will remove heavy liquid water and solid particulates down to 40
micron size. The second stage (1037) will remove oil and water
aerosols and particles down to .03 micron in size.
NOTE: Used desiccant material can be regenerated by spreading
desiccant material in a thin layer in a shallow container, heating in a
circulating oven at 275°F until complete color transformation takes
place, approximately three hours. Caution - do not pre-heat oven or
exceed 350°F.
MAINTENANCE: Care must be taken to change the dryer's desiccant
material or regenerate it whenever it appears completely pink in color
(check sight glass). Following are the steps to be taken when
recharging dryer: 1) shut off air supply and bleed system. 2) Unscrew
ring nut, remove bowl assembly. 3) Remove used desiccant material.
4) Check and clean if necessary, the exhaust tube of dust particles by
removing acorn nut, gasket seal and exhaust filter. When cleaning is
complete reassemble exhaust filter, gasket seal and nut. 5) Remove
sight glass retainer and sight glass. Remove used desiccant material
from sight glass and bowl. Refill bowl and sight glass with new or
recharged desiccant. NOTE: Whenever filling leave 1/2" gap from top
