Cyclone for Brewers and Blenders NEW.jpg


The Bubbers are the basic Brewers.  Simply in design and function and excellent performance. If your volume requirements fit, this is the system for you. 


The Systems are available in size: 13 Gallon 

All Systems are Powered by AIR:      110 VAC Standard - 12 VDC Optional


The Air Pump agitates the water to extract the nutrients and increase the oxygen content of the water over 400%. Typically to 8 ppm +.


Bubblers have no moving parts, are easy to clean and are manufactured from food grade non-corrosive materials.


Bubblers Comply to the following Regulations:

NSF/ANSI Standard 61

FDA 21 CFR 177.1520

Cyclones are perfect solution for the Retail Hydroponic and Nursery Store as well as the Serious Gardeners who demand the best.


Cyclone’s are designed to excel not only as a COMPOST TEA BREWER But are an excellent NUTRIENT BLENDER.


How does the Cyclone work?

Air is injected into the unit below the Tank into the 2″ diameter hydraulic unit. At that point the air bonds with and lifts the water vertically via the 2″ hose.

The water re-enters the Tank at the upper edge and begins it’s journey to the bottom of the Tank in a whirlpool or cyclone motion. 

The water is moving at a rate of about 7 gallons minute. The 30 Gallon Cyclone will completely recirculate the water in less than 5 minutes. 

At the same time, the brewing is occurring the Air Pump System is injecting over 5.29 CFM / 2375 Gallons of Air Per Hour  (GPH) in the water. This injection raises the Oxygen Content of the Water over 400%. We typically see Oxygen Contents that exceed 8.3 to 11.5 parts per million (PPM). Microorganism likes to see about 6.25 PPM to start the reproductive cycle and need about 4.25 PPM to stay alive.

Because of the Round Cone Bottom Tank, the gentle movement of the water is beneficial to the microorganisms and especially to the fungal spores.

Volcano's are designed to operate at peak efficiently with minimum maintenance and minimum operating cost.

30 - 60 - 75 - 145 - 250 -500 - 850 -1010- 1500 - 2610  Gallon Systems.

All Volcanoes utilize Cone Bottom Tanks for superior  performance.


Volcanos have been extensively tested for Oxygen Levels, dissolved Solid Extrations and we contantly do Microscopic inspection of the final Tea Product .

We typical see the Oxygen Content of the Water increase to about 11.25 PPM within a 15 - 20 mins.

We have found no other methodolgy or technology that out performs the Volcano.


If you are looking for a brewer that is designed for long term commecial uses and demand  consistant top level performance the VOLCANO Series is the one for you.

Volcanos ship via Truck to Commerical Site or Local Truck Terminal.

Call for additional shipping fees imposed by Truck Companies  to Residential Sites or Farms or International

THE VOLCANO and THE CYCLONE  utilize "Cone Bottom" Tanks designs.

The design allows the Air System to keep the Fertilizers/Nutrients in constant motion.

The motion is a Circular Pattern in a Bottom to Top Re-circulation motion.
