The air distribution grill is made of plastic.
Filter. A replaceable filter with polypropylene cells and a galvanized steel frame. Easy to replace thanks to special plastic guides.
Fan. A centrifugal fan with an aluminium or plastic impeller, statically and dynamically balanced to run as quietly as possible.

Сasing

Motor. A six-speed single-phase motor (with three factory-set speeds), mounted on anti-vibration supports and equipped with an auto resettable thermal switch, with protection rating IP20, insulation class B.
Heat exchangers. The heat exchangers are made of copper pipes with aluminium fins. The main heat exchanger is avail- able in a 4-row version. The heat exchanger is connected on the left side as a standard. Units with right-side connection are available on request.
Drainage pan. The pan is made of plastic and insulated with polyolefin foam (class M1); the pipe is 15 mm in diameter.
