The REC Duo 150 is an innovative air extraction and supply unit with high-efficiency (90%) heat recovery, designed to be installed in pairs in a single room or in two separate spaces.
Extremely simple and fast installation:
– minimal masonry work: only a 150 mm hole in the perimeter wall is required.
– magnetic attachment/detachment of the fan unit
– “inside-out” type external grille, installable from the inside
– telescopic pipe
The REC Duo 150 operates on the so-called “push-pull” principle, i.e., with alternating flow and a 60-second flow reversal cycle. It is equipped with a ceramic regenerative heat exchanger that stores the heat of the extracted air during the extraction cycle (pull) and then releases it to the supply air during the supply cycle (push).
It is designed for continuous operation (24h) at minimum speed. Switching to maximum speed is done either by manual user intervention (remote button/switch – not supplied, or RLS control available as an accessory) or automatically via a humidistat for the REC Duo MHY and REC Duo RC versions.
