    Donaldson Company, Inc. Standard Equipment Inlet Filters are installed in the correct orientation and direction during servicing. Delta P-C01 Control The DFEP ships with a Delta P controller to monitor differential pressure between the clean-air and dirty-air plenums and provides The Delta P control and a pulse control timer manage pulse cleaning from user established High and Low Pressure Set Points.

  • Page 7: Dust Bin

    Dust Bin The standard dust bin is located below the hopper to collect dust removed from the air stream. The dust bin is sealed to the hopper discharge with a convenient clamping arrangement which lifts the dust bin against a sealing gasket on the base of the hopper to ensure a dust tight seal during operation.

    The DFEP can be equipped with factory installed explosion relief panels to support a process owner's combustible dust mitigation strategy. Explosion vent sizing follows NFPA-68 formulas assuming outdoor location of the collector, with no duct or obstruction on the explosion vent panel(s). Contact Donaldson Torit for explosion venting requirements for other conditions. Remote Mounted Controls The DFEP controls can be provided external rather than internal to the collector if desired.

  • Page 9: Operation

    Operation During normal operation, dust-laden air is drawn into the collector through a duct connected to the inlet box, near the top of the collector. The dust-laden air is then directed downward through the collector body where heavier dust falls directly into the hopper. air passes into the clean-air plenum where it is drawn through the fan and is discharged through the clean-air outlet.
