Explosion Relief Panels
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. Situations such as combustible dusts
may require controls to be mounted at a remote location some distance from the dust collector. This option cannot be pre-wired at
the factory, so additional wiring is required during installation.
Delta P Plus Control
The Delta P Plus offers the same features as the Delta P control with additional pulse cleaning options. The Delta P Plus control
allows an operator to include a pulse cleaning cycle after the collector is shut down (after-shift cleaning), either in addition to, or
instead of, pulse cleaning while the collector is operating.
For complete information, see the current Delta P Plus Installation, Operation, and Maintenance manual.
A back draft damper may reduce the potential for dust to migrate from the collector inlet when after-shift cleaning is
active.
Extended Capacity Dust Bin
An extended capacity dust bin may be available to provide additional temporary dust storage for situations with heavier dust
loading and does not alter the overall collector height.
Collector Options
Top Mounted Junction Box
The DFEP ships with internal wiring pre-wired at the factory. The top mounted junction box provides the terminal block interface
between the internal wiring and the site-specific incoming wiring. Please refer to the wiring diagram print shipped within the
internal electrical controller enclosure for wiring details.
