Air Liquide Demand Flow Regulator

The two stage DFR2000 Series regulator from Air Liquide is designed for use with instruments that ultilize a sample pump to draw the calibration gas. This saves precious cal gas, in that gas flows only as pulled by the pump. The regulator provides the exact amount of gas the instrument pump requires. This simple-to-use regulator makes calibration quick and easy, just thread on to the cylinder and slide the tubing on to the barbed fitting. With no valves to turn, just start the insrument and the regulator does the rest. We sell the Air Liquide brand, but list the equivalent part numbers for other brands below.
