AIRERA 37kW Screw Air Compressor: Frequently Asked Questions (FAQ)
Is AIRERA's 50HP compressor suitable for continuous 24/7 operation?
Absolutely. With high-grade components and a heavy-duty cooling design, the AIRERA 50HP unit is built for continuous industrial duty, maintaining stable discharge pressure and temperature even under full load.
How does AIRERA ensure the durability of the rotors without oil lubrication?
Our rotors feature a special aerospace-grade coating and precision clearance design. This prevents metal-to-metal contact and corrosion, ensuring the screw hosts maintain high efficiency and a long service life even without oil.
What about the noise level of a 50HP direct-driven unit?

Thanks to the direct-drive precision and our fully enclosed sound-dampening cabinet, the noise level is significantly lower than gear-driven competitors. It creates a much more comfortable and safer working environment for your staff.
