Magnetic AP-MM Asphalt Release Foam System

Model # 977941

The Magnetic AP-MM Asphalt Release Foam System is a magnetic sensor 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 compressed air to drive a rugged Sandpiper air-operated, double-diaphragm pump which draws chemical concentrate and water from separate static tanks and blends them "on-the-fly" to create an accurately diluted solution. Rich, clinging foam is created by injecting compressed air into the solution to greatly expand volume and coverage ability. When a truck comes into range of the magnetic sensor, a delay timer allows the driver to position the truck under the foam bar before foaming begins and a run timer applies chemical for a pre-set time or until the vehicle leaves the foaming area, whichever is first.

Key Features
  • Projects asphalt release chemicals on to truck beds from a foam bar that attaches to an existing drive-through bar
  • Rich, clinging foam increases chemical contact time and coverage for maximum effectiveness
  • The rugged Sandpiper AODD pump draws chemical concentrate and water from separate static tanks and blends them "on-the-fly"
  • The magnetic sensor activated, adjustable, single-shot timer will delay for up to 6 minutes, allowing the driver to get in position, and then apply chemical for up to 6 minutes before shutting off
  • Magnetic sensor with adjustable sensitivity eliminates potential alignment issues associated with electric eyes (photocell sensors)
  • The driver remains in his cab and avoids the risk of slip-and-fall injury and chemical waste
  • Evenly coats the truck bed in just seconds, reducing run-off and chemical waste
  • A float valve assembly attaches to, and automatically refills, a user-supplied static water tank
  • Achieves a wide range of dilution ratios using a metering manifold to control chemical and water flow
  • Chemical resistant wetted components ensure years of outstanding performance with minimal maintenance
  • Available as a spray applicator (#977845)
  • See other Lafferty asphalt release equipment and industrial chemical applicators in Catalog 8
