Resideo EA122A1002 Air Vent
The Resideo EA122A1002 Air Vent is a critical component for maintaining hydronic system efficiency by providing continuous, automatic air venting in boilers, radiators, and baseboard units. Designed with a 1/8" NPT connection, this high-capacity float-type vent effectively prevents air binding, which reduces system noise and protects pumps from cavitation. The integrated built-in shutoff valve allows for seamless maintenance or replacement without requiring a full system drain, ensuring minimal downtime on the job site. Constructed with a durable brass body and a high-temperature resistant float, it handles operating pressures up to 150 PSI and temperatures reaching 250°F. This makes the EA122A1002 a standard for residential hydronic heating and small commercial air elimination applications. Its compact profile allows for installation in tight mechanical headers where larger air eliminators cannot fit, providing a reliable solution for automatic air release in closed-loop systems.
Key Benefits- Automatic Air Elimination: Minimizes oxygen levels to prevent internal corrosion and localized boiling.
- Integrated Check Valve: Features a removable vent head and shutoff for servicing under pressure.
- Compact 1/8" NPT Port: Fits standard boiler tapings and radiator air vent ports.
- Heavy-Duty Construction: Built for high-pressure hydronic systems to ensure leak-proof operation.
- System Performance: Improves heat transfer efficiency by removing insulating air pockets from heat exchangers.
Can the Resideo EA122A1002 be used on steam systems?
No, this float-type vent is strictly designed for hydronic heating systems and chilled water applications. It is not rated for steam pressure or temperature.
What is the purpose of the red cap on top of the vent?
The cap serves as a manual shutoff. For automatic venting, the cap must be loosened one or two full turns. Tightening the cap prevents venting or acts as a secondary seal during maintenance.
Where is the best location to install an automatic air vent?
Install the EA122A1002 at the highest points of the system or on air separators where air naturally accumulates and flow velocity is lowest.
