The Nute Brewer is an air-powered pump that is built to recirculate sediment and solids that sink to the bottom of your reservoir. Unlike traditional water pumps that have internal components that are prone to jamming, the Nute Brewer is built with immobile parts that will not become jammed with sediment.
This device model was designed to fit snug in any common 5 gallon bucket. Use it to brew up a batch of your favorite compost teas without the need for filter bags. Simply plug the hose into the air pump, place the Brewer in your bucket, the plug the air pump in.
