1. Since the impeller runs frictionlessly in the machine body, no lubrication is required, so the discharged gas does not contain oil. It is an ideal pneumatic conveying gas source for chemical, food and other industries. The flow rate can be selected by selecting the speed to meet the needs.

3. The blower has a high speed, and the gaps between the rotors and the body are small, resulting in less leakage and higher volumetric efficiency. Our factory has strong processing and assembly technology, which can ensure that the gaps are reasonable and uniform, achieving higher 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 bearings and gear pairs have mechanical contact, the rotor, housing and gear ring have sufficient mechanical strength in material selection. Safe operation and long service life are the main features of our blower products.

5. The rotors of our blowers have been checked for static and dynamic balance. The finished products run smoothly with minimal vibration.
