Material Chemical Resistance

Material recommended operating conditions :

PCTG  is best for environments up to  75°C. ( excellent chemical resistance to ozone,chlorine, saltwater, hydrocarbons, oil, fuel and gas. This makes it an excellent choice for applications where exposure to strong ozone ,mild acids, mild bases, solvents, and other hydrocarbon-based substances is common.)

PVDF is best for environments up to  120°C  (exceptional chemical resistance with ozone, chlorine, Bleach, strong  acids, bases, cleaning agents, solvents, fuels and hydrocarbons)

PVDF is considered a food-grade material and has been approved for use in contact with food and beverages by the FDA in it's raw form with no additives, fillers or colors.

Maintenance

If suction performance decreases, use compressed air in the air-flow hose barb to remove and blow out any debris

Made in the USA

All of our devices are designed and made in the USA. Materials are sourced from only domestic USA manufacturers with high standards of quality and durability.

The Macromixer ( Multi Venturi Injector) is a versatile product that can be threaded onto any sump pump, fountain, or circulation water pump. Its unique design features multiple venturis, which results in a higher outflow pressure and higher flow rates than a traditional single venturi nozzle. Additionally, this product significantly increases the suction vacuum rate, making it a powerful tool for water circulation and raising dissolved oxygen.This is a MPT Venturi (Male Pipe Threads)

Optimal results will be seen when used as a jet head on the end of your piping in a tank or reservoir. If installing in-line outside of the water you will want to install it as a venturi bypass to help keep the outflow pressure higher.

If you're using as a jet head around plant roots or fish, you will want to purchase the add on threaded FPT x pvc slip adapter for a more gentle flow. This FPT adapter helps to slow down the outflow velocity of water so its safer around fish and plant roots when used as a jet head. You will also see an increase in air suction when the adapter is installed on a macromixer as a jet head on the end of the piping or pump.

1/2", 3/4" and 1" MacroMixers use a 1/4" hose barb or 1/16" NPT threads

1.5" and 2" MacroMixers use a 1/2" hose barb or 1/4" NPT threads

3" and 4" MacroMixers use a 5/8" hose barb or 1/2" NPT threaded connections

Manufactured material: Polypropylene or PVDF. Both immune to hydrolysis and water absorption.

Free from BPA, PFAS (per- and polyfluoroalkyl substances) and phthalates.

PVDF complies with food safety standards and does not contain harmful additives commonly found in other plastics. 

Both Polypropylene Carbon Fiber (PP-CF) and Polyvinylidene Fluoride (PVDF) exhibit exceptional chemical resistance, making them premier choices for harsh industrial, fluid-handling, and aggressive aquatic environments. PP-CF combines a chemically inert polypropylene matrix with carbon fiber reinforcement, rendering it virtually immune to hydrolysis, moisture absorption, ozone, chlorine, aqueous acids, and strong bases, though it can swell or degrade when exposed to certain hydrocarbons, aromatic solvents, and non-polar fuels. In contrast, PVDF is a high-performance fluoropolymer that delivers superior, broad-spectrum resistance across almost the entire chemical spectrum—including strong acids, robust bases, ozone, active chlorine, oxidizing agents, and various hydrocarbons, fuels, and oils—with near-zero permeability and exceptional long-term stability under severe environmental stress.

 

  • Higher Outflow Pressure

    Utilizes multiple venturis to ensure that there is less outflow pressure drop like a single venturi system. This feature greatly enhances the performance of various applications such as irrigation, nutrient mixing, pools, spa ozone, or filtered ponds. With the MacroMixer, you can expect efficient and reliable performance, ensuring that your systems are always functioning at their best. Additionally, our product is designed to be easy to install and maintain, making it a hassle-free solution for your needs.

  • Increased Vacuum Suction Rate

    The MacroMixer offers a significant improvement in both outflow pressure and vacuum suction rate compared to a single venturi. With a range of device sizes to choose from, you can expect an increase in suction rate anywhere from 50% to 115%. This means you can achieve higher levels of performance and efficiency in your operations, making the MacroMixer an affordable and valuable investment

  • How many venturis with each size?

    3/4" =(3) 4.5mm venturi chokes

    1" = (3) 6mm venturi chokes

    1.5" = (4) 8.5mm venturi chokes

    2" = (4) 12.5mm venturi chokes

    3" = (4) 16mm venturi chokes

    4" = (4) 18.5mm venturi chokes

    Advanced patented technology features multiple venturis, offering superior outflow pressure performance compared to traditional single venturi injectors.

  • Inject Oxygen, Ozone, Fertilizer, C02 & Atmospheric Air

    This Multi-Venturi was designed to effortlessly inject both liquid and gas for a wide range of applications. With its exceptional functionality, this device allows you to dissolve oxygen and ozone, ensuring optimal oxygenation in aquatic environments. Additionally, it enables the precise mixing of nutrients in reservoirs, promoting healthy plant growth, or conveniently injecting fertilizer or air into irrigation systems.

Areas of Oxygenation

Hydroponics & Aquaponics

Use the MacroMixer to mix nutrients, aerate worm tea, raise dissolved oxygen levels in reservoirs and water tanks. It can be used inline on piping or for best results as a jet head in the tank.

Pond Aeration

Use the MacroMixer to raise dissolved oxygen in ponds while also circulating the water column. It can help break up the thermocline layer in the pond so temperatures and oxygen can properly mix at all depths. This allows fish to access oxygenated water at deeper depths.

Irrigation

Use the MacroMixer inline on your irrigation for fertilizer injection. You can even use it to inject oxygenated water into the ground near roots for a healthier soil environment and much better root growth.

Water Treatment

Use the MacroMixer in flocculation tanks and in aeration reservoirs to raise dissolved oxygen. Use it to inject and dissolve ozone for disinfection of wastewater and drinking water.

Pool & Spa

Use the MacroMixer to inject ozone for disinfection of pool and spa water.

Fisheries & Hatchery

Use the MacroMixer to raise dissolved oxygen in tanks and reservoirs. Provide fish the higher oxygen levels they need to grow as big as possible and stay healthy.
