The 4900 Series scrubber system separator removes air and dirt in hydronic systems. It is designed and constructed to ASME code standards, and it employs European-proven PALL ring technology that will remove microbubbles as small as 18 x 10-6m from the system along with dissolved air and solid particles. Two models are offered in the series: 4900-A models clean the system of free air and microbubbles, and 4900-AD models remove both air and dirt from hydronic heating systems or chilled water systems.
