SIZING
Determining dryer capacity at actual operating conditions
Todeterminethemaximuminletowcapacityofadryer
at various operating conditions, multiply the rated capacity
from Table 1 by the multipliers shown in Table 2.
Example:Howmanyscfmcananair-cooledmodelTF171E
handle when compressed air to be dried is at 200 psig and
100°F; ambient air temperature is 80°F?
Answer:600x1.22x1.12 = 820 scfm.

3.0 MAINTENANCE
3.1 Condenser coil – Clean off accumulated dust and
dirt monthly.
3.2 Moisture separator – Replace filter element
when pressure drop across dryer is excessive or
annually.
3.3 Check separator daily to be sure automatic drain
is discharging.
3.4 Blow down separator weekly by pushing test
button on control panel.
3.5 Rebuild drain mechanism annually.
To facilitate service, maintenance kits are available.
