This specialized conical nozzle retrofits the Avast Marine Fluidized Media Reactors into a biopellet-specific mixing chamber. It allows complete fluidization of biopellets with no channeling or clumping. Installation into existing media reactors is simple: cut the center pipe about 2.5" (63mm) from the bottom, then press-fit the nozzle onto the pipe.
The conical shape allows pellets to flow downwards evenly without getting stuck against the center tube. The screen at the wide end has holes big enough to resist clogging far better than a sponge or nylon mesh, but small enough to prevent pellets from back-siphoning into the pump when power is off.
