BEKO
BEKO TECHNOLOGIES of Neuss, Germany, was founded by Berthold Koch in 1982 and is still an independent family business with quality management to EN ISO 9001:2015. It specialises in compressed air condensate: it makes BEKOMAT condensate drains, ÖWAMAT separators and BEKOSPLIT emulsion splitting units.
From BEKO we offer the ÖWAMAT 10 and 11 oil-water separators and the matching OEKOSORB filter sets. The separator removes oil from the condensate without electricity, purely by gravity, and the water flowing out contains no more than 20 mg/l of oil. You then only dispose of the used filter element, not all the condensate.
Manual in CzechÖWAMAT separators and filter sets
ÖWAMAT 10 — up to 2.4 m³/min
For smaller compressors. A separator with a 10 l container that handles up to 2.95 l of condensate per hour.
- compressors from 1.4 to 2.4 m³/min
- height 528 mm, weight 3.5 kg
- replacement filter set O10
ÖWAMAT 11 — up to 4.9 m³/min
The indicator shows when to change the element. A larger separator with an 18.6 l container that handles up to 6 l of condensate per hour.
- compressors from 2.8 to 4.9 m³/min
- height 604 mm, weight 5.75 kg
- replacement filter set O11
O10 filter set
Replacement element for the ÖWAMAT 10. Two-stage OEKOSORB filter element and filter mat.
- prefilter 2.5 l, main filter 2.6 l
- retains up to 0.6 kg of oil
- BEKO material no. 4010719
O11 filter set
Replacement element for the ÖWAMAT 11. Two-stage OEKOSORB filter element and filter mat.
- prefilter 4.7 l, main filter 4.8 l
- retains up to 1.8 kg of oil
- BEKO material no. 4011999
O12 filter set
For existing ÖWAMAT 12 units. The ÖWAMAT 12 is no longer made, but BEKO still supplies filter sets for it.
- prefilter 2.5 l, main filter 5.9 l
- filter mat 120 × 50 × 30 mm
- for units with and without pre-separation
Is your compressor below 1.4 or above 4.9 m³/min? WOSM separators for small and WOS for large compressors are in the same category as ÖWAMAT.

Capacity and element service life apply to the manufacturer’s reference conditions: 30 °C, 70 % relative humidity, 7 bar. In warm, humid surroundings more condensate forms, so the separator can only handle a smaller compressor.
How to install and maintain an ÖWAMAT separator
1. Choose the size
Add up the capacity of all compressors whose condensate will flow into the separator. The ÖWAMAT 10 is enough up to 2.4 m³/min, the ÖWAMAT 11 up to 4.9 m³/min.
2. Connect
Install the separator indoors, protected from frost and sunlight. Feed the condensate through up to two G½ inlets, ideally from level-controlled condensate drains.
3. Fill with water
Before first start-up, fill the separator with clean tap water. The purified water then drains by gravity.
4. Check and replace
Once a week, compare a water sample with the turbidity tube. Replace the element when the sample is cloudier, when the ÖWAMAT 11 indicator shows it, or after 12 months at the latest.
Frequently asked questions
- Does the ÖWAMAT need electricity?
- No. The condensate flows through by gravity. Only the optional ÖWAMAT 11 accessories need electricity – the alarm sensor for the level indicator and the frost protection heating.
- How do I know the filter element is exhausted?
- From the turbidity test: compare a sample from the service valve with the reference tube supplied with the separator. If it is more turbid, replace the element. The ÖWAMAT 11 also shows this on its level indicator. Replace the element after 12 months at the latest.
- May I discharge the purified water into the sewer?
- ÖWAMAT purifies the condensate to an oil content of no more than 20 mg/l and has the German DIBt approval Z-83.5-9. Whether you may discharge the water is decided by the sewer operator or by local regulations – please check this.
- Can the ÖWAMAT handle any condensate?
- Only compressor condensate in which the oil is dispersed. It cannot separate a stable emulsion – milky condensate that does not separate even after a long time. With synthetic oils the capacity may differ; the manufacturer recommends having a condensate sample tested.
- Can I still get filter sets for an older ÖWAMAT 12?
- Yes. The manufacturer stopped making the ÖWAMAT 12 in September 2023 but still supplies filter sets for it. The O12 set fits the ÖWAMAT 12 with and without pre-separation.
- What comes with the separator?
- The separator with the OEKOSORB filter element fitted, the reference turbidity tube, a wall bracket with fixing material and the installation and operating manual.
A Czech technical data sheet is available for download with every product, and the ÖWAMAT 10 and 11 separators and the O10 and O11 sets also come with the manufacturer’s manual in Czech. The O12 set comes with the ÖWAMAT 12–16 manual in German, English, French and Dutch. BEKO®, ÖWAMAT®, OEKOSORB®, BEKOMAT® and BEKOSPLIT® are registered trademarks of BEKO TECHNOLOGIES GmbH.
