Shick Esteve’s Insertable Quick Change (IQC) Filter utilizes high-efficiency spun bond polyester filter elements with ePTFE membrane. The unit is ideal in areas with height restrictions and on top of use bins and silos to help keep your plant dust free. The unit’s filter elements have a 99.9%+ efficiency rating. Its compact design makes it ideal for silos, receivers, dust collectors and bin vents, a better alternative in comparison to traditional bag and cage filters. Change of filters occurs from the clean air plenum. This eliminates confined space permitting or entry procedures.
