Model 4844 Scavenging "Pop-Off" Valve

Model 4844 Clinical Use The most important component of the scavenging system is the "pop-off" valve. This valve must function effectively as a "pop-off" and as a vehicle to conduct excess anesthetic gas to a ventilation grill or suction source. It attaches directly to any anesthesia machine or to the common mask systems through a scavenging adapter. Our valve design meets these requirements. Features Positive opening and closing Only two moving parts, no springs or diaphragms Variable flow geometry for optimal control Universally adaptable to virtually any anesthesia machine Easy installation on existing machines (estimate 5 minutes with provided wrench) May be used with wall suction (using Scavenger-Vacuum Safety Interface, Model 5300) Specifications Minimum Pressure: 1.5 cm H20 Flow Control: 2.5 turns from positive shutoff to wide open Back Pressure: 6 cm H20 maximum with 50 liter flush (wide open valve) Ports: 3/8" diameter Materials: Chrome plated brass, stainless steel, aluminum, nylon Size: 31/2" long x 11/2" diameter Weight: 1 lb.
