Conical nozzle in antistatic MM019NN NBR compound for precise point extraction in ATEX-classified Zone 21 and Zone 22. The conical shape with an angled opening concentrates the airflow and enables effective collection of fine dust and powder — grain, starch, sugar, light metals, coal and wood dust — in explosive industrial environments.

Applications
The conical nozzle is designed for point extraction of fine dust and powder in ATEX-classified environments. Typical industries and materials:
- Food production — grain, starch, sugar, flour products
- Woodworking — sawdust and wood dust
- Metal processing — aluminium and magnesium dust
- Chemical industry — explosive powders and granules
- Coal processing — coal and coke dust
Important information: This nozzle is not ATEX-certified as a product. It is manufactured in MM019NN antistatic NBR compound with documented volume resistivity of 1.1 Ω·m, certified by the CERISIE laboratory in accordance with ISO 1853:2011. It is the installer's and user's responsibility to verify suitability for the specific ATEX-classified environment and dust class.
Frequently asked questions
It is manufactured in MM019NN antistatic NBR compound with certified volume resistivity of 1.1 Ω·m (CERISIE, ISO 1853:2011), which ensures documented equipotential bonding. A standard nozzle does not have these documented antistatic properties and is not suitable for ATEX zones.
The nozzle is not ATEX-certified as a product. It is manufactured in a compound with documented antistatic properties, certified by the CERISIE laboratory in accordance with ISO 1853:2011. It is the installer's and user's responsibility to verify suitability for the specific ATEX-classified environment and zone.
The nozzle is available in Ø38, Ø40, Ø44, Ø50 and Ø70 mm. The diameter must match the tube system on your vacuum unit. Contact us if you are unsure of the correct size.
The documented electrical resistance of 5–50 kΩ and volume resistivity of 1.1 Ω·m make the nozzle suitable for use in environments requiring equipotential bonding, including Zone 21 and Zone 22. It is always the user's responsibility to verify suitability for the specific zone and installation.
Yes — the conical nozzle is also available in transparent silicone with FDA 21 CFR 177.2600 compliance for food and pharma environments, as well as in colour-coded FDA NBR versions for colour-coded hygiene systems. See the food variant, or contact us for further information.
