1. A process for cleaning parts comprising:
connecting a vacuum source to a port in a first air pulse generator housing;
connecting a source of pressurized air to another port in said housing;
alternately connecting said vacuum port or said pressurized air port in rapid succession to an outlet port;
connecting an outlet fluid passage to said outlet port to create a rapidly reversing air flow therein; and
completely enclosing one or more parts in a tooling cavity; and
connecting said tooling cavity to said outlet fluid passage to receive said rapidly reversing, air flow to and form, said tooling cavity
whereby rapidly reversing high velocity air flow pulses are directed into said tooling cavity to clean said enclosed one or more parts.
