13. Save Energy with HF Series Filters Filter housing provides large flow paths which minimizes pressure losses The seven element grades allow for system customization HF SERIES FILTERS

14. Elements Designed to Extend Life and Reduce Pressure Losses Large 45% open area stainless steel cores provide even air flow through media at minimal pressure losses Filter media with over 96% void volume, lowers pressure losses while matrix blended media increases capture efficiency Thick filter bed extends useable life without adding pressure losses HF SERIES FILTERS

15. Reliable Differential Pressure Gauges & Monitor Save Energy Three available methods of Differential pressure indication Electronic intelligence of the Filter Monitor Face Gauge Slide Indicator Changing the filter elements at the proper time saves energy and protects the compressed air system HF SERIES FILTERS

16. Saving Energy by Replacing Filter Elements Reduce energy losses by knowing when its cost effective to replace the filter elements Differential pressure gauges determine the end of an element’s life. Further contaminant loading beyond this point greatly increases system pressure losses Saves money and greatly minimize pressure losses in systems by replacing the elements at the end of their efficient life Filter monitor calculates the point of maximum element efficiency. Loading beyond this point increases pressure to the end of the element’s life. HF SERIES FILTERS
