The KBSS-25 sinter ventilation nozzles from RATEC are made of highly porous stainless steel and introduce finely distributed air into silos and containers to loosen the bulk material and prevent bridging. They have a size of Ø 1″, are simply screwed in via a threaded socket, and are available in three identical sizes. The corrosion-resistant stainless steel is strong, durable, and operates silently, making it ideal for the chemical and pharmaceutical industries as well as for abrasive bulk materials.

How sinter ventilation works
The air flows through the porous sintered stainless steel body and exits into the bulk material finely distributed over its surface. The product is loosened, or fluidized; clumps and bridges dissolve, and the bulk material flows evenly out of the cone again.
