the diesel particulate filter flange 50 diesel particulate filter coupler fasteners 64 fasten the adaptor flange 48 and diesel particulate filter flange 50 together the inlet 46 of the diesel particulate filter 42 connects to an ash collector 54 such as a shop vac bag or other dust reservoir that allows clean air to vent from the ash collector 54 and the diesel particulate filter cleaning apparatus 10 the inlet 46 is preferably at least partially enclosed within ash collector 54 to prevent diesel particulate material from escaping into the environment during cleaning once the apparatus is assembled the air supply 26 is opened and air flows into the air supply line 28 air next flows from the air supply line 28 into the air chamber 12 in one embodiment the air flows through the fitting 30 and is directed into the air chamber line 19 and the vibrator line 34 the air chamber 12 and vibrator 15 pressurize in another embodiment the air flows only into the air chamber line 19 to pressurize the air chamber 12 the air chamber regulator 20 can be set to a desired air chamber pressure to regulate the flow of air into the air chamber 12 the pressure in the air chamber 12 can range from about 10 psi to about 90 psi for the air chamber 12 although a maximum pressure is the amount of pressure that can be used without degrading the diesel.
