Resideo by Honeywell PV125 Air Eliminator 1-1/4 Inch NPT

The Resideo by Honeywell PV125 Air Eliminator is designed to efficiently remove air from hydronic heating and cooling systems. This high-performance air separator features a 1-1/4 inch NPT threaded connection, making it suitable for medium-sized residential and light commercial applications.

Key Features:

• 1-1/4 inch NPT threaded connections for easy installation
• Efficiently removes microbubbles and entrained air from hydronic systems
• Reduces system noise caused by trapped air
• Improves heat transfer efficiency and system performance
• Durable brass construction for long-lasting reliability
• Compact design saves installation space
• Manual vent valve for air purging during system startup

Air eliminators are essential components in hydronic systems, preventing circulation problems, corrosion, and pump cavitation caused by air accumulation. The PV125 uses a combination of velocity reduction and directional change to separate air from water, allowing it to be vented from the system automatically.
