ULTRA-COMPACT DESIGN
EASY MAINTENANCE
The new FDK models are characterised by a design that
minimises air flow resistance (CFD analysis), thus obtaining
uniform distribution throughout the environment to be
conditioned. The new slimmer design also offers easy and
precise installation in special logistical conditions.
Cleaning the unit is made easier by the opening/closing
mechanism of the front panel from above,
facilitating access to the removable filters.
