Description
The Blauberg Solo A35 S4 PRO R V.2 is a compact, cost-effective decentralised heat recovery ventilation unit designed for single-room applications and retrofit projects. Installed through a 106 mm wall duct, it uses a reversible EC fan and a high-efficiency ceramic heat exchanger to continuously introduce fresh filtered air while recovering heat from the extracted air.
Operating in alternating supply and extract cycles, the Solo A35 provides balanced ventilation with up to 75% heat recovery efficiency, helping to reduce heat loss, improve indoor air quality, and minimise condensation and damp. Its compact design makes it an ideal solution where installing a traditional ducted MVHR system is impractical.
With an integrated humidity sensor, low energy consumption, and whisper-quiet operation from just 21 dBA, the Solo A35 automatically responds to changes in indoor humidity to maintain a healthier and more comfortable living environment. It is an excellent choice for bedrooms, living rooms, apartments, home offices, and renovation projects.
