negative pressure fan introduce

Fan frame :made from highly galvanized steel sheets in order to assure highest strength and strong resistance to corrosion .

Blade : 6piece stainless steel blades and the fan has all passed the experiment of homeostasis with big air volume,without deformation ,no breaking ,attractive and durable.

Belt pulley:the V type belt is aluminium magnesium alloy injection moulded ,light weight,high-stength

Some question and solution:

A. vacuum blower installed with the window frame window frame so that the resonance caused by tight contact, negative pressure fan operation.

Solution: stuffing between the window frame and the water air conditioning appropriate to reduce, and the application of the soft packing materials, uneven mounting bottom stability should be stable mat floor, placed smoothly, reliable.

B. vacuum blower installed adverse suction fan should be installed in a suspended state, can not be crushed foot bolt spring.

Solution: please repair personnel to adjust the negative pressure fan installation status, so that it is in a state of suspension.
