Frequently Asked Questions
What size air compressor is the Hankison HPRB7-A designed for?
The Hankison HPRB7-A is rated for 7 SCFM and is commonly paired with small reciprocating air compressors in the 1 to 3 HP range. Proper sizing is important because an oversized compressor can overwhelm the dryer and reduce moisture removal performance.
Can the HPRB7-A be used with a rotary screw air compressor?
Yes. The HPRB7-A can be used with a small rotary screw compressor provided the compressor's delivered airflow does not exceed the dryer's 7 SCFM capacity. Matching dryer capacity to compressor output helps ensure consistent dew point performance.
How does a refrigerated air dryer improve compressed air quality?
A refrigerated air dryer cools compressed air, causing moisture vapor to condense into liquid water that can be removed from the system. This process helps prevent rust, corrosion, water contamination, and premature wear in downstream equipment.
Is the Hankison HPRB7-A difficult to install?
No. The dryer utilizes a standard 115V electrical connection and 3/8-inch MNPT air connections, making installation straightforward for most shops and maintenance facilities. Its compact design also allows installation in locations where floor space is limited.
What industries commonly use the Hankison HPRB7-A refrigerated air dryer?
The HPRB7-A is frequently used in woodworking shops, automotive service facilities, laboratories, maintenance departments, and light manufacturing environments. Any application requiring dry compressed air can benefit from refrigerated air dryer protection.
Can the HPRB7-A help protect air tools and pneumatic equipment?
Yes. Removing moisture before compressed air reaches downstream equipment helps reduce internal corrosion and water-related damage to air tools, valves, cylinders, and spray equipment. This can significantly extend equipment life and improve reliability.
How often does the HPRB7-A require maintenance?
Routine maintenance is minimal and generally includes cleaning condenser surfaces, verifying adequate airflow around the dryer, and periodically inspecting the condensate drain. Following recommended maintenance procedures helps maximize performance and service life.
Is a refrigerated air dryer better than a desiccant dryer for a small workshop?
For most small workshops, a refrigerated dryer like the HPRB7-A provides excellent moisture removal while maintaining lower operating costs than a desiccant dryer. Desiccant dryers are typically reserved for applications requiring extremely low pressure dew points.
What are the benefits of using R513A refrigerant?
R513A is an environmentally friendly refrigerant with a lower global warming potential than many older refrigerants. It provides efficient cooling performance while helping facilities meet modern environmental standards.
How do I know if the HPRB7-A is the right size for my compressed air system?
The best way to size a refrigerated air dryer is to compare the dryer's rated SCFM capacity to your compressor's actual delivered airflow. If your compressor produces 7 SCFM or less under normal operating conditions, the HPRB7-A is typically an excellent fit.
