The Value VRI Series dual stage rotary vacuum pumps are compact, lightweight, and cost efficient. Ideally suited for a variety of light duty laboratory, research and production vacuum applications. They are equipped with an active solenoid valve to prevent oil-suck-back. Available with pumping speeds of 2, 4 or 8m3/hr with an ultimate pressure of 10-2 mbar.
Applications include laboratory vacuum equipment, air-out systems, vacuum desiccator, backing pump, coating systems, small freeze drying/vacuum food packaging and vacuum molding systems. Excellent specifications, good quality with a low cost. Low weight for easy handling.
# 9609
(mist eliminators)
Filter for removing oil mist from vacuum pump exhaust on the VRI-2 and VRI-4 Compact Rotary Vacuum Pumps (#92092, 92092-230, 92089, 92089-230) and to be used with #92465-16 adapter. Can be used with other rotary vane pump with NW/KF 16 output flange. Creates a cleaner work environment for operators and surrounding equipment. Connection: 1/4" male NPT thread.
To be used with VRI-8 Compact Rotary Vacuum Pump (#92098 and 92098-230) with adapter #92466-25. Permits discharge into clean work areas. Return collected oil to sump or discard. Rugged construction, simple installation. For non-hazardous, non-corrosive applications. Connection: 1/2" male NPT thread. Color of filter material may vary from white to yellow.
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.
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:
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).
Highly recommended to prevent oil backstreaming from rotary vane pumps. Keeps your vacuum system clean in applications where pumps are running constantly such as mass spectrometer, electron microscope, and vacuum drying systems. Protect vacuum gauges when mounted in front of the gauges. Includes a 150ml Activated Alumina charge (renew the charge every 3 months with #92090-50).
Available with both NW/KF 16 and NW/KF 25 flanges and, with appropriate flange selection, are compatible with the RVP, VRP, Pfeiffer DUO 3.0, VRI-4, and VRI-8 pumps available. Compatible with smaller VRI-2 #92092/92092-230 pump with addition of Connection Kit #92090-VRI. See Technical Notes for #92090-VRI (483KB PDF).
Anti-vibration pads to be placed under rotary-vane backing pumps to dampen vibration. Soft closed-cell foam mat made of a blend of Buna-N, neoprene, and vinyl. Oil resistant and flame retardant. Available in two sizes. Smaller size #91020-27 is suitable for the VRI-2 and VRI-4 Pumps and larger #91020-29 size for the VRI-8, RVP, and VRP-series Pumps.
