EcoAir Water-Lubricated, Oil-Free Compressor

Features of the Oil-Free Screw Air Compressor

Certified purity and lower operating cost

Water-based compression removes oil-related consumables and disposal from the operating budget, while the permanent magnet direct-drive motor with variable speed drive matches output to demand and reduces energy use.

Low maintenance and smart monitoring

Corrosion-resistant construction supports continuous 24/7 operation in demanding environments, and the optional IoT module gives operators real-time visibility into pressure, temperature, water quality, and energy usage. These characteristics together lower total cost of ownership while protecting the quality of air-dependent production lines.

Applications of the Water-Lubricated Oil-Free Compressor

Food & Beverage

Powers bottling lines, canning equipment, and packaging machinery with contamination-free air, supporting compliance with FDA, EU 10/2011, and other food-safety regulations to prevent product spoilage or health risks.

Pharmaceuticals

Supports sterile filling stations, bioreactor systems, and lyophilization equipment in ISO Class 5 cleanrooms, where air purity is critical for drug safety and efficacy during production and packaging.

Electronics

Provides dust-free compressed air for semiconductor assembly, circuit board manufacturing, and LCD panel production, preventing microchip defects caused by particulate contamination or oil residue.

Chemical Processing

Handles corrosive gas compression and pneumatic valve actuation in petrochemical plants, using stainless steel components to resist chemical erosion and maintain process integrity.

FAQ

What air purity class does the compressor achieve?

It delivers oil-free air to ISO 8573-1:2010 Class 0, with particle removal to 0.01 μm and residual oil content to 0.001 ppm, and carries TÜV Class 0 certification for critical applications.

What maintenance does the compressor require?

Maintenance is limited to annual water treatment to prevent scaling and filter replacement, with extended 10,000-hour service intervals that reduce downtime and operating cost.

What pressure and flow ranges are available?

Working pressure is adjustable from 8 to 10 bar, and free air delivery ranges from 1.10 m³/min to 42.6 m³/min, with motor powers from 7.5 kW to 250 kW across the model range.

How can energy consumption be reduced?

The direct-drive permanent magnet motor with variable speed drive adjusts output to real-time demand, reducing energy consumption by 30-40% compared with fixed-speed compressors.
