Foam Cannon Orifice Size Explained: Why It Changes Everything
Small parts. Big misunderstandings.
Estimated Reading Time: ~9 minutes
Orifice size is one of the most misunderstood aspects of foam cannons.
Many users swap orifices expecting dramatically better cleaning results — only to end up with foam that looks different but doesn’t actually work better.
This guide explains what foam cannon orifice size really does, what it doesn’t do, and when changing it actually makes sense.
Why people search “foam cannon orifice size”:
- They want thicker foam
- They’re troubleshooting weak foam output
- They’ve heard smaller orifices are better
This article explains the reality.
Key Takeaways
- Orifice size affects flow, not chemistry
- Smaller orifices can increase foam density
- Wrong orifice can reduce performance
- Soap and setup matter more than hardware swaps
What the Orifice Actually Does
The orifice controls how much water flows through the foam cannon.
This directly affects:
- Water-to-soap ratio
- Foam density
- Spray pressure at the nozzle
It does not change cleaning chemistry.
Common Foam Cannon Orifice Sizes
- 1.1 mm: Lower flow
