The DART™ AP-MM Foam System is a push button activated foam applicator that mounts to a user-supplied drive-though arch for applying asphalt release chemicals to truck beds. It is designed for facilities with low or fluctuating water pressure. This system uses a rugged Sandpiper air-operated, double-diaphragm pump to draw chemical concentrate and water from separate static tanks and blend them "on-the-fly" to create a diluted solution. Rich, clinging foam is created by injecting compressed air into the solution to greatly expand volume and coverage ability. When the driver pushes the button to activate the system, a delay timer allows the driver to position the truck under the foam bar before foaming begins and a run timer limits application to a pre-set time period.
