Industry-leading air host
The air compression chamber is completely separated from the oil chamber. The air side adopts a non-abrasive sealing system with a spring-loaded metal ring, and the lubricating oil side adopts a non-abrasive sealing system with a copper labyrinth seal. The two do not contact.
- Independent air intake system
Independent air intake ensures that the intake air temperature is equal to the ambient temperature. Large-capacity air filter is used to achieve better filtering effect, lower intake pressure loss, and energy saving and high efficiency. Maintenance and replacement are more convenient.

Air consumption in large-scale industrial workshops typically fluctuates drastically with different production processes. Fixed-speed machinery can only enter a high-energy "unloading" state during low-demand valleys, wasting electricity for nothing. Conversely, the AIRERA 75 kW VSD system tracks real-time line pressure fluctuations and precisely reduces motor speed during low-demand periods to produce air strictly on demand. This flexibility ensures the equipment always operates within its optimal efficiency range, eliminating the severe power wastage caused by traditional unloading.
When traditional high-power 75 kW compressors start directly or via star-delta starters, they generate a massive surge current up to 4 to 7 times the rated current, causing severe fluctuations in the factory's internal power grid and exerting immense mechanical shocks on gears and couplings. The VSD system achieves a "zero-surge soft start" through smooth adjustments from low to high frequencies, keeping the startup current strictly within the rated current, which effectively protects the workshop's power distribution system and vastly extends the service life of the mechanical drive train.
