Honeywell's economical filtration process continuously captures undesirable air borne odor or gas contaminants from an air stream through unique trilobal wicking fibers. The special fibers form channels--impregnated with appropriate solid (preferably carbon or zeolite particles) and/or liquid chemistry. Wicking fibers are formed into a filter element. The contaminant removing chemisorptive liquid is held in the channels through capillary action. Any undesirable odor molecules within the chemisorptive liquid are either conveyed from the cleaned air stream or are chemically altered. This novel system is well suited for automotive and aircraft cabin odor control and many other applications such as gas masks, microelectronic assembly clean rooms, flue gas scrubbers, or protective fabrics.
Benefits SummaryHoneywell's unique odor removal system provides a compact, economical air filter with increased flow rates, increased efficiency at high humidities, a relatively low pressure differential, and increased removal efficiency over time compared to conventional carbon based odor filters. The extremely high odor absorbing capacity is many times greater than activated carbon. The wicking fiber filter can be impregnated with further additives to remove a broader range of gases than activated carbon. This nonmechanical, wicking fiber system--operating in a steady state condition, provides for the continuous removal of selected gas molecules without a pump or other device to move the chemisorptive liquid. more
Development SummaryThe trilobal fiber is commercially available. The odor filter has been tested and confirmation data generated in a laboratory setting. more
IP SummaryThis technology is supported by 2 US patents. The most recent year of issue is 1999. more
