Maintenance-Free Direct-Drive + Intelligent Electronic Control: 75 kW Industrial Screw Air Compressor—Peace of Mind, Energy Savings, and Cost Efficiency
The AIRERA 75 kW industrial screw air compressor is engineered for heavy-duty, high-capacity industrial demands. Featuring an advanced integrated direct-drive system, it eliminates the transmission losses and wear vulnerabilities of traditional belts or couplings, delivering a lifetime maintenance-free drivetrain. Equipped with an intelligent electronic control system, it precisely modulates frequency to match fluctuating factory air demands, eliminating energy waste from unloading. Delivering maximum uptime and peak energy efficiency, it is the ultimate solution for large-scale modern plants looking to slash operational costs and drive green transformation.

Cooling air flow
A separate generously sized cooling air fan provides several times the minimum required volume for the motors.The motor is sited in the main cooling air intake flow, which means:the coolest air crosses the motor first, increased service life.The ambient cooling air also cools the switch cabinet and the electrical components , which ensures:low component temperature and extended service life.
- 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.

Thanks to the inline integrated vertical or coaxial direct-drive layout, AIRERA has optimized internal space to the extreme, saving up to $20%$ of floor space compared to old-school belt-driven models. It arrives as a fully integrated "plug-and-play" skid. You only need to connect the main air piping and power cables to begin operation immediately, significantly cutting installation time and plumbing costs.
