Agilent offers both inlet traps and inlet filters for use with the Agilent line of rotary vane pumps. When operating under molecular flow conditions, an Inlet trap with a stainless-steel wool element protects the vacuum space from oil contamination due to oil back-streaming from the pump inlet.

For applications where the gas stream may carry particulate or other foreign material into the pump, an inlet filter provides protection against potentially severe damage to the pumping mechanism by removing any particulate or debris from the gas stream before it can enter the pump.
