Location: Cacouna, Rivière-du-Loup Regional County Municipality within the Bas-Saint-Laurent region of Québec, Canada.

Application: Administrative Building of the Wolastoqiyik Wahsipekuk First Nation.

Unit installed: BlauAIR RV3500E floor-mounted heat recovery unit.


We are proud to see our Blauberg BlauAIR RV3500E unit installed as part of the HVAC system in the Administrative Building of the Wolastoqiyik Wahsipekuk First Nation in Cacouna, Québec.

This meaningful project, located near the St. Lawrence River, combines modern engineering solutions with a strong sense of place and community identity.

Our BlauAIR RV3500E air exchanger contributes to reliable ventilation, efficient heat recovery, and long-term indoor comfort within this important political and administrative facility.

Advantages of the BlauAIR RV3500E include:

  • high air flow – the maximum air flow is 2060 CFM (3500 m3/h);
  • vertical air discharge – lower risk of recirculation, no facade contamination;
  • rotary heat exchanger – higher energy recovery efficiency and no icing issues;
  • low noise level – ~1.6 Sones (35 dBA) at a distance of 10 ft (3 m);
  • low power consumption – thanks to the use of EC motors;
  • high-quality air filtration – thanks to the MERV 13 supply air filter.


Projects like this highlight the value of sustainable HVAC solutions that serve communities and support resilient infrastructure.
