Exhaust Filter for Vacuum Rotary Vane Pumps, 1/2" NPT Oil mist eliminators 92060 and 92061 92466-25 Exhaust Filter Adapter,NW/KF 25 to 1/2" NPT Permits discharge into clean work areas. Return collected oil to sump or discard. Rugged construction, simple installation. For non-hazardous, non-corrosive applications. Fits on VRP 100-3.5, VRP-8, Edwards RV5, or similar. Connection: 1/2" male NPT thread. Color of filter material may vary from white to yellow. Compact Oil Mist Eliminator 92066 92066-10 Compact Oil Mist Eliminator with KF25 connection and 1/8" drain plug. Max flow rate 10 CFM (5 ltr/sec or 16m³/hr). Baked enamel steel housing, ø89 x 127mm H (ø3.5 x 5" H). Use replacement filter #92066-10. Suitable for RVP Series, VRP-8, VRP-16, and VRI-8.The VRP-4 and Pfeiffer DUO 3.0 have a KF16 exhaust connection, so the mist eliminator can be used with these pumps if a NW/KF 25 to 16 conical reducer #92450-2516 and appropriate NW/KF 25 clamp/centering ring #92210-25 and #92220-25 are purchased. For use with the smaller VRI-2 and VRI-4 Pumps, the Connection Kit #92068-VRI is required. See Technical Notes for #92068-VRI (549KB PDF). Two-Stage Vacuum Pump Exhaust Filter For rotary vacuum pumps it is recommended that they should be vented outside the room or to a laboratory exhaust hood to prevent indoor air contamination. This two-stage vacuum pump exhaust filter kit enables venting rotary vacuum pumps in rooms where an outside line is either not practical or possible. The two stage filters contains a replaceable oil mist eliminator element to trap vacuum oil and a replaceable activated charcoal element for the lighter hydrocarbon fractions. Features: Provides a safe lab environment Purifies vacuum exhaust gases Separate replaceable elements for oil mist and lighter fractions Only 6-1/4" tall with standard NW/KF 25 connection Low cost solution It is recommended that both filters are replaced on a regular basis. For application such as electron microscopes and mass spectrometers, the oil mist filters (#92066-10) need to be replaced every 4-6 months and the final activated charcoal filter (#92068-20) once a month. Rated for vacuum pumps up to 10 CFM (5 ltr/sec or 16m³/hr). Suitable for RVP Series, VRP-8, VRP-16, and VRI-8.The VRP-4 and Pfeiffer DUO 3.0 have a KF16 exhaust connection, the Two-Stage Vacuum Pump Exhaust Filter can be used with these pumps if a NW/KF 25 to 16 conical reducer (#92450-2516) and appropriate NW/KF 25 clamp/centering ring (#92210-25/92220-25) are purchased. For use with the smaller VRI-2 and VRI-4 Pumps, the Connection Kit #92068-VRI is needed. See Technical Notes for #92068-VRI (549KB PDF).
