FAN SECTION
Composed of one or two double inlet centrifugal fans with aluminium blades, mounted in horizontal position and statically and
dynamically balanced. The electric motor is fi tted with overload protection and has three speeds. It is constructed to comply with all
relevant International standards, with a capacitor permanently in circuit. Motors are connected directly to the fan shafts and are located
on anti-vibration mounts to ensure particularly quiet operation.
CHASSIS
The chassis is manufactured from thick (1mm) galvanised sheet steel.
COILS
Water Heat exchangers are copper tubes with aluminium fi ns, bonded to the tubes by a mechanical
expansion process. Coil connections are of female type antitorsion and headers are fi tted with easily
accessible air-vents.
CONTROL PANEL
Comfair HH fan coil units must be controlled from a separate remote controller. A large selection of controllers
with varying levels of function is available to satisfy most requests.
Options delivered separately : Ambient Thermostats (TA), Minimum water temperature thermostat (TC),
Remote (wall mounted) controllers (CD1, CD2/X1, ... ).
AIR FILTER
Simple to remove, it comprises a metal frame containing a washable acrylic fi lter media (fi ltration effi ciency EU 2).
