The KBD-30 fluidisation pads from RATEC are silicone aeration nozzles with a Ø 30 mm standard design that specifically loosen bulk material in silos and bins with air, thereby preventing bridging and clumping. They are installed from the inside via a hole in the silo or bin wall and are the standard solution for temperatures up to 80°C. Like all RATEC silicone fluidisation pads, they consist entirely of FDA-compliant materials and are therefore also suitable for food and pharmaceuticals.

How the fluidisation pad works
The round pad body has a flexible silicone sleeve. When air pressure is applied, the sleeve opens and the air escapes evenly into the bulk material. The product is loosened, i.e. fluidised, and flows evenly out of the cone again. When the air pressure is removed, the sleeve closes automatically so that no bulk material enters the pad.

Your benefits
- Self-closing: no product in the pad.
- FDA-compliant: silicone and stainless steel, suitable for food and pharmaceuticals.
- Easy installation: from the inside via a borehole.
- Chemical-resistant: robust even with demanding products.
- Uniform material flow: no bridging, no blockages.
Other sizes and versions
The KBD-30 is also available in other sizes: KBD-60 and KBD-100. Function and design are the same, only the size changes. For other operating conditions, there is the external mounting KBD-100A and the high-temperature version KBD-30H. You can find an overview of the sintered metal fluidisation pads under Aeration systems.
