FLASH Restoration and thermal baking use two different workflows: controlled fluid-based cleaning with restriction testing versus staged heating, cooling and compressed-air ash removal.
FLASH Restoration uses controlled fluid circulation and air-pressure pulses to loosen and remove removable soot and non-combustible ash from eligible components. Thermal cleaning uses staged heating, cooling and compressed-air cleaning.
Thermal Baking Oven
Thermal cleaning oxidizes soot and hydrocarbon residue during a controlled heating cycle. Mineral ash does not burn away, so a complete workflow may also require pre-cleaning, controlled cooling and final compressed-air removal.
Loose ash and surface contamination may be blown out with compressed air prior to heating.
Programmed kiln temperature cycles oxidize residual soot and hydrocarbon deposits into ash.
The filter undergoes a controlled cool-down period to prevent thermal shock before handling.
Additional pneumatic pulse cleaning is required after baking to blow out the oxidized ash deposits.
Workflow Consideration: Equipment-specific cycle times vary. For example, the official Donaldson thermal regenerator manual specifies a seven-hour heating and cooling cycle before final pulse cleaning—illustrating why thermal workflows generally require more processing stages than FLASH Restoration.
DPF BOX uses FLASH Restoration because it combines controlled fluid-based cleaning with documented restriction testing in a workflow designed for commercial turnaround. For eligible components, the process helps remove removable soot and non-combustible ash without relying on a prolonged kiln cycle.
Many eligible filters can be processed in approximately two hours, subject to component condition and current workload.
Controlled fluid circulation helps loosen and remove non-combustible ash that cannot be burned away through regeneration.
Pre-cleaning and post-cleaning restriction readings are compared on a flow bench before the filter is returned.
Cracked, melted, heavily oil-saturated or structurally damaged components may be unsuitable for cleaning.
A loaded filter can contain far more than surface soot. The dark discharge visible in this real DPF BOX service footage includes loose soot, compacted ash and accumulated contamination being removed from eligible channels during the FLASH Restoration process.
See soot and suspended deposits leave the component during cleaning.
Controlled circulation is intended to reach restricted internal passages, not only the visible filter face.
Restriction readings are measured and compared on a flow bench before and after service.
Every filter undergoes an initial physical inspection before processing. If the ceramic substrate is intact and removable contamination is causing the restriction, FLASH Restoration may significantly reduce excessive backpressure. However, damaged or melted substrates cannot be restored by any cleaning method.
