It is a compact, battery operated, motorized sample drawing pump which attaches to the GX-3R to change it from diffusion operation to sample drawing operation. Together the model RP-3R pump assembly and the GX-R3 gas monitor make a complete solution for confined space entry.

All pumps include a 4” tapered red nozzle for sampling and attach onto the GX-3R. All RP-3R pumps include built-in dust and hydrophobic filters, and one “AA” alkaline battery.
