It is a non-discharge low-pressure precision pressure regulator designed for applications requiring high performance and precise process control at low pressures as low as 2 inches of water column. With control sensitivity of less than 0.05" water column, low consumption and high flow rate, the Fairchild 4100A Pneumatic low pressure regulator provides accurate and reliable accuracy, maintaining the required set point regardless of supply pressure changes or conditions. The Fairchild Model 4100A high Precision Pressure regulator will handle large supply pressures of 150 psi, 10 BAR, and provide four (4) output pressure ranges from 0-0.7 psi, 0-0.048 BAR, 0-4.8 kPa to 0-5 psi, 0-0.35 bar, 0-35 kilopascal. The Model 4100A has a flow rate of 30 SCFM, 51 m3 / h
