Xylem-Bell & Gossett 112105 EAS-1 Enhanced Air Separator 1 Inch NPT

The Xylem-Bell & Gossett 112105 EAS-1 Enhanced Air Separator is a highly efficient device designed for removing entrained air bubbles in residential and light commercial hydronic heating and cooling systems. This 1-inch NPT air separator utilizes an advanced combination diffuser and coalescing medium design to effectively remove micro air bubbles from the fluid stream, achieving over 99% air removal efficiency on the first pass.

How It Works:

When system fluid enters the separator, an internal diffuser forces it across the entire inlet portion of the coalescing medium. Air bubbles adhere to the stainless steel wire-like filaments of the coalescing medium, where they coalesce together and rise to the top of the separator. The separated air is then automatically vented to the atmosphere through the included 3/4-inch replaceable automatic air vent, while deaerated water continues through the system.

Key Features:

• Cast iron construction for durability and longevity
• 1-inch NPT connection size with 35 GPM maximum flow rate
• 150 PSI working pressure rating and 250°F maximum temperature
• Compact dimensions: 6-7/16 inches wide x 12-3/16 inches high
• Includes replaceable 3/4-inch large capacity automatic air vent
• Internal stainless steel baffle and brush assembly
• Easy installation in straight or angle pattern pipe configurations
• No minimum pipe run required for installation
• Compatible with both diaphragm and compression tanks

Benefits:

Removing entrained air from hydronic systems increases heat transfer efficiency, saves energy, reduces system noise, and improves overall heating comfort. The EAS-1 differs from standard air scoops by incorporating advanced coalescing technology that captures even the smallest micro bubbles that conventional separators miss.
