Applications

  • Collection of food waste, crumbs, powder and granules in production lines
  • Extraction of chemical dust and particle residues in pharma environments
  • Cleaning of production equipment and bench surfaces in cleanroom-adjacent zones
  • Flour and confectionery industries, dairy, cosmetics and chemical manufacturing
Compliance information: The silicone compound Wacker Chemie R 4001 80 complies with FDA 21 CFR 177.2600 (USA) and BfR Recommendation XV “Silicone” (Germany) for the polymers and ingredients in the material. It is the manufacturer’s responsibility to ensure that the moulding and finishing process meets these standards, and the end user’s responsibility to verify material compatibility with the specific intended application.

Colour coding and hygiene

The Colour Line concept enables systematic colour coding of vacuum accessories in food and pharma environments, where visual segregation of equipment forms part of internal hygiene procedures and GMP requirements. Colour coding reduces the risk of cross-contamination by assigning specific colours to separate process zones, allergen statuses or product types:

  • Blue — allergen-free zones or dry products
  • Red — meat processing or controlled process zones
  • Green / yellow / white — additional colours adapted to internal colour coding systems
Please note: The standard Colour Line is manufactured in oil-resistant NBR rubber without FDA compliance. FDA-compatible versions carry the suffix F and must be specified at the time of ordering. It is the end user’s responsibility to verify the material’s suitability for the specific application.

Frequently asked questions

The silicone version (White Line) is compliant with FDA 21 CFR 177.2600 and BfR Recommendation XV in its standard form, withstands −60°C to +200°C and can be autoclaved. Colour Line is manufactured in oil-resistant NBR rubber and is available in an FDA-compatible (F) version on request, with an operating range of −20°C to +120°C. Colour Line is primarily intended for colour-coded hygiene management systems.
Yes. The silicone material Wacker Chemie R 4001 80 has an operating temperature range of −60°C to +200°C, making autoclaving possible as part of a hygiene routine. It is the user’s responsibility to verify that the rest of the tube system and accessories are also rated for the autoclaving temperature.
FDA 21 CFR 177.2600 is the US Food and Drug Administration’s regulation for rubber materials approved for repeated contact with food. BfR Recommendation XV is the equivalent German requirement for silicone materials in food contact. For the silicone version, compliance is documented for the compound Wacker Chemie R 4001 80. The end user is responsible for verifying suitability for the specific intended use.
The characteristic teeth distribute the airflow evenly across the opening width and prevent the nozzle from adhering to the surface. This provides even collection of crumbs, granules and fine powder from both hard production surfaces and flexible surfaces.
The part number is built as PV + diameter + colour letter + F. Example: Ø38 mm in green FDA version = PV238VF. Contact us with the required diameter, colour and quantity.
Yes — RAKE is also available in antistatic MM019NN NBR compound for use in ATEX Zone 21 and Zone 22, with documented volume resistivity of 1.1 Ω·m (CERISIE, ISO 1853:2011). See the ATEX product page for details.
