Feili 2 Point PVDF Venturi Injector

This is our smallest injector. 2 point. 57mm long. Handles 0.05 to 0.25 tons of water per hour.

It works the same way as our big ones. Water goes through a narrow throat. Speed picks up. Creates a vacuum. Vacuum pulls ozone into the water. No moving parts. Nothing to break.

PVDF plastic. Ozone eats through metal and regular plastic over time. PVDF does not. That is why we use it.

This little guy is one of our Venturi Injectors. Fits in tight spots. Works with small ozone generators.

The numbers you need

Where people put this thing

Food plants. Need clean water for washing stuff. No chemicals allowed. This injector puts ozone into the water line. Kills bacteria. Leaves no residue. It is a small Ozone Venturi Mixers setup that fits right in.

Cooling towers. Small ones. They grow bacteria. Legionella. This injector doses ozone into the cooling water. Stops the growth. No handling of dangerous chemicals. PVDF handles the warm water fine.

Bottled water lines. Small bottlers. Need to sanitize bottles and caps. Ozone works. This injector puts it into the water. Simple. Reliable.

Pharmaceutical rinse. Drug makers need sterile water for washing equipment. No residue allowed. Ozone breaks down to oxygen. This injector delivers.

Rural water systems. Small towns. Well water. Need disinfection without chlorine taste. This Venturi Injectors for Ozone setup does the job. No complex equipment needed.

How to put it in

Step one. Mount it. Horizontal or vertical. Follow the arrow.

Step two. Hook up water to the 1/4 inch inlet.

Step three. Connect your ozone generator to the 4mm barb. Put a check valve on that line. Otherwise water backs up and kills your generator.

Step four. Run the outlet to your tank or pipe.

Step five. Check pressure. For liquid mixing, 0.3 to 0.6 MPa works well. For gas mixing, 0.12 to 0.18 MPa.

What to expect

Taking care of it

These Ozone System Parts do not need much.

Once a month. Look at the suction port. See any junk? Clean it out.

Every three months. Check the vacuum with a gauge. Still pulling hard? Good.

Every six months. If flow feels weak, soak the whole thing in mild acid. Citric acid works. Vinegar works. Rinse with water. Do not scrape inside.

Once a year. Still working fine? Keep using it. Performance dropped? Replace it.

Problems and fixes

Low ozone suction. Water pressure too low. Turn up the pump. Or throat is dirty. Soak it.

No suction at all. Throat is completely blocked. Or injector is backward. Check the arrow.

Water going back to ozone generator. No check valve. Or check valve failed. Put one in. Replace it if bad.

Pressure drop too high. You are pushing too much water through a small injector. Get a bigger size.

Short Q&A

Q: Why PVDF instead of PVC or metal?
A: PVC gets brittle under ozone. Metal corrodes. PVDF does neither. That is why it is the standard for Venturi Injectors for Ozone.

Q: Can I use this for oxygen or air?
A: Yes. Works with any gas. Ozone. Oxygen. Air. Whatever.

Q: What if water flows backward?
A: Bad. Ruins the precision throat. That is why you need a check valve on the suction line.

Q: How does this compare to bigger injectors?
A: This is for small flows. 0.05 to 0.25 tons per hour. Need more? We have 4 inch, 1 inch, 1.5 inch, 2 inch. Ask us.

Q: Can I use this with saltwater?
A: Yes. PVDF handles salt. No problem.

Q: How much pressure do I lose across this thing?
A: About 0.05 to 0.15 MPa at normal flow. Account for it when you pick your pump.

Q: Do you help with system design?
A: Yes. 14 years doing this. Customers in 130+ countries. We help size everything. Just ask.
