Products Description

Product Features

1. Water-Injected Screw Element
Engineered for ultimate energy efficiency, our water-injected screw element leverages low operating temperatures to minimize energy loss. Featuring water-lubricated, grease-free bearings and an in-house designed screw profile, it delivers exceptional durability with a working pressure of up to 13 bar—perfect for demanding industrial applications.

2. Water Filter
Say goodbye to inconsistent water quality. Our high-performance water filter ensures a steady supply of clean water, maintaining a consistent 10-micron filtration efficiency throughout its entire lifespan. No degradation, no surprises—just reliable purity when you need it most.

3. Heavy-Duty Air Filter
Protect your compressor’s critical components with our heavy-duty air filter, which captures 99.9% of dirt particles as small as 3 microns. Equipped with differential inlet pressure monitoring, it enables proactive maintenance while minimizing pressure drop, ensuring uncompromised performance and longevity.

4. Separator Vessel
Crafted from corrosion-resistant stainless steel, our separator vessel uses centrifugal force and gravity to efficiently separate water from compressed air. Three integrated sensors provide precise water level regulation, preventing carry-over and ensuring stable operation even under variable loads.

5. Induction Motor
Experience unrivaled energy efficiency with our IP55-rated induction motor, flange-mounted for perfect alignment and paired with a direct-drive arrangement. This eliminates energy loss from belts or gears, delivering maximum power transfer and reducing long-term operating costs.

6. Reverse Osmosis System
Achieve operational autonomy with a built-in reverse osmosis system that produces a continuous supply of high-purity water. No need for external water treatment—our system ensures reliable, on-demand water quality to keep your compressor running smoothly, 24/7.

7. Air-Cooled Fan & Water-Cooler
Choose the cooling solution that fits your space: our range includes both air-cooled and water-cooled variants, all with compact footprints thanks to integrated heat exchangers. Water-cooled models maintain a consistent dryer inlet temperature below 55°C (131°F), optimizing downstream air treatment efficiency.

8. Integrated Highly Efficient Dryer
Redefine air quality with our integrated dryer, which delivers class-leading performance while cutting energy consumption by 50% compared to traditional dryers. Plus, its ozone-depletion-free design aligns with global sustainability goals, making it an eco-friendly choice for your operations.

9. Elektronikon® Graphic Control System
Take control with the advanced Elektronikon® Graphic system, designed for seamless integration into remote or local process control networks. Real-time monitoring, predictive maintenance alerts, and intuitive diagnostics ensure your compressor operates at peak performance, with minimal downtime.

10. Sound-Insulated Canopy
Save space and costs with our sound-insulated canopy, which eliminates the need for a dedicated compressor room. Engineered to reduce noise emissions to industry-leading levels, it can be installed directly in production areas, warehouses, or other working environments without disrupting operations.

11. Electronic No-Loss Water Drain
Ensure hassle-free condensate removal with our electronic no-loss drain, which automatically purges condensate without wasting compressed air. A built-in manual bypass guarantees operation even during power outages, while integration with the Elektronikon® system provides real-time warnings and alarms for proactive maintenance.
