NFS Series (600-80,000 CFM)
Flanged Moisture Separator
The NFS series separators are an ideal solution for medium to large flow applications. Our range of Flanged Water Separators include connections ranging from 2″npt to 12″ flg. Stainless steel internal parts for maintenance-free operation and a side mounted drain port provides permanent drainage to an electronic drain or for a drain balance line.
Next’s series flange separators are designed to eliminate 99% of all entrained liquids and particles that are 10 microns and larger in size. The NFS – Series are fabricated from carbon or stainless steel and are manufactured in accordance with ASME CODE Section VIII, Division The NFS-CT series separators are fabricated from cast iron which meets ASTM-A-278 Class 35 standards are designed to meet ASME Code, Section VIII for unfired pressure vessels. The unique centrifugal action removes contaminants at low pressure drop from maximum energy savings.
By installing the Fabricated Flanged Water Separator, you will reduce the risk of contamination to production equipment, product spoilage, and costly shutdowns caused by damage from high levels of moisture and condensate in the system.
Note: While highly efficient, condensate separators will not remove the oil from the air stream, additional coalescing and particulate filters down stream may be required to remove fine traces of oil, water and particles.

Overview
Principle of Operation
Gas, laden with moisture enters the inlet of the separator where a deflector plate directs the flow in a downward centrifugal motion. The entrained moisture is then separated out of the flow by a reduction in velocity. The separated liquid is sent to the outer walls of the separator and falls below the re-entrainment breaker plate where it is prevented from re-entering the flow stream. A dry, clean flow then results, exiting upward through the outlet separator.
Bulk water separation is a critical early step in the compressed air treatment process. Water separators remove large diameter water droplets from the air stream, enhancing the performance and durability of downstream treatment equipment such as coalescing filters and air dryers. Water separators are typically installed immediately downstream of coolers and wet receiver tanks.
