Brewstar 2500 Assembly

Heat, aeration and agitation are all necessary for efficient multiplication. The Brewstar 2500 Assembly™ delivers all three in an inexpensive, portable unit.

The Brewstar 2500 Assembly™ is an exciting, versatile and multi-faceted new tool for the microbe brewer. In addition to microbe multiplication, the unit can also be used for solubilising granular fertilisers such as urea or humates for DIY recipes. The Brewstar 2500 Assembly™ includes the venturis and all necessary plumbing equipment, but the pump itself is sold separately.


  • The kit can be attached to any appropriate pump (suitable supplier listed on reverse).
  • This unit can then be used for brewing volumes from min 400 litres to 2500 litres max.
  • The Brewstar 2500 Assembly™ delivers dissolved oxygen more efficiently than most other brewing apparatus on the market and far more cost-effectively.
  • Agitation is supplied via a centrifugal pump (sold separately) capable of pumping 300 litres per minute – it is important to provide agitation to the brewing solution to prevent “dead-spots” from occurring in the tank.
  • Heating is supplied from elements that are housed within the recommended pump and the temperature is monitored with a supplied thermometer.
  • Aeration is supplied by four venturi ports that are located at the end of the 50 mm (2”) flex coil outlet hose.
  • This unit features a bypass system that allows the user to fill spray rigs from the brewing unit without having to stop the aeration of the brew mix.
  • Materials with poor solubility like potassium sulfate and boron products can be rapidly dissolved in the heated, agitated environment of the Brewstar 2500 Assembly™.
