Now be able to clean large Cummins, International, PACCAR, and Volvo Closed-End DOCs.

The tilted DOC adaptor plate will help you accommodate the new EPA 2017 and newer DOCs that are too large to rotate in the TrapBlaster. DOCs are much easier to clean than DPFs because the cells are open all the way through the filter so they can still be cleaned from one side by tilting the DOC using this adaptor plate.

Note: Cleaning these closed-end DOCs is accomplished by using only the lower air nozzle.
