Resideo EA79A1004 Air Vent
The Resideo EA79A1004 Air Vent is a professional-grade solution for purging air from high-pressure mains and equipment in both hot and cold closed-loop water systems. Designed with a heavy-duty brass shell construction, this industrial-grade automatic vent ensures quiet and efficient system operation by eliminating air pockets that cause airlock and noise. This 3/4" AutoAirVent W/Shutoff includes a dual-connection configuration with a 3/4-inch male NPT pipe thread and a 1/2-inch female NPT thread, providing versatile installation options for hydronic heating systems.
Engineered for high-performance environments, the EA79A1004 air vent features a built-in shutoff valve, allowing for immediate servicing or replacement without requiring a full system shutdown. The internal components are manufactured from chemical-resistant and corrosion-resistant materials, making it fully compatible with systems containing propylene glycol, mineral oils, or petroleum-based fluids. This unit also incorporates a built-in vacuum breaker and a safety drain connection with a leakage guard to protect the mechanical integrity of the loop under variable pressure conditions up to 150 psi.
- Internal Shutoff Valve: Enables seamless maintenance and component replacement without depressurizing the entire loop.
- High Temperature & Pressure Rating: Rated for a maximum operating temperature of 250°F and safe operating pressures up to 150 psi.
- Chemical Compatibility: Corrosion-resistant internals support use in hydronic systems with common glycol and oil additives.
- Vacuum Breaker Inclusion: Integrated safety feature prevents vacuum-related issues and ensures consistent automatic air venting.
- Flexible Connectivity: Features a dual-threaded 3/4" MNPT and 1/2" FNPT design to simplify retrofitting across diverse piping layouts.
Common Questions
Can the EA79A1004 be used in systems with glycol?
Yes, the internal float and valve assembly are constructed from engineered thermoplastics and synthetic rubber specifically designed to withstand propylene glycol and other common chemical additives in hydronic systems.
How do I service the vent without draining the system?
The integrated shutoff valve automatically isolates the vent assembly when you unscrew the body, allowing for cleaning or repair while the system remains under pressure.
What is the purpose of the safety drain connection?
The safety drain port on the vent cap provides a specific attachment point to pipe away any potential discharge, preventing moisture damage in sensitive mechanical spaces.
