AIRERA 7.5kW Screw Air Compressor: Frequently Asked Questions (FAQ)
How does AIRERA define "100% Oil-Free" performance?
Through precision engineering and the use of advanced self-lubricating composite materials, the compression chamber remains entirely free of lubricating oil. This ensures that the output air meets Class 0 oil-free standards, making it ideal for industries with zero tolerance for oil contamination, such as medical, food processing, and precision laboratories.
Will the 7.5kW power output be too noisy for a small workshop?
Not at all. Thanks to the high-precision balance of the direct-drive transmission and AIRERA’s signature fully enclosed sound-dampening cabinet, the unit operates exceptionally smoothly. The noise level is significantly lower than traditional piston or belt-driven compressors, making it suitable for point-of-use installation without a dedicated machine room.
Is the daily maintenance for this machine complicated?

On the contrary, it is very simple. Because there is no oil system—meaning no oil changes, oil filters, or oil separators—and the direct-drive structure eliminates belt tensioning, maintenance is minimal. Users only need to periodically clean or replace the air intake filter and keep the cooler clean, saving substantial labor and consumable costs.
