Two primary efforts define the DFTI (Digital Flow Technologies, Inc.) response to the HSARPA requirements to develop a lower cost, more efficient, high (1000 liters/min) volume flow rate concentrator that requires lower power than the extant concentrator designs. The first of these is to create an operational ¡§pre-concentrator¡¨ that will deliver a jet flow of air-plus-particles with the particulates (aerosols) concentrated at the jet centerline. This flow, delivered to a conventional concentrator tube provides a higher efficiency of operation given this centerline concentration. This prototype will be developed and proof tested with aerosol samples. The second effort will extend the initial design elements of the DFTI Concentrator System (described herein) that provides a dramatic reduction in the required power at a lower system cost. These specific extensions of the initial design elements (as described in this proposal) will be preparatory to the construction of a system in Phase II.
