MWOS Series Oil-Water Separator

Compressed air is often called the fourth utility after water, gas, and electricity. But while it is essential, it also produces a harmful byproduct: compressor condensate—a mixture of water, oil, and contaminants. Just one liter of oil can pollute one million liters of water, which is why most countries strictly regulate how condensate may be discharged. Directly draining untreated condensate into sewer systems is both illegal and environmentally damaging.
 
The MWOS Series Oil-Water Separators provide a reliable, cost-effective solution to this problem. Using state-of-the-art multi-stage separation and absorption technology, MWOS units reduce oil content in compressor condensate from 3,000–500 ppm down to below 10 ppm, meeting ISO 14000 environmental standards. This allows safe and compliant drainage into sewer systems while protecting both your facility and the environment.
 
Key Features & Benefits
Environmentally Responsible – Reduces oil concentration in condensate to <10 ppm, meeting international discharge regulations.
Eco-Friendly Design – Low carbon footprint with sustainable operation.
Reliable Performance – Advanced Mikro-Sep, Mikro-X-Tex, and Mikro-Carb filtration stages ensure maximum oil removal.
Low Maintenance – User-friendly installation and service minimize downtime.
Durability & Protection – Wear-resistant multiple inlet ports and built-in filter system prevent contamination from particles.
Visual Monitoring – Flow overload indicator provides at-a-glance system status.
Safe Oil Collection – Select models include an oil storage box that complies with environmental oil collection regulations.
Flexible Compatibility – Works with both mineral and synthetic oils across a wide range of compressor systems.
 
Available Models
MWOS-11 – Compact, single-use design; ideal for smaller systems.
MWOS-37 & MWOS-55 – Multi-stage separation with oil collection box; suited for medium-capacity compressors.
MWOS-110, MWOS-160, MWOS-200, MWOS-250 – Larger models designed for high-capacity compressed air systems.
 
Technical Highlights
Outlet Oil Concentration: <10 ppm
Multiple sizes available for compressor capacities from 1 to 33 cfm and beyond

Applications
MWOS Oil/Water Separators are ideal for use in:
Manufacturing facilities
Automotive and body shops
Food and beverage processing plants
Pharmaceutical and chemical industries
Any operation where compressed air systems generate oil-contaminated condensate
 
Working Principle
MWOS units process condensate through a step-by-step separation system:
Depressurization chamber protects separator from high pressure.
Mikro-Sep element removes the majority of oil.
Density separation allows oil to rise and drain safely.
Mikro-X-Tex media reduces remaining oil content.
Mikro-Carb granules polish the water to achieve <10 ppm oil concentration.
Purified water is safely discharged into drains, fully compliant with legal standards.
