Resideo by Honeywell EA79A1004 3/4" x 1/2" NPT Industrial Air Vent 150 PSI

The Resideo by Honeywell EA79A1004 is a heavy-duty industrial air vent designed for automatic air elimination in hydronic heating systems, hot water systems, and industrial process applications. This automatic air vent features a 3/4-inch male inlet connection and 1/2-inch NPT female outlet, providing versatile installation options for professional HVAC and industrial systems.

Key Features:

• Maximum working pressure of 150 PSI for demanding industrial applications
• Temperature rating up to 250°F for high-temperature systems
• Automatic air venting eliminates trapped air to improve system efficiency
• Durable brass construction for long-lasting performance
• 3/4-inch male x 1/2-inch NPT female connections for flexible piping configurations
• Float-operated mechanism provides reliable, maintenance-free operation

This industrial-grade air vent helps prevent air pockets that can cause noise, corrosion, and reduced heat transfer efficiency in closed-loop systems. The automatic float design continuously removes air without manual intervention, making it ideal for commercial boilers, chilled water systems, and process heating applications.
