Selecting the correct Inlet Filter to remove whatever particulate matter or fluids that may be entrained in the process gas flow allows Agilent's High Capacity Rotary Vane pumps to maintain optimal pumping speed while protecting against premature wear to the pumping mechanism. Agilent offers a selection of Inlet Filters and Traps to remove most types of contamination that could cause loss of pumping speed, and shortening of pump life.
