*Air-cooled models; water-cooled models use 1.15 multiplier if cooling
water is below 35°C, 95°F.
SIZING
Determining dryer capacity at actual operating conditions
To determine the maximum inlet flow 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.
