To reduce noise resulting from operation of the fan may be used noise suppressor. Suppersor's
casing is made of galvanized steel sheet, while the suppresor's core is made of perforated galvanized
steel sheet, with filling (insulation) made of acoustic mineral wool. Flexible connections are used to
eliminate vibrations transmitted by the fan to the ventilation system. For improved system operation
safety, it is recommended to protect the flexible connections (for outdoors installations) against birds
with a grille or a one-sided metal plate.
For vertical installation of the air supply unit outdoors, the unit is placed on the base/roof curb,
and the discharge side is connected to the air supply system. The suction side is protected against
weather conditions with mcr LAM louver vents (Fig. 13). The declared properties and features of LAM
vent (e.g. snow load SL 1300, wind load WL 1500) guarantee operation in extreme weather conditions.
For vertical installation indoors, the unit is mounted on the supporting structure and connected
to the air supply system in accordance with the design requirements.
mcr EXI-F air supply units include multi-blade dampers with actuator. The rotary mechanism of
the damper include gears and bearings or steel rods.
