Since there is no metal-to-metal contact between the compression scrolls, no oil lubrication is required in the compression chambers. The working principle of the scroll compressor therefore guarantees high quality oil-free compressed air. The head of the scroll compressor is oil-free, so SLTOF series compressors are always oil-free air compressors.

Oil-free scroll compressors are very efficient. Due to the simple start/stop control, the loss of unloading power is eliminated. Using variable flow control technology, the compressor displacement can be matched to the air demand.

The low speed of the scroll components makes the SLTOF air compressor very quiet. Oil-free scroll air compressors are field-type compressed air systems that can be installed in any job location.

Oil-free scroll compressors stand for simplicity and reliability. Scroll air compressors are designed with minimal moving parts and can run for extended periods of time.

Oil-free compressed air is used in a variety of industries where air quality is extremely important for both the end product and the production process. These applications include food and beverage processing, pharmaceutical, chemical and petroleum, fermentation, sewage treatment, pneumatic conveying, non-woven textiles and other fields. In these critical applications, even the smallest oil contamination can lead to costly downtime, product contamination, product recalls and loss of reputation.
