Filter Dust Collector (FDC) units from Novatec, Baltimore, reportedly provide a higher level of vacuum-pump protection than standard cyclone dust collectors. The three PTFE-coated cartridge filters are 99% efficient to 1 micron and remove more fines than standard cartridge filters while minimizing clogging.
FDC Series Models 50 & 124 (measured in ft² filter areas) are suitable for use with 2-4-in. OD material conveying lines. Filter areas are said to be 15-24% larger than competitive models. They have stainless-steel construction and compressed-air filter cleaning.
Tangential air/dust entry maximizes dust separation from the airstream before it reaches the filters. An internal material deflector/flapper check valve with seal deflects incoming material away from the filters and allows the receiver to be used in common-material-line systems. Fines are emptied via a quick-disconnect catch bin with cradle support (no tools required).
