Fan part

In a fan part for a ventilation or air-conditioning system comprising a pressure wall (20) and at least one fan (2) which penetrates through the pressure wall (20) and whose suction-side inlet (9) and pressure-side outlet (10) are situated in chambers (21, 22) separated from one another by the press...

Beschreibung
Zusammenfassung:	In a fan part for a ventilation or air-conditioning system comprising a pressure wall (20) and at least one fan (2) which penetrates through the pressure wall (20) and whose suction-side inlet (9) and pressure-side outlet (10) are situated in chambers (21, 22) separated from one another by the pressure wall (20), there being provided in the region of both sides of the pressure wall (20) in each case at least one pressure sensor (24 and 25, respectively) equipped with a manometer connection, the volume flow rate dependent upon the pressure difference can be simply and precisely determined by a manometer arrangement (30), connected to the pressure sensors (24, 25), cooperating with a display device (40) which has a pointer (43) movable in dependence on the measured pressure and a scale (45) which is provided on a scale carrier (44) constructed as a separate component and capable of being placed at the side and is calibrated to the volume flow rate at one fan speed.
