Two-Stage Vacuum Pump Exhaust Filter Assembled Two-Stage Vacuum Pump Exhaust Filter Kit

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).
