Rotary blower air pressure range: 0.1-0.5 kgf/cm2
The rotary blower has an exquisite structure and is mainly composed of six parts: motor, air filter, blower main engine, air chamber, base (with oil tank), oil dripping nozzle
The blower operates on the eccentric rotor offset in the cylinder, it makes the volume change between the lobes in the rotor slot to suck in, compress, and discharge air
During operation, the pressure difference of the blower is used to automatically send the lubricating oil to the drip nozzle, drip into the cylinder to reduce friction and noise, and at the same time reduce the return of air in the cylinder
The rotary blower structure and stroke

The features:
. Low noise, low energy consumption, stable operation, easy installation
. Resistance to load changes, stable air flow, with air chamber for smooth air release
. Excellent materials, exquisite structure and outstanding performance
Applications:
- Water treatment aeration
- Hospitals and laboratories Sewage Mixing and aeration
- Vacuum paper feeding in the printing industry
- Electroplating tank and industrial water mixing and aeration
- Air supply for Plastic welding, blowing
- Burner spray, glass industry and others
