2 System overview
The SmartFan consists of acoustically optimised designer covers for inside (1) and out-
side(2)allowinganoptimalairow,alterunit(3),afanunit(4),aheatexchangerunit
(5) and an mounting tube (6). The SmartFan is always installed in an outside wall. The
mounting tube into which the fan and heat exchanger units are inserted is sealed inside
thewall.Theinsideandoutsidecoverscanbettedwithouttools.Theyconstitutethe
nishingelementsofthesystemandensureoptimalairow,therebyguaranteeingmore
efcientventilation.
2.1 Functioning
Wherever possible, SmartFans should be operated in pairs, i.e. with one unit blowing in
fresh air and the other expelling spent air. The units change direction concurrently after
50 - 70 seconds (depending on the selected fan speed). This allows a room to be properly
aired,balancingairinowandoutowinaccordancewithDIN1946-6.Theintegratedheat
exchangerextractsandstoresheatfromtheoutowingair.Whenthedirectionchanges
andfreshairissuckedin,itiswarmedbyowingovertheheatexchanger.Indoingso,the
SmartFan achieves a heat recovery rate of 91%.
