The HAVA 400V is a mechanical ventilation and heat recovery unit delivering balanced supply and extract ventilation for dwelling applications. It features advanced EC brushless motor technology, a highly efficient counterflow heat exchanger to maximise thermal recovery, an LCD Display control unit with Modbus-enabled controls to enhance user comfort, simplify operation, and integrate seamlessly with wider building management systems.

The HAVA 400V is an ideal solution for improving indoor air quality, reducing CO₂ levels, and helping prevent condensation and mould, protecting both the building and occupant health.

Designed for vertical installation, with performance ideal for larger residential settings. The unit uses a high-efficiency heat exchanger to recover heat from the extract air, transferring this energy to the incoming air to maintain a comfortable indoor environment with reduced energy demand.

Quiet operation makes the HAVA 400V perfectly suited for installation in larger residential dwellings.

• LCD Display Multifunction controller, with tough buttons to select functionalities.
• Outer panels manufactured from powder coated galvanised sheet steel finished in white RAL 9010 with main internal body manufactured from EPP (expanded polypropylene) providing reduced sound emissions, maximised air tightness and thermal insulation.
  
• Backward curved centrifugal impellers are dynamically balanced and directly driven by the EC motors to provide a smooth airflow through the unit.
