  • Summary
  • Applications

    Dirt and air removal from hydronic and HVAC systems

  • Description

    The Armstrong dirt & air separators (DAS) are designed to eliminate trapped air and suspended dirt particles associated with the start-up and maintenance of hydronic and HVAC systems.

  • Materials

    Carbon steel (shell), stainless steel (coalescing medium), styrene butadiene rubber (gasket)

Low installed cost

  • Space saving design removes dirt and air at the same time within a single unit
  • DAS eliminates the need for bypass/isolation valves, filters and other components

Improved system efficiency and operating economy

  • DAS eliminates the need for bypass/isolation valves, filters and other components that tend to aggravate system friction
  • Design for minimal pressure drop and no fluctuations
  • Less corrosion, pump cavitation and wear of system components for extended service intervals and overall system life
  • Service-friendly design allows flushing of dirt particles and air-vent maintenance while system is in operation
