MIA-ANS3B-30

Cylindrical rotor alternates between supply and exhaust cycles — one half recovers heat from outgoing air while the other supplies fresh pre-conditioned air. No separate supply and exhaust fans required. Single fan bidirectional switching.

Requires only a single Ø200 mm core-drill hole through the exterior wall. No ductwork, no ceiling work, no building permit in most jurisdictions. Fits walls 100–400 mm thick — covers most masonry and concrete construction.

Washable foam pre-filter on indoor face — rinse every 3 months. Rotating core self-purges condensate during exhaust cycle. No annual service required for 5+ years of normal operation.
