Veloci MTM Hydro PF22.2 Foam Cannons
Complete Guide to Veloci’s PF22.2 Foam Cannons
In the world of pressure washing and auto detailing, foam delivery isn’t just about looks—it’s about performance, coverage, and efficiency. The Veloci PF22.2 Foam Cannon is widely regarded as the gold standard in professional-grade foamers. Built in Italy with precision engineering, it delivers thick, clingy foam while offering unmatched adjustability and reliability.
Whether you’re foaming down a ceramic-coated vehicle, degreasing equipment, or performing a touchless wash, the PF22.2 turns your chemical into an ultra-consistent blanket of foam—and helps you do it faster and cleaner.
What Is the PF22.2 Foam Cannon?
The PF22.2 is Veloci’s flagship adjustable foam cannon, designed for use with pressure washers to deliver rich foam using a wide range of soaps and degreasers. It's known for its build quality, adjustability, and chemical efficiency, and is often the go-to choice for professional detailers and fleet washers.
Made in Italy by PA (Pulsar Atomizer) and distributed by Veloci Performance Products, the PF22.2 is a refined and rugged tool that outperforms budget foamers in both precision and longevity.
Key Features
- Adjustable spray fan – vertical or horizontal orientation
- Adjustable chemical injection knob – dial in your soap ratio
- Heavy-duty brass and stainless steel construction
- Rated up to 1,100 PSI min. and 4,000 PSI max
- Handles up to 5.3 GPM and 140°F
- Wide-mouth, transparent bottle – 1-liter HDPE bottle with ratio markings
- Quick connect compatible (1/4” plug or M22 options)
How It Works
The PF22.2 uses the venturi effect to draw chemical from the bottle into the high-pressure stream from your pressure washer. It mixes water and soap internally, then atomizes the solution at the nozzle to create dense foam.
It requires a minimum of 1.4 GPM @ 1,100 PSI to operate properly—making it compatible with most electric and gas pressure washers used by professionals.
Setup Instructions
- Attach to your pressure washer wand or gun using a 1/4" quick connect.
- Fill the bottle with your soap or chemical solution—usually pre-diluted based on product instructions.
- Adjust the fan pattern using the front nozzle collar.
- Set your chemical draw using the top injection knob—clockwise for leaner mix, counterclockwise for more soap.
- Begin foaming—start from the bottom up for even coverage and dwell time.
Recommended Applications
The PF22.2 is ideal for:
- Auto Detailing – Pre-washing, contact wash prep, ceramic coating maintenance
- Fleet Washing – Foaming semis, trailers, heavy equipment
- Touchless Washing – Pair with Chem-X Stars + Stripes or Old Glory
- Marine + RV Cleaning – Exterior prep with high-cling foam
- Industrial Cleaning – Degreasers like D-Lime 90 or Heavy Duty
Why the PF22.2 Over Standard Foam Cannons?
| Feature | Budget Foam Cannon | Veloci PF22.2 |
|---|---|---|
| Build Material | Mixed plastics/brass | Italian brass + stainless |
| Fan Control | Fixed or sloppy | Precision horizontal/vertical |
| Injection Control | Basic or none | True metering adjustment |
| PSI/GPM Range | Narrow compatibility | 1.1k–4k PSI / Up to 5.3 GPM |
| Longevity | 6–12 months typical | 2–5+ years with maintenance |
The PF22.2 isn't just built better—it sprays better, lasts longer, and wastes less chemical, especially when paired with high-performance soaps like those in the Chem-X lineup.
Tips for Best Performance
- Use distilled or soft water if your area has hard water—it helps with foam quality
- Clean the internal mesh filter occasionally to prevent clogging
- Use the correct orifice size—1.25 mm is standard, but a 1.1 mm orifice may improve foam at lower GPM (e.g., electric washers)
- Avoid overtightening the top collar—snug is sufficient for sealing
Common Pairings
| Soap or Chemical | Dilution in Bottle (Starting Point) | Use Case |
|---|---|---|
| Stars + Stripes | 1:10–1:15 per soap (split bottle) | Touchless 2-step wash |
| Old Glory | 1:10–1:15 | Ceramic-safe pre-wash |
| Snake Oil | 1:20–1:30 | Hydrophobic ceramic topper |
| Heavy Duty | 1:5–1:10 | Degreasing engines/equipment |
| D-Lime 90 | 1:5–1:10 | Asphalt, tar, rubber removal |
Always test and adjust based on surface conditions and foam preferences.
Maintenance Tips
- Rinse after each use by filling the bottle with clean water and running it for 20–30 seconds
- Inspect O-rings and seals—replace as needed
- Clean orifice nozzle if you notice foam thinning or jetting
- Store upright to prevent bottle warping and chemical backflow
Final Thoughts
The Veloci PF22.2 Foam Cannon is a staple in the arsenal of professional detailers and wash operators. It offers precision, power, and durability that far exceed generic foamers—making it one of the most worthwhile upgrades in any pressure wash setup.
When paired with Chem-X soaps and proper technique, you’ll get more foam, better coverage, and faster results—every single time.
