Product Description
AIRERA 75 kW Direct-Drive Intelligent Screw Air Compressor: Maintenance-Free, High Energy Savings & 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.

 CALT LGCD-75II Diesel Portable Compressor: Frequently Asked Questions (FAQ)
How does AIRERA 75 kW ensure the compressed air is clean and oil-free enough for sensitive production lines?
The AIRERA 75 kW features a high-efficiency, multi-stage oil and gas separation system. It utilizes a premium, oversized separation element that reduces residual oil mist to less than $3text{ ppm}$ (parts per million). Combined with our intelligent temperature control that prevents moisture condensation inside the system, it provides dry, high-purity compressed air that protects your downstream pneumatic components and high-end automated machinery from contamination.
High-power compressors are usually very noisy. How does AIRERA 75 kW perform in terms of noise control?
Despite its massive 75 kW capacity, the unit operates remarkably quietly (typically around $68 sim 72text{ dB(A)}$). This is achieved through three vectors: the inherently low vibration of the direct-drive system, a fully enclosed heavy-duty acoustic canopy, and localized sound-absorbing flame-retardant foam. It creates a much safer, more comfortable working environment for factory floors located near the compressor station.
Is the physical footprint large? How difficult is it to install?

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.
