That is why Westa Air Control extracts the used air right here. Simultaneously, the same amount of fresh and cleaned air streams into all of the other rooms without there being a draft. During this process the WAC central control unit ensures that the warmth of the exhaust air is carried onto the fresh and newly supplied air. The tube and conduit system, the mufflers, the machine technology and the high-performance heat recovery to save energy are the core elements of the Westaflex controlled household ventilation. The building components system ensures that on-site nothing is missing and that no time is lost during assembly. https://westaflex.com/logo.png
