DESICCANT REPLACEMENT:

CAUTION: Activated Alumina Desiccant dust is considered
a nuisance dust. Proper precautions should be taken.
Refer to Material Safety Data Sheet.
1.
Remove pressure and power from dryer.
2.
Open drain ports on bottom of tanks.
3.
Catch desiccant in suitable container. Close drain ports
and open top fill ports.
4.
Refill with recommended type, size and quantity of
desiccant. Rap sides of the chamber while filling, so
desiccant will pack tightly. Fill chambers only to within
three inches of the top. Some settling may be required
to fit specified amount in tank. One tank size may be
used for multiple models, do not be concerned if tank is
not full.
5.
Consult Material Safety Data Sheet and all applicable
regulations for disposal of desiccant. Disposal of
desiccant contaminated with oil or other substances
may require different procedures than desiccant
replaced strictly due to aging.
NOTE: Use only AIRTEK Desiccant which is a high
capacity, high quality desiccant designed & sized for
AIRTEK Dryers.

ment; then read to the left for dryer model.

Example: You want to dry 27 SCFM at 80 PSIG – go to the
80 PSIG column and read down to 35 (this is the first
number equal to, or greater than your requirement). Now
read the dryer model number to your left. A model TW40 is
required.
Sizing is approximate only. Consult factory for exact
sizing. Downsizing could cause pressure drop, bed
fluidization, or poor dewpoint performance due to low
contact time.
The above chart assumes 100ºF or less inlet air tempera-
ture. Due to generous bed sizing, most AIRTEK heatless
dryers can be operated at up to 120ºF at 100 PSIG and
rated flow. However, consult factory for any applications
over 100ºF.
