AQUEST CORPORATION designed and installed a three-stage dust collector with rotary screen separator, rotary drum filter, and baghouse after-filter at the largest manufacturer of wool blankets in North America. The system was designed to alleviate employee respiratory complaints generated by their non-woven needle-punch operations. To meet exacting customer requirements, Aquest designed a system to handle wool fibers of various sizes. The system cleaned the facility air, recycled reusable material back into the process, and returned exhaust air back into the building. The collector was equipped with the necessary fire and explosion protection devices, including: a spark detection and suppression system, backdraft damper, and high-speed abort gate.
