System Operations The Acme Model CF-1200 AR gas blender utilizes throttling orifices and a needle valve to pneumatically control flow into the tank. As the gas in the tank is depleted, the pressure drops to a pre-determined level where constant flow blending automatically begins. When the higher pressure level is achieved, the unit automatically shuts off until the cycle is repeated.||Based on system demands, the CF-1200 AR blender can be custom sized and built to deliver a wide range of flow rates, up to 4000 SCFH. This blender is equipped with inlet filters and pressure regulators, and can also be built with an automatic shutdown feature.||This blender can be supplied with dual orifices for a fixed ratio (CF-1200FR).||If large laboratory requirements for gas mixtures are anticipated, users should consider the CF-1200 AR, as significant cost savings may be realized.
