Water-Lubricated Screw Compressor

Zero Oil, Zero Contamination, and Maximum Reliability

Most screw compressors rely on oil for sealing and cooling – which means you constantly worry about oil carry‑over, filter replacements, and product contamination. 

Not this one. Our water‑lubricated design uses nothing but clean water between the rotors. No oil in the compression chamber, no oil in your air lines. That makes it the natural choice for pharmaceutical, food, electronics, and any plant where pure, Class 0 certified air is a must. Water also removes heat more efficiently, so the compressor runs cooler and quieter. And because there are no oil separators to change, maintenance is simpler and cleaner. 

For 24/7 critical production, this is the compressor that gives you peace of mind – and pure air, every second of the day.

Frequently Asked Questions

What is a nitrogen generator, and how does it work?

A nitrogen generator is a device that produces nitrogen gas (N₂) from compressed air. It uses separation methods, such as Pressure Swing Adsorption (PSA) and Membrane Technology, to remove oxygen and other gases, leaving purified nitrogen gas.

What are the advantages of having a nitrogen generator over purchasing bottled nitrogen?

Cost savings: Long-term savings are achieved by eliminating the recurring costs of purchasing bottled nitrogen.

Convenience: Continuous on-site nitrogen generation eliminates the need for deliveries and reduces the risk of running out of nitrogen.

Customization: On-demand nitrogen generation allows you to tailor the flow and purity to your needs.

What is the difference between PSA and membrane nitrogen generators?

PSA (Pressure Swing Adsorption): Uses carbon molecular sieves to separate nitrogen from other gases in compressed air under varying pressure.

Membrane Technology: This technology uses selective permeable membranes to separate nitrogen from oxygen based on the size of the molecules.
