If you think that this compressor dryer package looks like it came from outer space you wouldn’t be far off. The unit shown here was designed for NASA for use with the space shuttle just before take-off.

NASA Dryer
(NASA Compresssor / Dryer)

It is the combination of many familiar components (air compressor, desiccant dryer to name a few) with the additional elements of NEMA-4 (weather-proof) and NEMA-7 (explosion-proof) requirements - all on a portable platform.

The point is that when NASA needed a reliable custom solution they came to General Air Products, Inc.

Many times the custom needs of our customers are just a few simple steps from our standard units. Maybe you have space constraints in the compressor room. Maybe you are working with an extra large system or you need more air storage than our standard units offer - we can help.
