Group rotary OIL-FREE Tooth air compressor
Setting the standard in energy efficiency, safety and reliability
The shortest route to superior productivity is to minimize operational cost while maintaining an uninterrupted supply of the right quality of air. The Group LUF 15- 45 compressor series is focused on effectively saving energy, ensuring product safety and guaranteeing the utmost reliability around the clock. And not just today, but day after day, year after year, with minimal maintenance cost, few service interventions and long overhaul intervals.
Pioneering the development of Oil-Free air technology
For over 60 years Group has pioneered the development of oil-free air technology. Resulting in the largest range of air compressors and blowers within our industry. Through continuous research and development, we achieved a new milestone, setting the standard for air purity as the first manufacturer to be awarded ISO 8573-1 CLASS 0 certification. CLASS 0 certification means zero risk of oil contamination from our products.
Technical Data:
First in ISO 8573-1 (2010) CLASS 0
With Group, you eliminate the risk of oil contamination from the compressor. Why risk damaged or unsafe products, losses from operational downtime or jeopardizing your company’s well-earned reputation? When tested across a range of temperatures and pressures, no traces of oil were found in the output air stream from our products, our compressors and blowers even surpassed TÜV’s stringent standards.

Flowcharts
Process flow, oil flow and cooling flow – step by step
The air is drawn into the compressor through the inlet filter where the air is cleaned. Next, it passes through the throttle valve with an integrated blow-off valve that takes care of the load / unload regulation. The air then continues to the compression stage.
In the first compression stage, the air pressure is raised to the intermediate pressure after which the air is cooled down in the intercooler. After the intercooler, the air passes through a moisture separation system before entering the high-pressure stage.
In the high-pressure stage, the pressure is brought to the final pressure. The air at the outlet of the high-pressure stage goes via the pulsation damper with an integrated check valve to the aftercooler where it is cooled down and moisture is separated and evacuated. The compressed air leaves the compressor through the outlet connection flange.
The yellow flow is the oil path within the compressor, where the oil pump sucks oil from the oil sump and pumps it through the oil cooler and the high-efficiency filter giving cool clean oil to the bearings, the gears, and the compressor’s element jackets. It is important to note that in the complete process, no oil comes in contact with the Air, hence ensuring complete oil-free air.
