Compact air handling units
from 400 to 7.400 m³/h

The frame, pre-painted, is made from steel profiles and the panels are sandwich type (double shell), internally insulated with sound-proof material (10 mm thick. for 10 to 40 models, 20 mm thick for 50 and 60 models).
The panels are made of pre-painted sheet metal, fixed to the frame with screws and equipped with seals.
The base filtering section is composed of G4 efficiency class synthetic cell filter.
The water heat exchangers are made with copper tubes and aluminium fins.
The galvanized steel condensate drain tray is easily removable from the bottom without disassembling the unit.
The fans are double inlet forward-curved blades centrifugal type with 3-speed direct driven motors.
The electronic control panel is supplied entirely cabled and fitted with a relay board to control the fan input power.

The table lists the sound power values (SWL) in octave bands and totals; it also indicates the values of sound pressure level (SPL) at 1 m, 5 m and 10 m at supply, return and at the outside of the unit. All values refer to the operation of the ducted unit at FULL speed and at the nominal flow rate.
