FSX cleans diesel particulate filters for customers on either an as-needed basis or under contract.  We receive filters from throughout the United States.  FSX inspects, cleans, tests and returns the filters to the customer who sent it in.  We do not exchange or substitute filters.  All filters are recorded by serial number in our database with the associated results from cleaning.

1. Record owner and serial number
2. Inspected and test filter on FSX TrapTester; record defects, damage and test results in database
3. Perform Stage 1 pneumatic cleaning of the filter using the FSX TrapBlaster.  Inspect filter during cleaning process using built in filter failure diagnostic feature. Record defects.
4. Test filter on FSX TrapTester.  Compare results with FSX Baseline Matrix; determine status as Green Tag, Orange Tag, or Red Tag
5. If Green Tag achieved record results, repackage and return to customer.
6. If status is Orange Tag or Red Tag move filter forward into Stage 2 thermal cleaning using the  FSX TrapBurner
7. Perform second pneumatic cleaning on FSX TrapBlaster to blow out ash freed in Stage 2 thermal cleaning.
8. Test filter for air flow on TrapTester; record results.  Compare results with FSX Baseline Matrix; determine status as Green Tag, Orange Tag or Red Tag and attach tag with cleaning results
9. Record results in FSX database, repackage and return to customer.

FSX cannot and does not guarantee or warrant that we can achieve recovery of the filter.  Filters can fail for a variety of reasons as a result of operating conditions.  The primary source of failure is unusual thermal events that have caused sintering, failure of the cell walls or melting of the ceramic sub-strait.  Filters can also be damaged by dropping them, thermal shocking them, oil soaking, coolant soaking, chips and vibration.  Due to design and materials some filters last longer than others or can with stand higher temperatures.

FSX has an overall average cleaning success of about 95% of the filters.  A recovered filter reaches Green Tag or Orange Tag status as set by FSX statistical analysis.  Approximately 5% of the incoming filters will not move out of the Red Tag range for a variety of reasons or  have failed or been damaged prior to receipt.  These filters are Red Tagged and deemed un-cleanable.

Overall filter life decreases when impacted ash is left in the filter cells.  The deeper the impacted ash becomes the harder it is to remove in subsequent cleanings.  The risk of sintering increases when ash is left in the filter.  Ash stuck in the filter causes cold cells and leads to premature soot plugging.  The cleaner the filter is kept the longer the overall life.  FSX has repeatedly cleaned the same filters pulled annually on a preventative maintenance basis over four years and returned them to the Green Tag range every time.

Filters cleaned on pneumatic cleaning machines that do not clean each cell individually are more difficult to recover.

FSX cannot control the time between cleanings and makes no guarantees.  Filters can be re-plugged within hours if the engine is malfunctioning, operating temperatures are out of specification or if the wrong fuels or lubricants are used.   FSX has seen filters run 240,000 miles after cleaning and filters that re-plugged in two hours.  The ash that plugs a filter loads lineally in the filter based on engine hours and rpm.  The loading rate of ash will vary due to the lubricants used, engine condition, and fuel quality.  Usually it takes quite a period of time to plug a filter with ash.  Soot plugging can occur very quickly and is usually due to a very unfavorable operating condition such as low filter temperature or engine problems.

Retrofit filters without passive regenerations systems typically plug with soot much more often than engine systems equipped with active onboard regeneration systems.  Active regeneration systems have the ability to burn off accumulated soot and thereby keep the filter clear.

FSX typically performs the Stage 1 Pneumatic Cleaning on an incoming filter within 8 business hours of arrival.  If the filter needs a Stage 2 Thermal Cleaning the process time is about 12 hours.
Typical turn around times:
Stage 1 Pneumatic Cleaning – 24 hours
Stage 1 Pneumatic Cleaning plus Stage 2 Thermal Cleaning – 48 hours

Rush cleaning is available on request on a first come first serve basis.  An up charge will apply for rush orders.

DPF are very expensive filters and should be treated with care.  Make sure your shipment is adequately packaged for rough motor freight conditions.  The filter should be placed in a sealed bag or container.  Make sure the packaging protects flanges or rims from denting.  Do not leave the ceramic face exposed.

FSX will repackage the filter in the materials you sent it in.  If the packaging is deemed unacceptable by FSX shipping personnel the filter will be repackaged and additional charges will be passed on to the owner.

Do not put hot filters into plastic bags or other packaging materials that will melt.

FSX will provide basic repairs to a filter if needed.  Additional charges will be incurred for these services.  The types of repairs include:

• Patching damaged cells (limited to our professional judgment)
• Straightening bent rims
• Welding broken welds or broken rims or casing

Prices will be provided upon request.  Prices may vary due to filter size and filter design and whether the filter needs to go forward to a Stage 2 thermal cleaning.    FSX only moves a filter forward to a Stage 2 thermal cleaning if the filter did not reach Green Tag range with the Stage 1 pneumatic cleaning. FSX has the following charges:

• Stage 1 Pneumatic Cleaning – Green Tag
• Combined Stage 1 Pneumatic Cleaning and Stage 2 Thermal Cleaning  - Green Tag or Orange Tag
• Unsuccessful Cleaning Handling Charge:  $25.00 flat charge in most cases unless filter is over 16” in diameter x 27” tall  Note:  The cleaning charges under item #1 and #2 above are waived by FSX if we are unsuccessful in recovering the filter.  FSX believes if you did not get the enjoyment of being able to use your filter that we should not get the enjoyment of being paid. The nominal flat handling charge of $25.00 covers a small portion of the costs we incurred attempting to salvage your filter.
