Air Liquide Demand Flow Regulator DFR2001

The two stage Demand Flow Regulator from Air Liquide is designed for use with instruments that utilize a sample pump to draw the calibration gas. This saves precious calibration gas because 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 instrument and the regulator does the rest. We sell the Air Liquide brand, but list the equivalent part numbers for other brands below.
