The RATEC KBD-100 fluidisation nozzles are silicone fluidisation nozzles with a Ø of 100 mm in the standard version, which use targeted air injection to loosen bulk material in silos and containers, preventing bridging and clumping. They are installed from the inside through a bore in the silo or container wall and are the standard solution for temperatures up to 80 °C. Like all RATEC silicone fluidisation nozzles, they are made entirely of FDA-compliant materials, making them suitable for food and pharmaceutical applications as well.

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-100 is also available in other sizes: KBD-30 and KBD-60. The function and design are the same, only the size changes. For other operating conditions, there are the KBD-100A external mounting version and KBD-100H high-temperature version.
