Armstrong's line of Dirt & Air Separators (DAS) are designed to eliminate entrained air and suspended dirt particles associated with the start-up and maintenance of hydronic systems. The units incorporate a robust stainless steel coalescing medium which directs dirt particles of all sizes to the collection chamber at the bottom, and allows the air to be released through an air vent at the top.
For applications with high pipe velocity and flow, Armstrong's DASH (High Velocity) unit allows increased flow capacity for the same connection size.
The DAS Series is available with either a welded or removable head, both of which conform to ASME Section VIII, Div. 1. The welded head design is also available, for a price reduction, as a non-ASME rated unit. All models are available with NPT connections up to 4".
