VRI-2 Rotary Pump Kit 52 for the #2251-16 Vacuum Desiccator, Including Foreline Trap

This pumping kit is the same as above with an additional foreline trap mounted between rotary pump and the vacuum desiccator.

Includes all metal KF-16 hardware and exhaust filter.
The foreline trap prevents backstreaming from the rotary pump to maintain an oil-free environment (provided the activated alumina for the foreline trap is exchanged at regular intervals).

Best solution with good end vacuum.
Suitable for continuous pumping applications.
