3-Bar Pump Fed Truck Foam Arch

Model # 910930-PF

The 3-Bar Pump Fed Truck Foam Arch is an adjustable, drive-through foam applicator for washing large vehicles. This unit receives ready-to-use chemical solution from a user-supplied central chemical feed system and injects compressed air to greatly increase volume and coverage ability. Rich, clinging foam is projected from multiple nozzles for complete coverage. The solution flow rate and foam consistency for each foam bar can be adjusted "on-the-fly" during operation.
