3 Product description
3.1 Product identification
To correctly identify the product when communicating with our service center, always have the informa-
tion from the product rating plate available.
3.1.1 Scope of delivery
●1 OME 40S Oil Mist Eliminator
●1 centering ring equipped with O-Ring DN40 ISO-KF
●1 quick connect clamp DN40 ISO-KF
●1 operating instructions
3.1.2 Function
The OME is mounted at the exhaust of a rotary vane pump and separates oil droplets and vapors from
gases emitted at the exhaust. Stopped by the filter element, they are transformed into liquid.
The OME must be mounted vertically above the pump, the condensed oil is recovered by flowing back
through the filter element into the oil case, if the inlet pressure is less than 1 hPa for a sufficiently long
time.
The OME has a safety valve set to 500 hPa relative pressure which prevents overpressure in the pump
oil case when the filter element is saturated. Do not allow solid or pasty deposits created by pumped
vapors to stick the valve to the filter element.
3.2 Storage
The filter elements inserted in the OME can absorb moisture.
If the new product must be stored:
►Store the product in a dry place in its original packaging.
►Store the product at storage temperatures (+5 – +65 °C).
►Make sure that the filter element is not crushed during storage.
Before using the OME, make sure that the valve is not stuck on the filter element.
If the product was unpacked, used, or stored for a long period (> 1 an) :
►Proceed to its maintenance by replacing the filter element (see « Maintenance » chapter).

4 Installation
WARNING
Poisonous substances exit from the exhaust
There is a poisoning hazard from discharged gases or vapors that can be hazardous and/or polluting
during use.
►Install and run the exhaust line so that overpressure cannot build up inside it.
►Follow the vacuum pump installation instructions in the respective operating instructions.
To allow the oil return in the pump oil case and avoiding all risk of seizing, it is mandatory to
take off the vent valve located at the exhaust port of the pump.
General instructions for installing the pump in the pumping line in accordance with industry
best practices
1. Perform the installation on the pump stopped and off.
2. Use connection accessories provided with the OME.
3. Use accessories on the inlet and exhaust lines whose materials and sealing properties are com-
patible with gases being used.
4. Provide in the pumping line, accessories to isolate the pump from the vacuum and exhaust line, to
make the maintenance easier (inlet and exhaust isolation valves, purges,…).
5. Remove the blanking plates blocking the inlet and exhaust ports.
In case of distance installation of the OME from the pump:
●Use the same diameter tube between the pump and the OME.
●Install the OME to a level higher than the pump’s exhaust.
4.1 Fitting direction
A label indicates the fitting direction of the filter on the pump.
►Install the OME on the pump's exhaust respecting the assembly direction.
The side on which the filter element is visible must be mounted on the pump.
The side where the spring is visible must be connected to a chimney or an exhaust duct.

5 Operation
WARNING
Risk of overpressure
At the pump exhaust, the discharge circuit must be such that the resulting overpressure in the oil
case is as low as possible. The maximum overpressure recommended for correct pump operation is
500 hPa. A slight negative pressure in the oil case (100–200 hPa), at the exhaust, will prevent gases
from accumulating and reduce pump corrosion and pollution.
When the OME is installed to a pump exhaust, check periodically that:
►The exhaust valve is not clogged and does not prevent the operation of the OME’s valve.
►The exhaust valve operates to avoid overpressure in the oil case
WARNING
Emission of toxic substances from the exhaust
Danger of poisoning from emitted gases or vapours, which can be detrimental to health and/or can
pollute the environment, depending on the particular application.
►The exhaust valve is not clogged and does not prevent the operation of the OME’s valve.
►The exhaust valve operates to avoid overpressure in the oil case.
Do not reuse an OME that has been stored for a long duration (> 1 year).
Perform maintenance and replace the filtration element before use.
Commissioning
►Turn the pump on.
During operation, oil and vapors are trapped by the filter element until it becomes clogged/saturated. In
this case, the relief valve should open when the internal pressure exceeds atmospheric pressure by
500 hPa.
Decommissioning
1. Stop the pump.
2. Bring the pump back to the atmospheric pressure and let the pump cool down.
3. Make sure the exhaust pipe is not under pressure.
5.1 Filter element saturation
The time taken to reach saturation point depends on the number of pumping cycles, the volume of
pumped gas and the kind of operating fluid used.
The signs of a saturated filter element are :
●Excess of smokes or droplets, or puffs of stream at the OME exhaust
●Rapid or significant drop in the oil level
●Increase of the pump oil case temperature
●Valve noise
When the filter element is saturated, proceed to its replacement (see « Maintenance » chapter)

6 Maintenance
6.1 Maintenance safety instructions
DANGER
Risk to the health in the event of contact with toxic substances
During pump disconnection, operator could be in contact with process residues on the exhaust that
could cause severe injury or death.
►Take the appropriate safety measures to prevent injury. Consult the department manager for in-
structions and safety information.
►Wear gloves, goggles, a respirator or other appropriate safety equipment.
►Ventilate well the premises or work under an extract hood.
►Do not dispose of residues in the usual network and, if necessary, seek a competent agency for
their destruction.
►Do not discard the used filter element in the usual network, seek a competent agency for its de-
struction.
►Set up the blanking plates at the inlet and exhaust of the pump (supplied with the product).

5 Filter element
When the filter element is saturated, proceed to its change as follows:
1. Remove the OME from the pump (possible oil leak), and disassemble it on a workbench.
2. Loosen the 6 nuts by pressing manually on each end of the OME (to avoid sudden release of the
spring), and remove them.
3. Remove the upper nipple and the O-ring.
4. Remove the spring.
5. Remove the valve equipped with the O-ring.
6. Remove the filter element and the flat ring in the bottom of the body.
If when disassembling, the filter element appears very clogged, filled with condensable products or gels,
or is filled with very blackish, strong-smelling oil, pump's oil quality must be checked and probably must

be changed. In this case, drain and rinse the pump, replace the oil before installing an OME equipped
with a new filter element (see Rotary Vane Pump Maintenance Manual).
6.3 Cleaning
Never clean a filtration element!
Always replace the filtration element with a new one.
►Always replace the O-rings with new O-rings.
After using mineral or synthetic oil, clean the parts with a mineral-based solvent, in accordance with the
legislation in force, for example, the type AXAREL, CARECLEAN, PREMACLEAN, NAPHTESOL.
Proceed as follows:
1. Clean when cold or hot (max. 45 °C) by dipping or using lintfree cloth.
2. Vacuum dry in a ventilated heating chamber then.
3. The component must be cleaned a second time with alcohol.
