Van Air Systems D-50-3

Van Air Systems D-50-3 is a deliquescent compressed-air dryer rated at 50 SCFM, providing approximately 20°F of dewpoint suppression — typical pressure dewpoint around 75°F in summer service conditions. Maximum inlet pressure: 250 PSI; minimum: 50 PSI. Connections: 3/4 NPT female. Weight: 60 lbs. No electricity required; single-pass salt-bed design absorbs moisture through chemical reaction with deliquescent desiccant tablets. Lowest capital and operating cost of any dryer technology for remote or outdoor installations where sub-freezing dewpoint is not required. Salt cartridge replacement is the main recurring cost. Suitable for remote pneumatic tools, outdoor pipelines, and work sites without electrical power. Note: Van Air Systems D-series catalog uses alphanumeric suffixes by SCFM flow (e.g., D8 = 50 SCFM per Van Air documentation); D-50-3 does not appear in the verified series lineup and may encode a pressure or connection variant. Confirm current model number with Van Air Systems before ordering. Price: approximately ,890.
