Our Process

Severe duty Diesel Particulate Filters [DPF] are baked in an extraction oven at varying time cycles and temperatures. A DPF will bake at a temperature between 800 – 1200 degrees for a length of time between four to eight hours [not including ramp up and cool down cycles]. This baking process reduced the particulate matter [soot] into ash.  This ash is easier to extract from the filter than the particulate matter in its “soot” form.

​

  After the filter is baked, it is placed in a blast cabinet.  This cabinet is a Proprietary design from Enviromotive Inc.. This blast cabinet pneumatically forces air into each individual cell at the exit side of the filter, while a high power vacuum draws the particulate matter from the inlet side.  Air is expelled through each cell until a reasonable amount of the particulate matter is removed from filter.  The filter is then tested for airflow with a MAGNAHELIC gauge – that measures pressure drop in inches of water column.  Acceptable airflow levels per Manufacturer specifications are required for each DPF service.  If a DPF does not register acceptable air flow [after a full service] it will go through another full service cycle [Bake and Blow out] until it measures an acceptable air flow level or the filter will be deemed unfit for use.
