Low noise blower fan with high speed and safe operation

- Jul 05, 2019-

The low noise blower fan is mainly used in the process of operation because the impeller runs without friction in the machine body, and does not require lubrication during operation, so that the discharged gas does not contain oil. It is an ideal pneumatic conveying source for chemical and food industries. The blower is a volume operated blower. When used, the flow changes very little as the pressure changes. But the flow varies with the speed. Therefore, the choice of pressure is wide, and the choice of flow can be achieved by selecting the speed.


The low-noise blower has a higher rotational speed during operation, and the gap between the rotor and the rotor and the rotor and the body is small, so that the leakage is small, the volumetric efficiency is high in use, and the structure of the blower determines that the mechanical friction loss is very small. Because only the bearing and gear pair have mechanical contact on the material selection, the rotor, casing and gear ring have sufficient mechanical strength. Safe operation and long service life are a major feature of blower products.


The rotor of the low noise blower is static and dynamic balanced. The finished product runs smoothly and the vibration is extremely small. The blowers with the above characteristics mainly include: Roots blower, side flow fan, multistage centrifugal blower
