Sheet metal supporting frame and double shell curtain
panels externally pre-painted, fully removable with average
20 mm thick internal thermal and acoustic insulation.
High efficiency aluminium plate heat recovery, Eurovent
certified, of static type with airflows separated by special
seals.
G4 efficiency class air filters, easily removable from every
side (bottom, side, top) allowing their periodic cleaning; as an
option, M6-F7-F8 efficiency class filters are available.
Fan sections consisting of double suction front blades
centrifugal fans directly coupled to single-phase
electronically-controlled Brushless EC.
The unit is complete with electronic control panel.
Galvanized steel condensate drain tray, with discharge from
the bottom side.
