Product Description

Spas stay clean and safe with a Mazzei Injector and a DEL Spa Ozonator.  And using a Mazzei Injector eliminates harmful ozone off-gas known to decrease the life of spa covers and pillows.

Mazzei Injector #684K:

  • Red, Kynar
  • Ozone- and weather-resistant for longer lifespan
  • 3/4" Hose Barbs for easy installation into flexible plumbing
  • Without built-in Check Valve
  • Without built-in O'ring (use Teflon tape)
  • DEL Ozone Part Number is 7-0356
  • Not the most common injector used in hot tubs due to restriction, it works great on hot tubs with lower flow rates*

How does ozone get INTO the spa water?  Most spas use a Mazzei Injector which is connected to the spa equipment.  When the ozone generator is operating, ozone is automatically introduced into the water where it can kill viruses, bacteria, yeast, mold, mildew, and spores plus break down oils and help remove metals and minerals.

Watch this great DEL Ozone video to see a Mazzei Injector working with DEL's MCD-50 and Ozone Supply Check Valve (7-1140-01).

Using an integrated system with intelligent design, the MAZZEI system components work together to optimize performance by raising the ozone concentration while lowering the gas-to-liquid ratio.

Key Features of MAZZEI Technology:

  • Ozone Concentration – Concentration and solubility are directly proportional so that higher ozone concentrations promote the transfer of more ozone into solution.
  • Gas-to-Liquid Ratio – A lower gas to liquid ratio (Vg/Vl) allows for greater ozone mass transfer efficiency.
  • Water Pressure – Higher pressure yields increases in ozone solubility.
  • Water Temperature – Higher temperature reduces solubility, but increases the chemical reaction rate.
  • Mixing – Intense, forceful mixing allows for the rapid renewal of the gas-liquid interface, increasing the mass transfer rate and the reaction rate.
*Hot Springs Spas is an example of a spa manufacturer which uses this injector in some (not all) of their models.

If your spa has a different kind of injector, www.LoveYourHotTub.com recommends upgrading to Mazzei Injector.

Some spas do not have an ozone injector; ozone is injected through a jet.  Bubbles should be fine and tiny.  If they are not, your system may need fine-tuning.  

Here are signs ozone is not getting into the water properly:  

1) Ozone odor is strong when you lift the cover
2) Spa water looks, smells and feels bad
3) Ozone bubbles are too big.  Bubbles should be like champagne bubbles

If you feel your spa's ozone system could use improving by installing a Mazzei Injector, let us guide you.  Email us at: help@loveyourhottub.com.  And, if your spa ozone goes through the spa jets and installing an injector is not an option, you may be able to install a Mazzei LGM.
