The FNA GROUP 80271 is a high pressure foam cannon designed for use with cold-water pressure washing systems. It attaches to compatible gas or electric pressure washers and delivers thick, clinging foam to target surfaces before rinsing. The adjustable foam control knob on top lets the operator dial in the desired foam output level to match the cleaning task. The dense foam film holds cleaning solution against the surface longer, which helps loosen stubborn dirt and grime without requiring excessive manual scrubbing. This cannon is suited for professional contractors and service technicians who rely on pressure washing as part of routine maintenance and detailing work.
The 80271 foam cannon is rated for cold-water pressure washers operating between 1600 psi and 4000 psi, covering a wide range of residential and light commercial units. Typical applications include vehicle washing, exterior siding cleaning, boat and RV maintenance, and UTV detailing. It is commonly used by mobile detailing professionals, fleet maintenance crews, and exterior cleaning contractors who require a reliable foam pre-soak step before high-pressure rinsing. The cannon connects to standard cold-water gas or electric pressure washer setups and does not require specialized fittings beyond those typical to the platform.
Compatible with most cold-water gas or electric pressure washers operating between 1600 psi and 4000 psi. Verify inlet fitting compatibility with your specific pressure washer wand or gun before installation.
Installation is performed by pressure washing technicians or experienced operators familiar with pressure washer accessory connections. Relieve all pressure from the system and shut off the machine before attaching or removing the foam cannon. Ensure the cannon inlet fitting matches the quick-connect or threaded outlet on the spray gun before applying pressure. Do not exceed the rated maximum pressure of 4000 psi during operation.
