The KBD-60H fluidisation pads from RATEC are Ø 60 mm silicone fluidisation pads in a high-temperature version, which specifically loosen bulk material in silos and containers with air, thus preventing bridging and clumping. They withstand temperatures up to 200°C and can be installed from the inside or, using an external mounting kit, from the outside. 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.
- 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-60H is also available in other sizes: KBD-30H and KBD-100H. The function and design are the same; only the size changes. For other operating conditions, there is the standard version KBD-60 and external mounting KBD-60A. An overview of the sintered metal fluidisation pads can be found under Aeration systems.
