Accuracy*: +3% Maximum Flow: 40 LPM Bleed Flow: 2.5 - 4.5 LPM @ 8 LPM FIO2 Range: .21 +0.1 to 1.0 -0.1 Gas Supply Range: 50 psi + 10 psi Sechrist Air / Oxygen gas mixers Model 20457-1 provides for precise mixing of air and oxygen for many clinical applications. Models 20457-1 and 20459-1 are low flow mixers designed for low flow general applications. 20457-1 utilizes a wall mount configuration and 20459-1 provides for pole mounting. Standard Accessories: 0 - 15 LPM flowmeter water trap assembly Optional Accessories: 14 ft. air hose 14 ft. oxygen hose *NOTE: Mixers will maintain the delivered FIO2 within + 1 percentage point of the selected value even with fluctuations in supply pressures. An additional 2% variance may result from the readability of the set point and scale error.
