Armstrong Air & Dirt Separators
- 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 (MOC)-Carbon steel (shell), stainless steel (coalescing medium), styrene butadiene rubber (gasket)
Benefits & Features
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

POT-BASKET TYPE STRAINER (ANSI 150#, 300#)
Applications:
Strainer can be used in liquid as well as gas line, Regulator and valve protection, steam traps protections, flow meter and pump protections, heat exchanger and refrigeration set protection, Suitable for Hazardous environments.
Y-Strainers and pot basket type strainers is a device for mechanically removing unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. Where the amount of material to be removed from the flow is relatively small, resulting in long intervals between screen cleanings, the strainer screen is manually cleaned by shutting down the line and removing the strainer cap.
