? The Heavy Duty Series is an excellent solution for applications where higher air flow is the primary concern. Top level performance and long lasting durability is assured by such features as an extra large bronze filter element, critically close air regulation, mist-type lubricant atomization, and a rugged die cast aluminum body. ? Moist pressurized air enters the inlet port of the desiccant dryer into a bed of silica gel. The silica gel absorbs the water vapor in the air allowing the now dry air to pass through to downstream equipment ? Use of a desiccant dryer requires the placement of a pre-filter and a coalescing filter before the desiccant air dryer and a filter after the dryer ? The desiccant gel can be regenerated for reuse
