for bedrooms, living spaces, or retrofits where wall space is limited.
With smart humidity control and energy-saving EC technology, it works hard in the background so you don’t have to.
This compact system quietly manages humidity, prevents mould and damp, and recovers heat that would otherwise escape—delivering healthier air and lower energy bills year-round.
Can I change the speed? Yes — choose between Trickle for continuous background ventilation and Boost when humidity rises. It’s perfect for preventing condensation and mould.
How much air does it move? Up to 50 m³/h (14 l/s), making it ideal for bathrooms, bedrooms, and small living spaces where fresh air and moisture control are needed.
How much heat will it recover? Up to 75% of the heat from outgoing air is recovered—so rooms stay warmer while excess moisture is removed efficiently.
How loud is it? Just 16 dB at 3 metres—whisper-quiet even when running constantly. Suitable for night-time use and quiet rooms.
Does it cost much to run?Not at all. It uses just 2.3 watts—less than an LED bulb—so you can run it 24/7 without noticing a difference in your energy bill.
Whats the energy rating?: It’s highly efficient, with a Specific Fan Power of just 0.32 W/l/s—meaning powerful ventilation with minimal energy use.
