Things To Consider

Cross-Reference Alternatives

Hankison's MPNs cross individual references to the equivalent Ingersoll-Rand, Speedaire and Parker model numbers. So, if you are looking for competitor items that are either out of stock or obsolete, chances are Raptor Supplies has the equivalent Hankison air dryers available. Customers can also cross-reference most products using the last 5 digits of the model numbers.


Hankison air dryers are medium & large in size and supplied in multiple pieces, therefore require careful packaging as some products might get damaged while shipping. Hence, they are delivered by air freight and not courier shipment for minimum downtime.

About Hankison

The company's catalogue includes refrigerated, desiccant & membrane air dryers, bypass valves, mist eliminators, compressed air filters, water separators, breathing air purifiers and condensate drains. The brand's high-quality pneumatic bypass valves are widely used in traditional hydraulic systems for maintaining pressure in a system by diverting a portion of the flow. These SPX Hankison valves are compatible with both gases and liquids and have maximum working pressure and operating temperature of 200 psig and 120 degrees Fahrenheit, respectively. Hankison's ISO Class 6 HIT Series refrigerated compressed air dryer is designed to remove water vapour from the air stream by passing it through a heat exchanger to condense out the moisture. Hankison air dryers can provide high-temperature air (up to 180 degrees Fahrenheit) with a maximum flow of 125 cfm. They feature a two-stage separator / filter, a reliable air-operated condensate drain, maximum pressure of 250 psi and an automatic refrigeration temperature control system. Choose from a wide range of these compressed air dryers, based on different voltage ratings and pipe sizes, along with parts kits for maintenance of dryers on Raptor Supplies.

The filters come with coated, closed-cell foam sleeves to resist chemical attacks from acids and oils, ensuring high efficiencies by preventing re-entrainment of coalesced liquids. They have chemical-resistant end caps and silicone-free configuration. These units include 7 grades:
  • Grade 1 oil vapour removal filter
  • Grade 3 maximum efficiency oil removal filter
  • Grade 5 high efficiency oil removal filter
  • Grade 6 desiccant dust removal after-filter
  • Grade 7 air line filter
  • Grade 9 separator / filter
  • Grade 11 impact type moisture separator
  • Frequently Asked Questions

    What is the working principle of refrigerated air dryers?

    • The fundamental idea behind refrigerated air dryers is to quickly chill, condense, and drain moisture from the air to remove humidity.
    • Warm, humid air is drawn into the dryer which quickly reduces its temperature in a refrigeration unit to roughly 3 degrees Celsius (37.4 degrees Fahrenheit).
    • The air's water vapour condenses into pure water at this temperature, which gathers in a water trap and is supplied to the discharge lines.
    • In a condenser, the hot, gaseous refrigerant is cooled and replenished. Through an outlet, the warm, dry air in the chamber is supplied once again.

    What are the factors to consider while choosing an air dryer for my air compressor?

    • Maximum airflow in standard cubic feet per minute (scfm)
    • Inlet air pressure
    • Inlet air temperature
    • Ambient air & water temperature (if the condenser is water-cooled)
    • Desired pressure dew point
    • Utilities & tools required
    • Process of installation

    What causes air dryer failure?

    Blockages, leaks, electrical problems and damaged components may cause air dryers to malfunction.

    What is the difference between a cycling and a non-cycling air dryer?

    The sole distinction between them is the dryer in the open vs closed facility. While cycle dryers switch on and off in response to demand, non-cycling refrigerator dryers are made to function continuously.
