It is rated for a maximum flow of 2500 SCFM and an effective drying capacity of 15 SCFM based on 70 degrees F inlet temperature at 100 PSI. The desiccant vessel measures 3 x 3.5 x 6 inches (L x W x H) and holds approximately 3\/4 lb of silica gel desiccant. Maximum operating pressure is 150 PSI.\u003c\/p\u003e\n\n\u003cp\u003eDesiccant tower dryers use silica gel to adsorb moisture from compressed air, producing dew points significantly lower than refrigerated dryers can achieve. The C-DF12 is the smaller of the two Castair desiccant tower models, suited for low-volume instrument air drops, laboratory air supplies, or applications where moisture removal is needed at a specific point of use. A particulate prefilter and coalescing filter must be installed upstream -- oil contamination deactivates silica gel.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size:\u003c\/strong\u003e 1\/2-inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesiccant Type:\u003c\/strong\u003e Silica gel -- replaceable when exhausted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flow:\u003c\/strong\u003e 2500 SCFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Drying Capacity:\u003c\/strong\u003e 15 SCFM at 70 degrees F inlet, 100 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesiccant Capacity:\u003c\/strong\u003e 3\/4 lb silica gel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVessel Dimensions:\u003c\/strong\u003e 3 x 3.5 x 6 inches (L x W x H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure:\u003c\/strong\u003e 150 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesiccant Refill:\u003c\/strong\u003e Castair DSGB02 Silica Gel 1-Qt (2 lbs)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen to Use a Desiccant Tower Dryer\u003c\/h3\u003e\n\u003cp\u003eRefrigerated dryers typically achieve dew points around 35-40 degrees F. Desiccant dryers can reach -40 degrees F or lower. Use the C-DF12 for instrument air on sensitive pneumatic controls, air supply in cold outdoor conditions where in-line condensation would freeze, or process air where moisture causes product or equipment problems.\u003c\/p\u003e\n\n\u003ch3\u003eRequired Upstream Filtration\u003c\/h3\u003e\n\u003cp\u003eA 5-micron particulate filter and a coalescing filter must be installed upstream of the C-DF12.
