90° bend
−20°C to +120°C
Ø32 – Ø50 mm
Curved antistatic nozzle with a 90° bend in MM019NN NBR compound for precise spot extraction from hard-to-reach places in ATEX-classified Zone 21 and Zone 22. The ergonomic bend allows access under machinery, into corners and behind equipment — while maintaining documented equipotential bonding and antistatic properties throughout.

Application areas
ALIEN ATEX is designed for the collection of fine dust and powder from hard-to-reach places in ATEX-classified environments. Typical industries and materials:
- Food production — grain, starch, sugar, flour products from corners and under equipment
- Woodworking — sawdust and wood shavings in confined constructions
- Metal processing — aluminium and magnesium dust near machinery
- Chemical industry — explosive powder and granulate at process equipment
- Coal processing — coal and coke dust from enclosed conveyors and screws
Important: The ATEX Directive certifies the complete installation, not individual components. This nozzle contributes documented antistatic properties — MM019NN compound with volume resistivity 1.1 Ω·m, certified by CERISIE laboratory per ISO 1853:2011 — which the system manufacturer incorporates into the overall ATEX certification. It is the installer's and user's responsibility to verify suitability for the specific zone and dust class.
Frequently asked questions
The 90° bend provides access to places that a straight nozzle cannot reach — under machinery, into corners, behind cabinets and close to the floor. This is critical in ATEX environments, as combustible powder collects precisely in these hard-to-reach surfaces and poses the greatest explosion risk if not collected regularly.
The nozzle is not ATEX-certified as a standalone product. The ATEX Directive certifies the complete installation. ALIEN ATEX delivers documented antistatic properties via MM019NN compound with volume resistivity 1.1 Ω·m (CERISIE, ISO 1853:2011), which the system manufacturer can incorporate into the overall ATEX certification. It is the user's responsibility to verify suitability for the specific ATEX-classified environment.
ALIEN ATEX is available in Ø32, Ø38, Ø40, Ø44 and Ø50 mm. The diameter must match the pipe system of your vacuum unit. The length is 250 mm for Ø32–Ø44 and 320 mm for Ø50. 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.
ALIEN ATEX is designed for the extraction of combustible and explosive powders and dust, including grain, starch, sugar, light metals, coal and wood dust in ATEX-classified areas. It is particularly suitable when the material is located in hard-to-reach places.
Yes — ALIEN is also available in transparent silicone with FDA 21 CFR 177.2600 compliance for food and pharmaceutical environments, and in colour-coded FDA NBR versions for colour-coded hygiene systems (Colour Line). Contact us for more information.
