Xylem-Bell & Gossett 112026 Airtrol Tank Fitting for Compression Tanks Plumbing Parts & Accessories - ATF-20 20

The Xylem-Bell & Gossett 112026 ATF-20 Airtrol Tank Fitting is designed to establish and maintain proper liquid levels and system pressurization in hydronic heating systems with compression tanks. This essential component ensures optimal system performance by managing air separation and liquid flow between the compression tank and boiler.

Key Features:

• Cast iron body construction for durability and long service life
• Copper and copper-plated tubes for corrosion resistance
• Brass vent tube fitting for reliable air venting
• 1/2" male NPT tank connection and 3/4" female NPT boiler-side connection
• Designed for compression tanks with diameters up to 22 inches
• Adjustable air tube can be cut to fit smaller diameter tanks
• Maximum working pressure: 175 PSI
• Maximum temperature rating: 250°F

How It Works: The Airtrol tank fitting directs released air to the compression tank during system operation while maintaining proper pressurization. During the off cycle, it permits cooler liquid to flow back to the boiler as the system liquid cools, ensuring efficient operation and preventing system issues.

Important Note: This fitting must be used with an appropriately sized in-line Airtrol or Rolairtrol air separator for proper system function. Ideal for hydronic heating applications including residential and light commercial boiler systems.
