Fasmov Foam Cannon Car Wash Snow Foam Lance — 1L Bottle, Adjustable Foam & Brass Mixing Core

This foam cannon turns a compatible pressure washer into a high-foaming sprayer so you can pre-soak cars, trucks, driveways, roofs, and siding with soapy suds. The device combines a brass mixing core, an adjustable top knob, and a variable nozzle to control foam thickness and spray pattern. It requires a pressure washer that delivers at least 2.0 GPM and 1,000 PSI, supports temperatures up to 60°C, and accepts a 1/4" quick-disconnect fitting for fast attachment.

How does the Fasmov Foam Cannon create dense foam for washing?

The cannon uses a brass mixing chamber and an adjustable inlet to draw soap and mix it with high-pressure water for thick suds. Turning the top knob changes the soap-to-water ratio, while the nozzle setting changes the spray pattern, producing anything from a fine mist to heavy clinging foam.

• Quality brass core for consistent soap mixing and durability
• Top adjustment knob to control foam density from light to very thick
• Nozzle tuning for narrow to wide spray and different coverage
• Produces clingy foam that helps loosen dirt before rinsing

What pressure washer specs are required to run this snow foam lance?

To perform well the lance needs a pressure washer delivering at least 2.0 gallons per minute and a minimum of 1,000 PSI. The unit is rated for a maximum flow of 5.3 GPM and a maximum pressure of 160 bar, and it tolerates liquid temperatures up to 60°C.

• Minimum: 2.0 GPM and 1,000 PSI for effective foaming
• Maximum flow: 5.3 GPM; maximum pressure: 160 bar
• Temperature limit: 60°C (140°F)
• Connects via a 1/4" quick-disconnect fitting to most wands/guns

How do you use and adjust the foam lance for best results?

Fill the 1-liter bottle with warm water and the recommended car or exterior soap, attach the lance to your pressure washer wand using the quick connector, then spray while adjusting settings. Turn the top knob toward the "+" or thicker setting for heavy foam, and rotate the nozzle to refine the spray pattern for coverage or concentrated application.

• Fill reservoir with soap and warm water following manufacturer dilution guidelines
• Attach 1/4" quick connector to pressure washer gun or lance securely
• Adjust top knob for foam level; turn nozzle for spray width
• Rinse surfaces after dwell time appropriate for the cleaning task
