Aerofresh 180


The Aerofresh 180 is a compact, energy-efficient HRV unit designed for small apartments or units that require a horizontally mounted, in-ceiling heat recovery system.

It provides a well-ventilated indoor space with simple and quiet operation while recovering thermal energy from wet rooms like kitchens and bathrooms that would otherwise be lost. This heat is transferred to the fresh, filtered supply air drawn in from outside. It is achieved by using a highly efficient counter-flow heat exchanger with up to 80% efficiency.

Filters are changed through a ceiling access panel and must be installed by the builder.
