Calefffi 549597A - SEP 4 Hydraulic, Air, Dirt and Magnetic Separator - 1-1/4" Sweat

The Caleffi SEP4 combination separator is a device that incorporates four critical functions for hot or chilled water systems. 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 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 solid impurities in the system without isolating the separator or shutting down the system, the added powerful removable external magnet belt on the lower body removes up to 100% of the ferrous impurities, including magnetite, that can form in a hydronic system. The SEP4 has 2.5 times the ferrous impurities.

Features

• Four functions combined into one device: Minimizes cost for systems requiring primary/ secondary piping. Installing separate air and dirt separators not required.
• Unique geometry and design: Prevents pump conflict by hydraulically decoupling primary and secondary circuits. Preserves design flow in all circuits.
• Internal upper and lower mesh element: Causes micro-bubbles to collect and coalesce for efficient air separation. Deflects and collects both ferrous and non-ferrous debris down to 5 microns size.
• Powerful neodymium rare-earth magnet: Attracts ferrous impurities with 2-1/2 times the removal performance of a standard dirt separator.
• Anti-rotation/anti-vibration pinned float: Creates space between float and air vent wall to prevent float hang-up from debris formation. Enables needle valve to reliably vent out collected air.
• Convenient mounting bracket included: Heavy duty wall-mount bracket simplifies installation and pipe connection alignment.
