　　The vacuum vortex air pump saves electricity, reduces energy consumption, saves costs, and achieves a power saving rate of over 20%. Improving the power factor of the power grid and saving on-site compensation devices can significantly increase the power factor of the power grid.

　　Performance advantages of vacuum vortex air pump:

　　1. Completely oil-free and compressed without water.

　　2. Reliable operation, sturdy and durable

　　3. Reliable design and lightweight

　　4. All motors of high-voltage fans have a protection level of IP55 and F-class insulation.

　　5. Adopting dual frequency (50/60HZ) and wide voltage motors to meet voltage levels in almost all regions of the world.

　　6. The external bearing design enables the fan to withstand high operating temperatures and improves its operational reliability and service life.

　　7. Introducing a new concept of variable frequency drive can improve the performance of the same model by up to 300% compared to using a regular motor drive.

　　The sealing form between the impeller and the pump body reduces the pressure loss of high-pressure gas during compression.
