Condensate connection on the underside of the unit, delivery includes ball siphon. Connection to drain pipe on site. Two low-noise high-performance centrifugal fans with energy-saving EC motors for extract and supply air ducting. Heat recovery by means of highly efficient, large-area enthalpy heat exchanger for heat and moisture recovery made of polymer membrane foil. Automatic summer bypass incl. heat exchanger cover. Filter equipment: ISO Coarse 65% (G4) filter for fresh air and extract air as standard; an ISO ePM1 50% (F7) fine filter is available as an option, which can also be integrated into the unit.
