DISTRIBUTOR-FIRST SUPPLY PARTNER · SINCE 1999 BRAND · GREAT LAKES AIR
US-made air dryers from Michigan, with filters to match, the treatment brand SPC specs and backs.
Made in Michigan. Built to spec.
Great Lakes Air has manufactured compressed air treatment equipment in Westland, Michigan since 1983, founded on a straightforward premise: that declining quality in the US compressed air industry was a problem worth fixing from the ground up. Its dryers are built at that Michigan facility, the same one it has operated since founding.
The product line is deliberately complete: refrigerated drying from 10 to 13,500 SCFM, regenerative desiccant drying down to −100°F pressure dew point, matched filter housings, and a PSA nitrogen generator line. That breadth means a plant engineer can source a full air treatment package from one brand on one purchase order. Great Lakes Air backed its quality claim with a 5-year warranty on standard refrigerated dryers, at a time when 1-year coverage was considered long. The company says that warranty covers the entire dryer except maintenance items, and that it has been supported since 1983. Its brochures now describe a 5-2-1 warranty on regenerative and high-inlet-temperature dryers.
Great Lakes Air is the dryer brand SPC reaches for first.
Refrigerated dryer, desiccant dryer, filter housings, and nitrogen generator come from one brand.
Made-in-USA is a requirement on an increasing number of government, defense, and infrastructure contracts.
Purge air at 7% or less.
Zero purge air in blower-only mode.
Main-line flows; 165 PSIG, 450°F housing rating.
On-site nitrogen from the same factory as the dryers.
General plant air, +38°F class dew point.
Lower energy at part load.
Systems above standard line pressure.
Hot inlet air up to 180°F.
Central plants.
General Manufacturing → Plant air drying and filtration for production environments of all types. 
Food & Beverage Processing → Refrigerated and desiccant drying for food-safe compressed air applications. 
Automotive Manufacturing → Dry, clean air for paint booths, robotics, and pneumatic tooling. 
Metalworking & Fabrication → Reliable drying for machining, welding, and finishing lines. 
Packaging & Printing → Stable dew-point air for packaging machinery and print processes. 
Pharmaceutical, Medical Device & Laboratory → Low-dew-point, filtered air where air quality is part of the process spec. GRN non-cycling refrigerated dryers cover 10–3,000 SCFM for general plant air. High-capacity GMNF/GMNX steps up to 13,500 SCFM for large central-plant systems. GPS heatless desiccant covers 25–3,000 SCFM; GEH and GBS heated and blower-purge cover 100–25,000 SCFM for continuous high-flow instrument-air duty.
A +38°F pressure dew point for general plant air calls for a GRN refrigerated dryer. Applications needing −40°F (instrument air) or −100°F (critical process air) move to the GPS heatless or GEH/GBS desiccant lines respectively.
Standard lines to 150 PSIG work with the GRN/GPS base series. Systems running to 650 PSIG step to the GHRN high-pressure refrigerated dryer.
Standard refrigerated dryers are rated to 100°F inlet. If the compressor room or after-cooler delivers hotter air, the EDR high-inlet-temp series is rated for inlet air up to 180°F.
