A closer look inside the GAIRS single screw air end.

The single-screw design uses two symmetrically positioned star wheels to create balanced axial and radial forces on the main rotor.

Combined with low rubbing forces and hydrodynamic lubrication, this design contributes to high efficiency, durability, and reliable oil-free compression.

🌍 Rising energy costs. Unstable oil prices.
What if your compressor didn’t rely on oil at all?

Meet the heart of the compressed air technology:
GAIRS In-house Made Water Lubricated Single Screw Air End 💧⚙️

Instead of oil, water handles:
✔ Lubrication
✔ Sealing
✔ Cooling

Result?
🔹 100% Oil-Free Air
🔹 Lower operating noise
🔹 Higher efficiency with near-isothermal compression
🔹 Less vibration thanks to perfectly balanced symmetrical design
🔹 Longer-lasting performance at just 3,000 rpm

Why it matters:

Ever wondered how industry impacts our planet?

Compressed air is widely used across industries — but traditional systems often rely on oil, increasing the risk of pollution and energy waste.

GAIRS water-lubricated oil-free compressors offer a cleaner alternative:

✔ TÜV certified 100% oil-free air
✔ Lower compression temperature for higher efficiency
✔ Zero pollution discharge
✔ Reduced maintenance requirements

This Earth Day, it’s time to rethink how we generate compressed air.

Cleaner air for your industry.
Better future for our planet.

Innovation is in the details. 🔄

Meet the Gairs OGWYR Series – a water-lubricated compressor with an integrated air dryer. But here's the real breakthrough:
The dryer's own condensate is recycled to replenish the lubrication water.
✅ No external water source needed for top-up
✅ Higher water purity reduces scaling risk
✅ Lower operating cost – less waste, less maintenance
✅ Compact footprint – one machine, two functions
Smart engineering that saves space, saves money, and protects your compressor from within.

Ever wondered what you’re really breathing in a hospital?

In medical environments, compressed air is part of life support.
Even the smallest contamination is not acceptable.

That’s why medical air must be Class 0 oil-free.

With water-lubrication technology, our compressor delivers:
✔ 100% oil-free air purified by water
✔ Lower compression temperature
✔ Reduced contamination risk

Because clean air is not optional.
