How to choose

Use it in low-pressure (max. 3 bar) residential heating and cooling circuits when you want to deal with both air and dirt with one device.
Choose the size by the boiler or heat pump pipe: 3/4", 1" and 1 1/4" female; 1 1/2" and 2" for larger lines.
If the pipe orientation differs, the 1 1/2" and 2" models can be adjusted for horizontal or vertical pipes.
If system pressure can exceed 3 bar, choose separate brass air and dirt separators instead of this series.

How to write it in a quote

Example: "Caleffi 546406 DISCALDIRTMAG air and magnetic dirt separator 1", technopolymer body, 3 bar". As this unit performs both functions, do not list a separate air separator; in circuits that also cool, add the CBN insulation shell as its own line.

FAQ

Does DISCALDIRTMAG replace both an air separator and a dirt separator?

Yes, it combines air separation and magnetic dirt separation in the same body. Its limit, due to the technopolymer body, is a max. working pressure of 3 bar and a max. temperature of 90 °C.

How is the collected dirt removed?

Through the drain cock with hose connection on the body. With a hose the water can go straight to a drain.

Which insulation shell fits which model?

CBN546402 fits 546405 and 546406, CBN546407 fits 546407, CBN546408 fits 546408 and CBN546409 fits 546409.
