1. Introduction
This user manual provides essential information for the safe and efficient operation, installation, and maintenance of the BEKO ÖWAMAT 10 Oil-Water Separator. The ÖWAMAT 10 is designed to reliably separate oil from compressed air condensate, ensuring environmentally responsible disposal and compliance with regulations. By treating condensate on-site, you can significantly reduce disposal costs and environmental impact.
2. Safety Information
Always read and understand all safety instructions before installing, operating, or maintaining the BEKO ÖWAMAT 10. Failure to follow these instructions may result in serious injury or damage to the equipment.
- Ensure the unit is installed by qualified personnel in accordance with local regulations and standards.
- Always disconnect the power supply to the compressor before performing any maintenance on the separator.
- Wear appropriate personal protective equipment (PPE), such as gloves and eye protection, when handling condensate or performing maintenance.
- Do not modify the unit in any way. Use only genuine replacement parts.
- Dispose of separated oil and used filter materials according to local environmental regulations. Condensate contains oil and must be handled as waste.
3. Product Overview
The BEKO ÖWAMAT 10 is a reliable oil-water separation system designed for efficient treatment of compressed air condensate.
3.1 Key Features
- Conical Filter Intake: Facilitates easier filter changes and prevents bypass formation.
- Large Maintenance Opening: Ensures simple and convenient operation and servicing.
- Wall Mounting Capability: Allows for flexible installation options.
- Oleophilic Pre-filter: Effectively captures free oil components.
- Multiple Condensate Inlets: Supports connection of several condensate lines.
- Improved Filter Material: Offers higher performance than conventional activated carbon filters.
- Pressure Relief Chamber: Reduces overpressure and directs condensate smoothly to the pre-filter.
- Reliable System: Features official construction approval from the Institute for Building Technology, Berlin.

4. Setup and Installation
Proper installation is crucial for the optimal performance of your ÖWAMAT 10.
4.1 Mounting
- Select a suitable location for installation, preferably near the condensate source.
- The unit can be mounted on a wall. Ensure the mounting surface is stable and capable of supporting the unit's weight (approx. 3.67 kg, plus condensate).
- Allow sufficient space around the unit for maintenance and filter changes.
4.2 Connections
- Connect the condensate inlet lines to the two G 1/2" condensate inlets. The ÖWAMAT 10 supports multiple condensate supply lines.
- Connect the water outlet line to the G 1/2" water outlet. Ensure this line leads to an appropriate drainage system in compliance with local regulations.
- Ensure all connections are secure and leak-free.
5. Operating Principle
The BEKO ÖWAMAT 10 operates on a multi-stage separation principle to effectively remove oil from condensate.
- Pressure Relief: Condensate from the compressor first enters a pressure relief chamber, where any overpressure is safely dissipated. This ensures the condensate flows smoothly without turbulence.
- Pre-separation (Oleophilic Coalescing Pre-filter): The condensate then flows into an oleophilic coalescing pre-filter. This filter is designed to capture and separate free oil components from the water.
- Main Filtration: After passing through the pre-filter, the condensate enters the main filter. This filter adsorbs any remaining hydrocarbon components, ensuring the treated water meets discharge standards. The improved filter material provides superior performance compared to traditional activated carbon filters.
- Clean Water Discharge: The purified water is then discharged through the water outlet, ready for environmentally compliant disposal.
6. Maintenance
Regular maintenance is essential to ensure the long-term efficiency and reliability of your ÖWAMAT 10.
6.1 Filter Replacement
- The ÖWAMAT 10 features a conical filter intake, which simplifies the filter replacement process and prevents bypass formation.
- Filter life depends on the volume and quality of condensate. Monitor the unit's performance and replace filters as indicated by the unit or at recommended intervals (refer to specific filter instructions).
- To replace filters, open the large maintenance opening. Follow the specific instructions provided with the replacement filter kit.
- Always use genuine BEKO replacement filters to ensure optimal performance and system integrity.
6.2 Condensate Disposal
- The untreated condensate is considered waste and can contain oil components up to 10,000 mg/l.
- The ÖWAMAT 10 significantly reduces the oil content, making the treated water suitable for discharge into the public sewer system in many regions, subject to local regulations.
- The separated oil and used filter elements must be disposed of by a certified waste disposal company in accordance with all applicable environmental laws and regulations.
- On-site condensate treatment with the ÖWAMAT 10 is generally more cost-effective and environmentally friendly than costly disposal by specialized companies.
7. Troubleshooting
This section provides guidance for common issues you might encounter. For problems not listed here, please contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water not draining | Clogged outlet line or saturated filter. | Check outlet line for obstructions. Replace filters if saturated. |
| Oil detected in discharged water | Saturated filters (pre-filter or main filter). | Replace both the oleophilic pre-filter and the main filter. Ensure proper installation of new filters. |
| Condensate overflow | Blocked inlet or outlet, or excessive condensate volume. | Check all connections and lines for blockages. Verify the unit's capacity matches your compressor's output. |
