General features and technical data
Their quiet operation, compact dimensions and particularly low height, make units ideal for false ceiling
installation even in vintage buildings with narrow ceiling spaces. Units are standard supplied with sound
proofed suction plenum, air filter and extra-long drain pan. Centrifugal fans, with forwards curved blades, are
statically and dynamically balanced and moved by single-phase motor with three speeds (standard) plus one
(optional).
The availability of 2&4 pipe versions, the possibility to change connection side on field and accessories like
electronic thermostat and water on/
off valves, provides the maximum flexibility and ease of installation.
