DC blowers are widely used in ventilation and fire-fighting high-temperature smoke exhaust in tunnels, underground garages, advanced civil buildings, metallurgy, factories and mines. Features of DC blower.

1. Since the impeller runs in the body without friction, it does not need lubrication, so that the discharged gas does not contain oil. It is an ideal pneumatic conveying gas source for chemical, food and other industries.

2. The blower is a volumetric operating blower. When in use, with the change of pressure, the flow rate changes very little. But flow varies with RPM. Therefore, the selection range of the pressure service is very wide, and the selection of the flow rate can be achieved by selecting the speed.

3. The speed of the blower is high, and the gap between the rotor and the rotor, between the rotor and the body is small, so that the leakage is less and the volumetric efficiency is high. The strong processing and assembly technology can ensure reasonable and uniform clearance, which can achieve high volumetric efficiency without causing friction in the body due to thermal expansion.

4. The structure of the blower determines that its 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 the major features of blower products.

5. The rotors of the blower are all checked for static and dynamic balance. The finished product runs smoothly with minimal vibration.
