The Xylem-Bell & Gossett 113020 is an automatic air vent designed to efficiently remove air from hydronic heating and cooling systems. This compact air elimination device features a 1/8" male NPT thread connection for easy installation in tight spaces and small piping applications.

Key Features:

• Maximum working pressure of 35 PSI for residential and light commercial applications
• Automatic operation continuously vents air without manual intervention
• 1/8" NPTM end connection for standard pipe threading
• Durable brass construction for long-lasting performance
• Float-operated mechanism automatically closes when water is present
• Prevents air pockets that reduce system efficiency and cause noise

This automatic air vent is ideal for use in boilers, radiators, baseboards, radiant heating systems, and closed-loop hydronic systems. By automatically releasing trapped air, the 113020 helps maintain optimal system performance, reduces pump cavitation, and eliminates air-related noise issues.
