The heat exchanger is located at right side of
the unit under the side panel. Under normal
conditions the heat exchanger should not need
to be replaced.
Replace it if the dehydrator has been dropped
or otherwise damaged such that the heat
exchanger is leaking air.
Verify that you have the latest filter bowl
assembly as shown below. If you do not have
this filter bowl assembly you will need to replace
this assembly with item 5 from the Three-Year
Recommended Dehydrator Spare Parts list. If
you have the latest filter bowl assembly continue
to section 7.10 and 7.11.
7.10 Replace Water Filter Element - 6000 hour
When ambient room air is compressed in the
dehydrator compressor, liquid water is formed.
This liquid water must be removed in order to
allow the membrane dryer to function at its peak
efficiency. As the air exits the compressor, it is
cooled in the heat exchanger and then enters
into the water filter. The air swirls around the
inside of the filter bowl, separating the liquid
water out on the sides of the filter bowl. A 5
micron filter is also provided in the water filter
to prevent water droplets from exiting the filter.
This 5 micron filter also filters out any dust
particles or other contaminants which would
lessen the efficiency of the membrane dryer.
To replace the filter element, twist and remove
the filter bowl from the cast housing. Unscrew
the filter element from the cast filter housing and
replace with a new filter. Do not attempt to clean
the filter element. If it is necessary to clean the
filter bowl, use a mild soap and water solution
and rinse with water. Do not use solvents.
Reassemble the unit by reversing the above
procedure. Check for leaks by turning the unit
on and applying a dilute detergent and water
solution at the bowl/housing seal and at the hose
fittings which were reconnected. If no leaks are
found, the unit is ready to return to service. If
leaks are located, repair the leak and recheck
for additional leaks. Leaking fittings must be
repaired or the unit will not function properly and
can result in damage to the transmission line
system.
Replace Coalescing Filter Element
The coalescing filter is located downstream
from the water filter. Its function is to remove
any “water fog” which may still be present in the
air leaving the water filter. The coalescing filter
traps any fine liquid water particles, including
aerosols and causes them to coalesce into
larger droplets. These droplets fall to the bottom
of the bowl and are blown out and carried to the
compressor head, where they evaporate.

the filter bowl from the cast housing. Unscrew
the filter element from the cast filter housing and

the filter element. If it is necessary to clean the
