U025 and U060 Aeration Nozzles can be easily fitted on bins or silos from outside which makes them particularly suitable for retrofitting or in cases where the inside of a bin cannot be accessed. For sizing, layout and number of nozzles refer to the relevant data sheet.

The plastic insert with the sintered metal nozzle has to be screwed into the steel nipple which has been previously welded on the outside of the bin or silo. Then the connection with the compressed air line has to be carried out.

U025 and U060 Aeration Nozzles are used with fine powdery materials at a working pressure of 3 PSI, while U060 Aeration Nozzles work with a pressure of 14 PSI. Decades of experience with U025 and U060 have shown that virtually all materials can be successfully fluidized at intermittent operation according to Pulse-Jet or Felder System.
