The FS-Curtis DHB Series is a line of blower purge desiccant dryers designed to improve air system efficiency by the use of a dedicated axial blower to regenerate the off-line desiccant tower. They do not use compressed air as purge air and deliver full supply-side compressor capacity. These dryers are capable of dew point performance to -40°F.

Additionally, these blowers operated with industrial level high capacity. The low-watt density heater helps with energy saving requirements and aids in desiccant aging. The premium grade desiccant beads enhance the surface area as well as having high crush strength. The electrical enclosures are rated to NEMA 4.
