SKU: TOTUS2 Category:


  • MINI and MIDI Models are manufactured with a frameless construction from single skinned Aluzinc panels, internally lined with 90kg/m3 high efficiency acoustic and thermally insulating foam.
  • MAXI units are manufactured with an aluminum frame construction with double skinned Aluzinc panels fitted with 60kg/m3 thermal acoustic insulation
  • The casing includes an inclined inlet and bell mouth entry which directs the incoming air to the impeller with minimal turbulence. The result is better air management through the unit, less noise, higher efficiency and an increased performance.
