The KBDS-25 sinter fluidisation pads from RATEC are made of highly porous stainless steel and finely distribute air into silos and containers so that the bulk material is loosened and does not form bridges. They are of one-piece design and are simply installed in a Ø 21 mm borehole. The corrosion-resistant stainless steel is solid, durable and operates silently—ideal for chemicals and pharmaceuticals 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.

Your benefits
- High air permeability: uniform, fine air distribution in the product.
- High strength: robust even with abrasive bulk materials.
- Corrosion-resistant stainless steel: durable and silent.
- Easy installation: one-piece nozzle for a Ø 21 mm borehole.
Other sizes and designs
Other designs made of sintered metal: sinter fluidisation connector with sleeve KBSS and sinter fluidisation connector with flange KSS-80. If you are looking for a flexible, self-closing solution, you will find it with the silicone aeration nozzles. You can find an overview of all aeration systems under Aeration systems.
