Waterproof Cooling Fan blower has what characteristic?

⒈ "Waterproof Cooling Fan" blower impeller in the body due to friction-free operation, no lubrication, so that the exhaust gas is not oil. Chemical, food and other industries ideal for pneumatic conveying gas source.
⒉ blower case of displacement blower operation. When used, along with changes in pressure, flow rate variation is very small. But the flow varies with speed. Therefore, the choice of a wide range of pressures, the flow rate can be selected by selecting the rotational speed to achieve the requirements.
Higher ⒊ "Waterproof Cooling Fan" blower speed, the small gap between the rotor and the rotor, between the rotor and the body, and thus less leakage, high volumetric efficiency.
⒋ blower structure to determine its mechanical friction loss is very small. Because only the bearings and gears deputy have mechanical contact in the selection, rotors, chassis and gear ring has sufficient mechanical strength. Operational safety and long service life is a major feature of blower products.
⒌ blower rotor, have been static and dynamic balance check. Finished smooth, vibration is minimal.
⒍ with the above characteristics of "Waterproof Cooling Fan" blower are: Roots blower, side channel blower, multistage centrifugal blowers
