Bell & Gossett 5363-06F-12-003 Rolairtrol Air Separator, 6″ Flange, RL-6F

Description

The Bell & Gossett 5363-06F-12-003 Rolairtrol Air Separator (model RL-6F) is a heavy-duty, high-capacity air elimination solution engineered for large commercial and industrial hydronic heating and cooling systems. Designed to continuously remove entrained air from circulating water systems, the Rolairtrol protects pumps, boilers, and heat exchangers from the damaging effects of air pockets, corrosion, and noise — keeping your system running at peak efficiency.

Constructed with a robust carbon steel shell, this unit is built to withstand the demanding pressures and temperatures found in large-scale hydronic applications. The 6″ flanged connections make installation straightforward in high-flow piping systems, and the less-strainer configuration provides flexibility for installations where a separate strainer is already in place or not required.
