Black antistatic long conical nozzle in MM019NN NBR compound for ATEX Zone 21 and Zone 22 – Ø50 mm, 300 mm long

Used together with

Long conical nozzle in antistatic MM019NN NBR compound for precise spot extraction in ATEX-classified Zone 21 and Zone 22. The elongated conical shape with narrow tip concentrates airflow and delivers powerful suction over an extended reach for collection of fine dust and powder — cereals, starches, sugars, light metals, coal and wood dust — in explosive industrial environments.

Applications

The long conical nozzle is designed for spot extraction of fine dust and powder in ATEX-classified environments, where the extended length allows the operator to maintain a safe distance from hazardous material. Typical industries and materials:

  • Food production — cereals, starches, sugars, flour products
  • Woodworking — sawdust and wood dust
  • Metal processing — aluminium and magnesium dust
  • Chemical industry — explosive powder and granulate
  • Coal processing — coal and coke dust
Important notice: 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 CERISIE laboratory in accordance with ISO 1853:2011. The ATEX Directive certifies the complete installation — the nozzle's role is to provide documented antistatic properties that the system manufacturer incorporates into the overall ATEX certification. It is the installer's and user's responsibility to verify suitability for the specific ATEX-classified environment and dust class.

Frequently asked questions

The elongated conical shape — 300 mm for Ø50 and 255 mm for Ø38/Ø40 — provides extended reach, enabling the operator to maintain a safe distance from potentially explosive material. Both variants share the same antistatic properties in MM019NN compound with documented volume resistivity of 1.1 Ω·m (CERISIE, ISO 1853:2011).
The nozzle is not ATEX-certified as a standalone product. It is manufactured in a compound with documented antistatic properties, certified by CERISIE laboratory in accordance with ISO 1853:2011. The ATEX Directive certifies the complete installation — the nozzle's documented properties form part of the overall assessment. 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 and Ø50 mm. The diameter must match the pipe system on your vacuum unit. Contact us if you are unsure about the correct dimension.
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.
The greater length gives the operator additional distance from the dust source, which can reduce exposure in explosion-classified zones. Combined with the documented antistatic properties of MM019NN compound, this makes the long nozzle ideal for applications where both reach and equipotential bonding are critical parameters.
Yes — the long conical nozzle is also available in transparent silicone compliant with FDA 21 CFR 177.2600 for food and pharmaceutical environments. See the Food & Pharma product page for details.
