ATIONAL LINETM ATIONAL LINETM TM NATIONAL LINE FILTER SYSTEMS MODEL SELECTION The National Filter Systems are available in three (3) horizontal designs. They come in 34”, 42” and 60” diameter tanks in various lengths. They are available in 50 or 100 P.S.I.G. operating pressures with top or end mount piping configurations (Filter Model 34-075, 60-200, and 60-250 not available in top mount piping). This provides a wide range of filter bed surface areas from 7.5 up to 80 sq. ft. in 355 different models. NATIONAL FILTERS TM All National Line Filter Systems can be used with multiple types of granular media or one (1) single grade of # 20 or # 30silica sand. The NFS-60 filtration system has a 27” usable filter media bed depth and can be used in multi-media configurations. NSF International, for single tank flow capacities, certifies all National Line Filter Systems to ANSI / NSF Standard 50 for both pool and spa applications from 37.5 to 1,600 U.S. GPM.

NOTE: National Line™ NFS-Series Filters are certified by NSF International to ANSI / NSF Standard 50 for both pool and spa applications at filtration rates of 5 to 20 U.S. GPM / sq. ft. All NFS-Series Filters are certified by NSF International for use with # 20 grade silica sand, Zeoclere-30 zeolite or Zeobrite® zeolite in fresh water/ salt water applications. Filter media and pumping equipment are NOT included with the filter tanks. ENGINEERING NOTES: All National Line™ NFS Filter Systems will have varying head loss that is dependent upon filter media and operational flow rates. Filters should be backwashed when 15 to 17 PSIG differential is indicated on the influent and effluent pressure gauges. When sizing the main circulation pump, calculate maximum head loss at 15 to 20 PSIG through the filter and face piping. EMATO CORP. EMATO CORP. 1605 McEwen Dr., Whitby, Ont., Can.
