Hydro separator
548 series

Replaces 01076/16 NA
Function
The Caleffi 548 and NA548 series hydraulic separator creates a zone with
a low pressure loss, which enables connected primary and secondary
circuits to be hydraulically independent of each other; the ow in one
circuit does not create or interupt ow in another. Hydraulically
decoupling primary and seconary circuits eliminates pump conflict.
This device includes an automatic high-capacity air vent with service valve
to discharge accumulated air within the circuits.
