Dry screw
Two-stage dry screw compression for continuous clean-air production without lubricating oil in the compression chamber.
ZSOIL-FREE AIR SYSTEMS
Oil-free air compressors for clean industrial processes.
Compare dry screw, water-lubricated screw, oil-free scroll and centrifugal technologies by flow, duty, site conditions and downstream air-quality requirements.
CHOOSE BY TECHNOLOGY
Oil-free is a requirement; the compression technology is the engineering choice.
The right platform depends on required flow and pressure, continuous or intermittent duty, noise and footprint limits, cooling conditions and the treatment needed at the point of use.
Water-lubricated screw
Water supports lubrication, cooling and sealing where clean compressed air and a compact screw platform are required.
ZWOil-free scroll
A compact, low-noise option for lower-flow applications, laboratories, healthcare and precision processes.
SSCentrifugal
A high-flow platform for large, continuous industrial air systems, available with conventional or magnetic-bearing configurations.
OIL-FREE PRODUCT RANGE
Five platforms for different clean-air duties.

SELECTION GUIDANCE
Define the air-quality target and operating point together.
A useful proposal needs required flow, working pressure, duty cycle, ambient conditions, cooling preference, power supply and the air-quality requirement at the point of use. Downstream drying and filtration remain part of system selection.
Contamination-sensitive production
Food, pharmaceutical, electronics and precision processes require the air system to be selected around the actual quality target and critical points of use.
Low-flow and low-noise duties
Scroll and compact technologies can fit laboratories, healthcare and precision equipment where footprint and acoustic limits matter.
High-flow continuous air
Centrifugal and dry-screw platforms support larger continuous systems when capacity, turndown, redundancy and site integration are evaluated together.
FAQ
Oil-free air compressor questions
What is an oil-free air compressor?
It is a compressor technology designed so lubricating oil is not introduced into the compression chamber or process air path. The exact architecture differs between dry screw, water-lubricated screw, scroll and centrifugal systems.
Which oil-free compressor technology should I choose?
Choose by required flow and pressure, load profile, available space, noise limit, cooling conditions and maintenance strategy. Dry screw and centrifugal platforms suit larger continuous demand, while scroll systems suit lower-flow, low-noise duties.
Does an oil-free compressor still need dryers and filters?
Often yes. Oil-free compression addresses the compressor air path, while moisture, particles and the required pressure dew point are managed by the complete treatment system selected for the process.
What information is needed for oil-free air compressor pricing?
Provide required flow, working pressure, operating hours, load changes, air-quality target, ambient and cooling conditions, electrical standard, redundancy requirement and the expected dryer, filter and installation scope.
