The RATEC KBD-60A fluidisation pads are silicone fluidisation pads with Ø 60 mm for external mounting that loosen bulk material in silos and containers with targeted air flow, preventing bridging and clumping. Thanks to the external mounting bolt, they are mounted on the outside of the silo or container and are also available as a high-temperature version up to 200 °C on request. Like all RATEC silicone fluidisation pads, 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.
- External mounting: via the external mounting bolt, optionally also as a high-temperature version.
- Chemical-resistant: robust even with demanding products.
- Uniform material flow: no bridging, no blockages.
Other sizes and versions
The KBD-60A is also available in another size: KBD-100A. Function and design are the same, only the size changes. For other operating conditions, there is the standard version KBD-60 and the high-temperature version KBD-60H. For an overview of the sintered metal fluidisation pads, see Aeration Systems.
