NOTE : To determine inlet flow at pressures other than 100 psig (7 kgf/cm²) multiply inlet flow at 100 psig from Table 1 by the multiplier that corresponds to your operating pressure from Table 2.

Operating Parameters

Maximum Working Pressure 150 psig standard.Higher pressures are available

Minimum Operating Pressure for 150 psig models are 60 psig
Minimum Operating Pressure for 250 psig models are 120 psig
Maximum inlet or ambient air temperature 120° F (49° C)
Pressure drop at rated flow is less than 5 psi
Standard voltages: Controllers automatically identify and adapt the controller: Basic: 100–120V/1ph/5–60Hz;Energy Savings Controller: 100–240V/1ph/50–60Hz & 12–24 VDC
NEMA 4 Standard Feature with Standard and Energy Savings Controllers

NOTES

Inlet Flow : Inlet flow are established in accordance with CAGI Standard ADF-200: Dual Stage Regenerative Desiccant Compressed Air Dryers-Methods for Testing and Rating. Conditions for rating dryers are: inlet pressure of 100 psig, inlet temperature saturated at 100° F.
Average purge flow rate is the amount of purge air used during the regeneration portion of the purge cycle (purge/repressurization valve open) plus the volume of air used to repressurize the tower after the purge/repressurization valve closes averaged over the cycle time.
At 100 psig, the average purge rate is: 14.4% (13.7% for regeneration + 0.7% for repressurization) of rated inlet flow for dryers operating on a 10 minute cycle; 15.5% (13.7% for regeneration + 1.8% for repressurization) for dryers on a 4 minute cycle.
Outlet Flow: To determine flow of air available at outlet of dryer, subtract purge flow from inlet flow.
