The KBSS-80 sinter ventilation nozzles from RATEC are made of highly porous stainless steel and introduce finely distributed air into silos and containers so that the bulk material is loosened and does not form bridges. They have a size of Ø 3″, 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—ideal for chemicals and pharma as well as for abrasive bulk materials.

How sinter ventilation works
The air flows through the porous sintered stainless-steel body and exits finely distributed into the bulk material via its surface. The product is loosened, i.e. fluidized; lumps and bridges break up and the bulk material flows evenly again.

Other sizes and designs
The KBSS-80 is also available in the same design in sizes KBSS-25 and KBSS-50. Other sintered-metal designs: KBDS-25 sinter ventilation nozzle and KSS-80 sinter ventilation nozzle with flange. If you are looking for a flexible, self-closing solution, you will find it with the silicone ventilation nozzles. You can find an overview of all ventilation systems under Ventilation systems.
