Product description
The oil mist eliminator is mounted on the exhaust port of rotary vane pumps. It filters oil mist particles out of the supported stream of gas, thereby reducing the operating fluid mist discharge.
The filter elements have been installed in a corrosion-resistant aluminium casing and consist of a glass polyester fleece cylindrical filter. A built-in pressure relief valve opens if the filter element becomes too dirty so that the maximum operating pressure never goes above 1500 hPa (absolute). The collected operating fluid can be observed through a sight-glass and discharged with a drain screw.
To return the filtered operating fluid from the OME into the pump without interrupting the pump operation, an operating fluid return (optional) can be used.

If the operating fluid accumulated in the OME reaches a specified level, the operating fluid is channeled via differential pressure back into the rotary vane pump. Condensate concentrates underneath the oilpan and has to be drained when necessary so as not to impair the operation of the pump
The use of the operating fluid return increases the operational safety of the pump and reduces the maintenance requirements.

Installation

5 Installation

5.1 Assembly

To install the OME in a vacuum system, ISO small flanges or ISO clamp flanges are pro­vided on the input side and output side. The flanges are provided with protective caps when delivered to protect the sealing surfaces.
If gases are pumped that may not enter the atmosphere, an exhaust line must be con­nected to the exhaust flange.
If large amounts of vapor arise during operation, it is recommendable to install a conden­sate separator between the rotary vane pump and OME so that condensate is removed in the KAS, and only oil mist enters the OME.
The OME can also be mounted beside the pump. When doing this, the position of the installation must be maintained and the connecting and return drainage pipes going down towards the pump be moved.
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 instruc-
tions.
NOTICE
Vacuum component
Dirt and damage impair the function of the vacuum component.
When handling vacuum components, ensure that they are kept clean and are protect-
ed against damage.
Ensure that the connection flange is clean, dry and free of grease.
Turn off the vacuum pump, vent to atmospheric pressure and allow to cool.Remove the protective caps from the connection flanges.Place the OME on the exhaust side of the rotary vane pump with the sight glass facing
downward onto the flange, and fasten it with the clamping ring (accessory) or bracket screws (accessory), if clamp flanges are used; observe centering ring (accessory).
If a centring-ring with an outlet nozzle has been fitted at the side of the pump, re-
place this with a standard version centring-ring.
If an exhaust valve has been fitted in at the side of the pump, this must be removed.
Lay exhaust line from the OME sloping downward so that no condensate can flow
back. – If an air trap is created in the system, then a device for draining condensation water
must be provided at the lowest point.
OME 16 ATEX If an ATEX version has been installed a stainless-steel clamping ring must definitely
be used. This clamping ring comes included with the pump and ensures that the OME is properly grounded.

6Operation

Watch out for excess pressure in the exhaust line.
There is a risk of damage to the seals, and a risk of rupture or overloading of the pump.
Ensure that there is no excess pressure at the OME exit point.Open the inlet valves either before or at same time as starting the pump.
Damage to the pump due to condensate in the operating fluid!
Returned condensate generated by vapors or by temperature differences between the oil mist eliminator and pump impairs the quality of the operating fluid and negatively im­pacts the pump's final vacuum.
Drain operating fluid built up with condensate in a time manner.
Risk of the filter elements becoming blocked with resin!
When pumping gases and vapors with a tendency towards polymerization, the OME fil­ter elements can become resinified.
Observe the corresponding safety devices such as the saturation indicator or pres-
Operation

NOTICE
NOTICE
sure relief valve.
NOTICE
Make sure that the return for the operating fluid works.
Operating fluid is only sucked in and returned from an operating pressure of < 100 hPa and starting from a minimum quantity of operating fluid in the OME.
Long evacuation phases with a high intake pressure should always be followed by
operating phases with a lower operating pressure.
Please note that the smallest oil particles can only be separated to a limited ex­tent.
The degree of separation of the filter elements depends upon the gas flow rate and the distribution of particles in the gas flow.
An increased leakage of oil mist at the exhaust flange of the OME as well as a func-
tional decline in the operating fluid return serve as an indicator of the saturation level fo the the filter element.

WARNING
WARNING
Operating fluid return line
Check the operating fluid level in the sight glass.Turn off the vacuum pump, vent to atmospheric pressure and allow to cool.Ensure that the exhaust line is depressurized.Unscrew operating fluid drain screw 33.Drain off operating fluid.Screw in operating fluid drain screw 33; pay attention to O-ring.Separate the operating fluid from the condensate.
– If the drained operating fluid is free of contamination, it can be reused.
Dispose of condensate according to the respectively valid legal requirements.
Due to the automatic operating fluid return, it is not necessary to drain the operating fluid manually.
However, depending on the process, filtered condensate in the oil sump should occa­sionally be drained in the OME, since it could enter the operating fluid return to the pump.
NOTICE
Make sure that the return for the operating fluid is working properly.
The operating fluid can only be sucked out and returned when there is a minimum about of operating fluid in the oil mist eliminator.
If necessary, top up with operating fluid in order to ensure the return of operating fluid
