The Caleffi NA546300AM is a DISCALDIRTMAG air & magnetic dirt separator with 12" ANSI Flange connections. It is installed in the circuit to remove entrained air and dirt before it reaches pumps, control valves and heat exchangers.
Best where space allows only one device but both air and ferrous dirt must be removed.

Key Features
Coalescing Air Separation
An internal medium coalesces microbubbles out of the flow stream and routes them to an automatic vent, removing air that a point vent alone will not capture.
Low-Velocity Dirt Collection
An enlarged chamber drops fluid velocity so heavier particulate settles into a collection zone that can be flushed without shutting the system down.
Magnetic Ferrous Capture
A Neodymium rare-earth assembly captures ferrous debris that a non-magnetic separator passes straight through, protecting pumps and heat exchangers.
Construction
Body material: Steel.
