Shop vac

A vacuum connectable to a supply of compressed air, comprising:

• a canister having an upper plate and a lower plate and a cylindrical wall;
• a handle extending at a proximal end from the upper plate of the canister, the handle including an adapter at a distal end for connecting to a supply of pressurized air and a passage for communicating the pressurized air into the canister;
• a nozzle within a compartment inside of the canister and connected to the handle for transferring the compressed air thereto, the nozzle accelerating the compressed air through a conduit with a smaller cross-sectional area than the handle;
• an orifice plug inside the compartment and spaced from an outlet of the nozzle, the orifice plug passing the accelerated high pressure gas thereinthrough to create a low pressure condition in the compartment;
• a muffler connected to the orifice plug and extending outside of the canister for expelling the high pressure air to the environment;
• a flow control device for isolating the compartment inside the canister with a collection area inside the canister;
• a drain pipe connected to the bottom plate of the canister, including a actuator for opening the drain pipe to empty contents collected in the collection area;
• a vacuum tube extending from the canister at the bottom plate and in fluid communication with the collection area;
• and
• a pick-up device connected to the vacuum tube, the pick-up device including first and second plates and a flange connectable to the vacuum tube, and further comprising first and second wipers having a protruding tip that extends beyond the first and second plates, the protruding tips cooperating to form a V-shaped gap.
