PVDF Ozone Injector for Small Flow Applications
This is our smallest ozone injector, built for tight spots where standard units won’t fit. It’s the pvdf venturi injector for ozone water you need for point-of-use jobs, a compact small flow venturi mixer 0.25 t h for low-volume setups, and a reliable ozone injection fitting 4mm barb for small pipe systems.Ozone Gas-Liquid Mixers
This little unit, at a glance
- Total length: just 57mm — fits under sinks, inside countertop machines, or right next to a fish tank
- Water flow range: 0.05 to 0.25 tons per hour, perfect for small-scale systems
- Material: 100% PVDF, made to handle ozone without corroding or breaking down
- Connections: 1/4 inch (DN8) male thread in/out, with a 4mm barb for ozone gas
Why PVDF matters for ozone work
Ozone is tough on materials. It eats away at metal and makes regular plastic brittle. PVDF doesn’t react with ozone, chlorine, acids, or bases. That means this injector will keep working reliably for 5–8 years, way longer than cheaper alternatives. No rust, no cracks, no unexpected failures mid-cycle. If you need a larger unit for higher flow rates, check out our Venturi Injectors for Ozone series — they use the same durable PVDF build but scaled for bigger jobs.
Where this small-flow injector shines
This isn’t for big industrial plants — it’s built for the small, specific jobs:
- Under-sink water filters: Fits in kitchen cabinets to add ozone to drinking water, killing bacteria without a chemical taste
- Countertop ozone machines: Compact enough to fit inside tabletop units for drinking water or cleaning solutions
- Small bottling lines: Local water brands or micro-breweries needing gentle sanitization for small runs
- Aquariums and reef tanks: Drops ozone into sump areas to keep water clear without taking up space
- Lab water systems: Doses ozone into ultra-pure water setups to sanitize the system
How it works (simple, no moving parts)
- Water flows in under pressure
- It hits the narrow throat, speeding up and dropping pressure
- The pressure drop creates a vacuum
- The vacuum pulls ozone gas through the 4mm barb
- Gas and water mix in the expansion zone
- Ozone-infused water flows out the other end
That’s it. No motors, no valves, nothing to wear out. Just the Venturi principle, working quietly and reliably. For full system setup tips, you can refer to our Ozone System Parts guide.
Key specs you need to know
| Spec | Details |
|---|---|
| Water flow | 0.05–0.25 T/h |
| Ozone suction | 0.5–1.5 m³/h |
| Liquid draw | 25–60 L/h |
| Connections | 1/4 inch (DN8) male thread, 4mm barb |
| Pressure range | 0.1–1 MPa (liquid), 0.1–0.2 MPa (gas) |
| Material | PVDF body, PTFE seals |
| Length | 57mm |
Quick fixes for common issues
- Low ozone suction: Water pressure too low? Turn up the pump.
- No suction at all: The throat might be clogged. Soak in mild acid (citric or vinegar) to dissolve scale.
- Water flowing backward: You installed it backward. Check the arrow on the body for direction.
- Leaks at connections: Fittings might be loose. Tighten them or replace the PTFE seals.
Quick Q&A
Q: What does “2 point injector” mean?
A: It refers to the 1/4 inch (DN8) connection size, made for small pipes and low-flow systems.
Q: Can I use this with oxygen or air instead of ozone?
A: Yes, it works with any gas. Just double-check material compatibility with your gas first.
Q: How hot can the water be?
A: PVDF is rated up to 120°C, but most ozone applications run between 10–40°C.
Q: Do you help with system design?
A: Absolutely. We’ve been in this business since 2011, with customers in 130+ countries. We’ll help you size this and other parts to fit your setup. For complete water treatment solutions, explore our Venturi Ozone Systems range.
At the end of the day, this is a simple, tough little injector built to handle small ozone jobs. No frills, no fancy parts — just consistent, reliable ozone mixing.
