Product detailed description
The O11 kit is the original replacement OEKOSORB filter element kit for the ÖWAMAT 11 separator. The element has two stages – a prefilter and a main filter – and binds the oil from the condensate; the filter mat traps dirt above the element.

When to replace the element
Replace the element as soon as the first of these situations occurs:
- the turbidity test fails – the sample is more turbid than the reference tube
- on the ÖWAMAT 11, the red marking appears in the level indicator
- the calculated service life of the element, based on compressor operation, has elapsed
- after 12 months at the latest
How to replace the element
- shut off the condensate feed and take off the separator cover
- remove the filter mat and the pressure relief chamber with the feed pipe
- slowly pull the used element out of the container and allow it to drain
- place the element and the mat in the PE bag and hand them over for disposal as oil-contaminated waste
- clean the container, insert the new element and fit the pressure relief chamber
- fill the pressure relief chamber with tap water until water flows out of the drain; then insert the new filter mat, refit the cover and slowly open the condensate inlet
Checking the water
- once a week, take a water sample from the service valve and compare it with the reference turbidity tube
- the tube corresponds to 20 mg/l of oil; the manufacturer also supplies tubes for 10 and 5 mg/l
- record the result in the operating log and at the same time check that nothing has damaged the separator
- have expert maintenance carried out every 6 months; clean the container once a year and at every element replacement
The full range is in the ÖWAMAT separators category.

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

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.

- 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.
