When access to the inside of your tank is difficult, this vibrator can be installed and removed from outside of the bin for easier cleaning than bolt-on aerating vibrators. Also known as a fluidization nozzle, it creates flow in your bin or hopper by combining vibration and aeration to dislodge compacted material. It is often used with dry, powdery materials such as cement, starch, and clay. Use continuous air to aerate your bin. They can be used in a system with a timer and solenoid valve to create a vibrating or pulsing action. To install, insert the bushing through a hole in the bin wall until it's flush with the inside of the wall. Then weld it in place, thread the nozzle into the bushing and connect your air supply. For large containers, mount several aerators in rows set 6" to 18" apart.
