Armstrong International C3510-2 Vent

The Armstrong International C3510-2 Vent, also recognized as the 1AV-3/4-146, is a high-performance Series 1AV cast iron free floating lever air and gas vent designed for reliable industrial automation. This robust HVACR air vent features a 3/4 inch NPT inlet and a 1/4 inch NPT outlet, specifically engineered to handle maximum operating pressures up to 146 PSI. Utilizing a 1/8 inch orifice, the C3510-2 effectively removes air and non-condensable gases from pressurized liquid systems, protecting your infrastructure from air binding and corrosion. Constructed with a heavy-duty cast iron body and durable stainless steel internal components, this floating lever air vent ensures long-term service in demanding environments. Whether integrated into hydronic heating systems or liquid transport lines, the Armstrong C3510-2 provides a mechanical solution for maintaining system efficiency and preventing flow disruptions caused by trapped air pockets.
