Abstract
A quick release aerator is provided for discharging intermittent bursts of pressurized air into a storage container to implement material flow. The unit includes a piston and valve assembly disposed internal to a pressure tank. The assembly features one or more vent ports defined through the sidewalls of a cylinder to allow the passage of pressurized air from the tank to an outlet orifice. The total area of the vent ports equals or exceeds the area of the exhaust port, thereby maximizing the effect of the burst of pressurized air.
