5 Description
The casing is manufactured from seawater resistant aluminium. The base plate with nozzle consists of pre-galvanized
steel. Impellers with backward-curved blades are welded and galvanized (sizes 355 and 450 have impellers made of
pre-galvanized steel and tabbed). They are fastened together with hub and secured screw directly on to the motor
shaft. Dynamically balanced to ISO 1940 T1, class G6,3.
Serially equipped with B5 electric motor 3x400V~, 50Hz, IP 55, insulation class F, with built-in PTC. On request, the fan
can be equipped with electric motor intended for other voltage/frequency. Electric motor outside air stream is cooled
with fresh air. All sizes are serially equipped with service switch.
