As all regenerative desiccant dryers are designed to remove only water vapor, any possibility of liquid
water carryover to the desiccant dryer must be avoided. Coalescing pre-filtration will eliminate the
carryover of droplets, aerosols, and compressor lubricant liquids. Proper filtration will not only enhance
the dew point suppression capability of the dryer, but will also add years of life to the desiccant by
preventing fouling of the desiccant caused by compressor lubricants.
Coalescing pre-filtration of ISO Class-1(8573) with a max. oil carryover 0.008 PPM w/w is
required under the equipment warranty.
CONDENSATE
A typical compressed air system has multiple points that require condensate removal: the compressor,
the aftercooler, receiver tank and coalescing pre-filter. It is urgent that each of these drains is not
piped to a common header that will allow condensate to be pumped from a high-pressure location to a
low-pressure location.
common header system. This concept seems reliable in theory; however a drain system failure will be
imminent. The health of your compressed air dehydration system is contingent on a clean and properly
designed condensate removal system.
AFTER-FILTRATION
All regenerative desiccant dryers gradually produce hard and abrasive desiccant fines. These
contaminants should be removed with a high quality particulate after-filter capable of removing 1.0 µm
particles.
Particulate filters located downstream of Regenerative Air Dryers do not have automated drain systems.
The material collected should be held in the bottom of the housing; no draining is necessary. Simply
clean out the sump area as an element is replaced.
ECOMMENDED SYSTEM DESIGN
BLOCK & BYPASS
All compressed air dryer systems should have a bypass system to facilitate servicing the dryer and
filters without interrupting compressed air flow. Valves should be bubble-tight to prevent water vapor
migration around the system from the regions of high relative humidity to low relative humidity. The
bypass system should be capable of bypassing each filter or the dryer and any combination thereof.
Operation in this condition for extended periods of time is not recommended because of possible
system contamination (i.e. desiccant dust downstream, moisture downstream, or oil in the desiccant).
Some facilities have tried to install check valves to prevent backflow in a
