Elegant buildings - reduced size, heating power and a modern look make the LEO FS heater an indispensable solution in medium-size facilities for official purposes such as: restaurants, pubs, shops, showrooms, etc.
Modern design - the housing, made of anti-static ABS plastic, fully covers and hides hydraulic and electric connections. An additional advantage is that the blades are made of anodized aluminium, as an aesthetic finishing element of the heater.
Efficiency - The M version of the air heater is equipped with a modern electronically commutated motor which needs only 57,5W. Additionally it is very quiet! It generates only 45dB(A).
Mixing chamber - there are two versions of the device available: The LEO FS – a heating apparatus and LEO KM FS – a heating - ventilating apparatus with a built-in mixing chamber hidden under the housing. Such a solution allows fresh and heated air to be supplied to the interior.
