The RATEC KBD-100H Fluidisation Pads are silicone fluidisation pads with Ø100mm in the high-temperature version, which use targeted airflow to loosen bulk material in silos and containers, preventing bridging and clumping. They withstand temperatures up to 200°C and can be installed from the inside or, with an external mounting kit, from the outside as well. Like all RATEC silicone fluidisation pads, they are made entirely of FDA-compliant materials, making them suitable for food and pharmaceutical applications too.

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.
- Heat-resistant up to 200 °C: for hot bulk materials and processes.
- Chemical-resistant: robust even with demanding products.
- Uniform material flow: no bridging, no blockages.
Other sizes and versions
The KBD-100H is also available in other sizes: KBD-30H and KBD-60H. The function and design are the same, only the size changes. For other operating conditions, there is the standard version KBD-100 and the external mounting version KBD-100A. For an overview of the sintered metal fluidisation pads, see Fluidisation Systems.
