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).
