Blauberg Envira 50 Single Room Alternate Flow Heat Recovery Fan for Mould Control | ENVIRA-50

The Blauberg Envira 50 Single Room Alternate Flow Heat Recovery Fan is a powerful, energy-efficient ventilation system designed to tackle mould, damp, and condensation while recovering up to 75% of lost heat. Built for both new builds and retrofit projects, the Envira 50 delivers fresh, filtered air to your home without the heat loss associated with standard extractor fans — making it an ideal solution for homeowners, landlords, and housing providers.

Using advanced alternate flow heat recovery technology, the Envira 50 continuously cycles between extract and intake modes every 60 seconds. During extraction, warm, humid air is drawn out and passed through a high-efficiency ceramic heat exchanger that captures the heat energy. Then, in the intake phase, fresh outdoor air passes through the same core, absorbing that stored warmth before entering your room. The result is a constant supply of fresh air — pre-warmed, filtered, and balanced — with minimal energy use.

With near-silent operation at just 16 dB(A), automatic humidity sensing, and remote-control convenience, this sleek wall-mounted fan provides hands-free protection against black mould, damp, and condensation, all while reducing heating costs.

The Blauberg Envira 50 is fully compliant with Building Regulations Part F and Part L and supports Awaab’s Law, making it a trusted choice for landlords and social housing providers seeking long-term, tamper-proof ventilation solutions.
