We have developed this apparatus to help dramatically increase the extraction of bacteria, fungi, nematodes, protozoa and micro-arthropods from compost. These extraction chambers are equally suited for making actively aerated compost tea or liquid extracts of compost.
These professional grade units fit into a tank opening from 8 to 15 inches in diameter. Our extraction chambers are driven with an optional auxiliary air pump in order to effectively extract the biology from the compost while making compost tea or liquid compost extracts. There are no moving parts or water pumps which can cause damage to the fragile micro biology.
The EX-3W/P Extraction Chamber offers a major advantage over traditional compost containment bags which do not have an internal air input. There are two air diffusers mounted at the bottom of the EX-3 W/P which adds the energy required to extract the biology from the organic matter. This extra air input also increases dissolved oxygen levels within the brewer.
These extraction chambers should be driven with an additional air pump. It is best not to divert air away from the main diffusion system of the compost tea brewer.
