Oil-Free Screw Air Compressor

7 photos

Two-stage oil-free screw compressors with no oil in the compression chamber. 55–260 kW, delivering oil-free clean compressed air for food, pharmaceutical, semiconductor, precision coating and other clean-air applications.

Clean compressed air with no oil carryover: oil-free screw compressors

An oil-free screw compressor uses no oil in the compression chamber, producing clean compressed air with no oil content.

It is widely used in industries that require clean compressed air, such as food, pharmaceuticals, semiconductors, printing, chemicals and precision coating.

  • Convenient operation with a touchscreen controller

  • Low noise thanks to a high-performance airend

  • High-precision components prevent oil ingress

  • Latest rotor and airend design maximizes energy efficiency

Key features

Airend for low- and high-pressure duty

The airend, with an optimized profile designed using precision machining technology, offers durability and high quality, delivering optimal performance for clean air production.

Airend

Efficient oil pump

A correctly sized oil pump not only suppresses oil circulation losses but also provides the ideal conditions for smooth compressor operation.

Oil pump

Cyclone water separator

A cyclone-type water separator removes moisture from the compressed air, extending airend life and providing optimal operating conditions.

Water separator

High-efficiency airfoil fan

A high-efficiency airfoil fan maximizes cooling efficiency and provides a stable cooling system with excellent noise and airflow characteristics.

Touchscreen controller

A large touchscreen LCD presents the compressor's operating status, protection functions and maintenance messages as icons for easy operation.
