Custom Air & Gas Dryers & Filters

At times a unique application calls for a unique solution. For more than 60 years the employees of Van Air Systems have distinguished themselves by closely working with engineering firms, equipment distributors, OEMs, and end-users to design and manufacture customized air and gas dryers and filters.

Field Service & Application Consulting

In many industries compressed air and gas treatment equipment is vital to production. A malfunctioning compressed air dryer can cripple an entire production line. For natural gas producers, an underperforming dryer can lead to pipeline freeze-ups or failure to meet dew point specifications.

Desiccant Testing

All adsorbent desiccants—activated alumina, silica gel, molecular sieve—gradually decay in regenerative compressed air dryers. Desiccants are subjected to hydrothermal aging and mechanical stress during regeneration. Over time these forces diminish the moisture retaining capacity of the adsorbent material. Further, oil contamination occurs when pre-filters are not adequately maintained, permanently fouling desiccant beds. Typically, a bed of adsorbent desiccant lasts 3 to 5 years before needing replacement.

Compressed Air Treatment Seminars

As the oldest independent American manufacturer of equipment for the treatment of compressed air, Van Air is committed to educating compressed air users, process engineers, plant maintenance professionals, and equipment distributors. Every spring and fall Van Air hosts two-day seminars covering the theory and practice of compressed air treatment.
