Maintenance-Free Direct-Drive + Intelligent Electronic Control: 90 kW Industrial Screw Air Compressor—Peace of Mind, Energy Savings, and Cost Efficiency
The AIRERA 90 kW industrial screw air compressor serves as the high-capacity power heart for heavy-industry manufacturing. Utilizing premium integrated direct-drive technology, it delivers 100% rigid power transmission—completely eliminating belt slippage and downtime under high torque for a lifetime maintenance-free drivetrain. Paired with an intelligent electronic control system, it dynamically responds to massive plant-wide air fluctuations, eliminating wasteful unloading energy. Built to conquer high-power energy consumption, it is the ultimate smart asset for modern large-scale enterprises driving toward aggressive cost reduction and sustainable low-carbon production.
-
High-efficient motor
Reach European IE-3 standard & Australian MEPS standard.IP 55 protection standard in SF1.2.With self-cooling fan for high ambient temperature.Stable and reliable.
- Air end
Higher efficiency than single stage(>15-30%),bigger air flow,low noisy,power saving,reduce exhaust temperature and improve the volumetric efficiency of the compressor.It can make the gas force smaller and more uniform.
- Fan motor
Motor IP class : IP44;Motor without self cooled function;Motor without service factor;Low cooling air flow;Lower cooling air pressure.

At this heavy-duty tier, component wear is heavily influenced by oil quality and bearing design. AIRERA utilizes heavy-duty SKF bearings specifically rated for high torsional loads, coupled with a high-precision internal oil piping network. The intelligent controller includes a pre-lubrication startup routine and monitors oil filter pressure drops. This prevents dry-friction wear during startups and guarantees that the large screw rotors are perfectly sealed and cooled, extending the core maintenance intervals.
