• Four functions combined into one device - minimizes components and labor costs for system requiring primary/secondary piping, separate air and dirt separators not required Internal upper and lower mesh element Powerful neodymium rare earth magnet Unique geometry and design Anti-rotation/anti-vibration pinned float HDPE internal coalescing element, removable for cleaning Pre-formed insulation 32 to 230 deg F working temp range without insulation 100% ferrous impurities separation efficiency 100% to micro-bubble level air separation efficiency

The Caleffi SEP4™ combination air, hydraulic, dirt and magnetic separator is a device that, incorporates high-performance air and magnetic and non-magnetic dirt removal functionality into the hydraulic separation function which makes the primary and secondary circuits connected to it hydraulically independent and can be used on hot or chilled water systems. The SEP4™ features an HDPE internal element that combines to continuously and automatically eliminate air micro-bubbles with the simultaneous removal of dirt particles as tiny as 5 micron. 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-performance 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 sand and rust impurities, the added magnetic ring provides effective capture of ferrous particles.
