Bell & Gossett 5363-02N-12-002 Rolairtrol Air Separator, 2″ NPT, RL-2N

Description

The Bell & Gossett 5363-02N-12-002 Rolairtrol Air Separator is a high-performance, tangential-flow air elimination device engineered for hydronic heating and cooling systems. Designed to continuously remove entrained air from circulating water, the Rolairtrol protects system components, maximizes heat transfer efficiency, and reduces noise caused by air pockets in the piping loop.

Using a centrifugal separation principle, water enters the separator tangentially, creating a swirling action that drives air bubbles to the low-velocity center of the vessel where they rise and are vented — all without moving parts for long-term, maintenance-free operation. The RL-2N model ships without a strainer, making it ideal for installations where a separate strainer is already in place or not required.
