8GDED-IOM-215-Aavoid any contact with the operating fan. Under no circumstances should the fan ever beallowed to operate when any of the access panels on the dust collector, or the silencer, havebeen removed. The fan must be disconnected and locked out prior to the performance ofany maintenance work, see paragraph 2.4.2.6 Safety GuardsThe dust collector cabinet prevents access to the fan inlet. All access panels shallremain bolted in place while the fan is operating. Prior to the removal of any access panels,the electrical power to the collector shall be disconnected and locked out, see paragraphs2.4 and 2.5. After electrical power is disconnected, the fan wheel will continue to rotate fora period of time before coasting to a stop. Do not access the fan until the fan wheel hascome to a complete stop.3 GENERAL PRODUCT INFORMATION3.1 DescriptionThe OptiFlo RC is a complete pulse-jet cartridge collector system capable of providingcontinuous on-line cleaning. This cartridge collector utilizes high efficiency pleated filterelements arranged in a horizontal arrangement. Dust laden air enters above the filterelements and moves in a true down flow direction between the filters. The airstream passesthrough the media as the dust is collected on the filter media. The clean air then movesthrough the tube sheet section and into a clean air plenum at the rear of the module.3.2 Purpose and intended useThe OptiFlo RC is intended to be used for relatively dry nuisance dusts, with loadingsgenerally less than 3 grains per cubic foot (7 g/m3). Typical applications an OptiFlo RC isused for include weld fume, laser tables, thermal spray, chemical, pharmaceutical, and foodprocessing. The cartridge that is used in the OptiFlo RC should be suitable for the intendedapplication.The REDClean® N cartridge is suitable for most applications where the OptiFlo RC isused. Contact AAF International for assistance on a cartridge design for your application. Itis recommended that you use only AAF International cartridges on AAF Internationalequipment.3.3 Normal OperationDuring normal operation, air enters the OptiFlo dust collector through the high inletand moves downward through the dirty air plenum, in true “downflow” fashion. The cleanedair passes through the filter elements, while dust is collected on the outside surfaces of theelements. Clean air flows through the center of the elements into the clean air plenum,where it exits through the clean air outlet.
