Dry Screw Compressor

No oil enters the compression chamber - structurally, not as a downstream fix. That is the starting point of this dry screw compressor, which delivers Class 0 air through Teflon-coated rotors and contact-free timing gears. The rotor surfaces carry a special Teflon layer that provides oil-free sealing and wear resistance, and synchronized timing gears keep the two rotors in phase without any contact or friction between them. Compression temperatures stay low, which keeps rotor thermal deformation small and protects the coating over long hours. Because no oil enters the air path, the machine delivers Class 0 air and removes oil-changing and waste-oil disposal from the maintenance list, while producing no waste oil at all. The absence of oil also simplifies documentation for quality-audited plants, since there is no oil carry-over parameter to monitor. The package is compact, reliable and lower in running cost than buyers expect from an oil-free machine. The platform covers 7.7 to 50.2 cubic meters per minute at 7 to 10 bar with 55 to 315 kW, suiting mid-size to large process air demands. The buyer logic is that for food, pharma, biotech, precision spray and electronics processes, oil contamination is a quality and compliance risk, and a true dry screw chamber eliminates that risk structurally instead of filtering it away downstream. With no oil system, the machine room also stays clean, with no risk of oil spills on the floor, and because the timing gears keep the rotors out of contact, there is no rotor wear from touching surfaces, which is why dry screw airends hold Class 0 performance over long service intervals.

Dry machines reward planned maintenance: coating condition, timing gear lubrication and seal condition decide how long Class 0 performance holds. Comps provides scheduled maintenance programs with on-site inspection, filter and lubrication servicing, transmission adjustment, electrical checks and parameter calibration. For the buyer, this keeps air quality certified over years rather than letting it drift after the warranty.

Applications

 

Food processing and pharmaceutical production. Class 0 air eliminates the risk of oil contact with products and packaging, which is the structural reason dry screw compression is mandated here.

Biotechnology and precision spraying. No oil aerosol protects sensitive cultures and coated surfaces from contamination.

Electronics, semiconductor and textile plants. Oil-free air avoids residue on boards, fibers and finished surfaces, and the wide flow range fits both line supply and central stations.
