Vacuum Pump Exhaust Kit mounted on an Edwards E2M1.5 Pump The Pump filter Kit for the Edwards Pump includes the Edwards EMF10 Oil Mist Eliminator, Koby Charcoal Trap and all the fittings needed to attach this two filter system on the larger Edwards series of vacuum pumps.  Included is the 3/4 Pump Adaptor which screws into the exhaust port of the vacuum pump.  The oil mist eliminator then attaches to the NW25 flange on this fitting. This kit is to be used with Edwards models E1M5/8, E2M2/3/5/8 and the RV3/5/8 series vacuum pumps.  It can also be used with any other manufacturers pumps that have an NW25 flange type fitting on the exhaust port.

The Koby Charcoal Filters are highly recommended to be placed on the exhaust of vacuum pumps that are normally vented directly into the laboratory.  SIS has undertaken extensive studies on the application and efficiency of the Koby filters when used on vacuum pump exhausts. Vacuum exhaust air which is exhausted  through the Koby filter, has been shown to be cleaner than normal room air.  

Figure # 1 - Effect of Vacuum Pump Exhaust Filtering

The chart above shows the steps in filtering air from a vacuum pump after 1.0 ml of gasoline was injected into the pump.  The top chromatograph shows the low boiling organics as well as high boiling hydrocarbons that are exhausted out of the vacuum pump before any filtering.  The second chromatogram shows the exhaust air after the oil mist eliminator - the oil mist eliminator traps the heavy hydrocarbons from the pump oil and returns them to the pump.  The bottom chromatogram shows the exhaust air after it is filtered through the Koby trap - the exhaust air is cleaner than the normal room air.

For additional information and the results of our studies visit the SIS Application Notes on Vacuum Pump Exhaust Filters:

• # 82 - Vacuum Pump Exhaust Filters, Part I – Two Stage Vacuum Pump Exhaust Filter System

• # 83 Vacuum Pump Exhaust Filters, Part II – Oil Mist Eliminators

• # 84 Vacuum Pump Exhaust Filters, Part III – Charcoal Exhaust Traps

It is normally recommended that the Koby carbon filters  be used in conjunction with an oil mist eliminator. The oil mist eliminator traps and returns the vacuum pump oil to the vacuum pump, preventing this oil from saturating the charcoal filter which will reduce its life. The Koby Air Purifier removes any remaining organic contamination which might otherwise be emitted into the laboratory air.
