Bell & Gossett 112464 2″ NPT EAS Jr. Air Eliminator

Bell & Gossett has introduced the EASB-JR, a micro-bubble air separator that makes both residential and commercial hydronic heating systems more efficient, operate quieter, and last longer.
Featuring a brass body and stainless steel internal components, the EASB-JR Air Separator is designed to automatically remove entrained air bubbles in hydronic systems. As fluid enters the air separator, the velocity is decreased creating a low-pressure area. The small bubbles are released from fluid and then collect on the coalescing medium. As the bubbles coalesce, they rise to the top of the air separator where they are released to atmosphere through the built-in automatic air vent.
