Hankison HPR-35 Air Dryer

The Hankison HPR-35 is a high-efficiency refrigerated air dryer engineered for industrial compressed air systems, delivering 35 SCFM at a consistent 38°F pressure dew point. This unit is designed for contractors and technicians looking to remove moisture from air lines and prevent downstream equipment corrosion. As an direct replacement for HKN-HPR-35, HKN-HPRP-35, and K-8035 models, it integrates seamlessly into existing setups with 3/4" NPT connections and a standard 115V single-phase power supply. Using a smooth-bore copper tube-on-tube heat exchanger and a centrifugal separator, the HPR-35 captures liquid condensate efficiently across varying inlet loads. The non-cycling operation and static condenser design ensure quiet, reliable performance without the mechanical complexity of cycling units. Built with a rugged epoxy-coated steel cabinet and environmentally friendly R-134a refrigerant, this dryer provides the thermal stability required to protect pneumatic tools and sensitive air-driven machinery from water contamination and pressure drop issues.

• Stable ISO Class 4-5 Air Quality: Maintains a 38°F (+3°C) dew point to eliminate liquid water and prevent corrosion in pneumatic circuits.
• Efficient Condensate Removal: Equipped with a timed electric condensate drain and centrifugal separator for zero-moisture carryover.
• Contractor-Friendly Installation: Compact footprint with 3/4" NPT compressed air connections and 115V plug-and-play capability.
• Low Maintenance Design: Features a static condenser and non-fouling heat exchanger channels to reduce the need for frequent servicing.
• Durable Construction: Heavy-duty steel housing with an industrial epoxy finish for long-term resistance to harsh shop environments.

Is the Hankison HPR-35 compatible with my existing HKN-HPRP-35?
Yes, the HPR-35 is the specified replacement for HKN-HPRP-35 and K-8035 models, maintaining identical port sizes and electrical requirements for simplified field retrofits.

What type of refrigerant does this model use?
This unit utilizes R-134a, a globally accepted, CFC-free refrigerant known for its reliable heat transfer properties and stable operating temperatures.

Does it include an automatic drain valve?
The HPR-35 features a timed electronic drain valve that ensures consistent moisture discharge without manual intervention, critical for maintaining system integrity.
