Function

The Caleffi SEP4™ combination separator is a device that

incorporates four critical functions for hot or chilled water sys-

tems. It combines high performance air and dirt (magnetic and

non-magnetic) removal into the hydraulic separation function

which makes the primary and secondary circuits connected to

it hydraulically independent. The SEP4™ features an internal

coalescing element that continuously and automatically eliminates

air micro-bubbles with the simultaneous removal of dirt particles

as tiny as 5 microns. The air discharge capacity is very high, with

the capability of automatically removing all the air present in the

system down to the micro-bubble level. The 4-in-1 high perfor-

mance functionality of the SEP4™ saves system installation and

maintenance costs as there is no need to include separate air

and dirt separators. In addition to removing solid impurities in the

system without isolating the separator or shutting down the sys-

tem, the added powerful removable external magnet belt (union)

or probe(s) (ﬂanged) in the lower body removes up to 100% of the

ferrous impurities, including magnetite, that can form in a hydronic

system. The SEP4™ has 2½ times the ferrous impurities removal

performance of standard air and dirt separators.

These items are designed for use in closed hydronic systems. Do not use in plumbing applications. These

items do not meet the low-lead plumbing standards of U.S. and Canada.
