Cone with end tapered at 45° angle (ATEX/ESD)
Product description
Cone with end tapered at 45° angle – Black Line is a conical nozzle for industrial vacuum cleaning systems, manufactured from oil-resistant NBR rubber. The nozzle is designed for efficient collection of both fine and coarse materials and is particularly suitable for industrial environments where mechanical durability and controlled dissipation of electrostatic charges are required.
The nozzle has a total length of 195 mm.
What can the product be used for
- Vacuum cleaning of dust, granulates and process residues
- Collection of small, medium and larger particles
- Vacuum cleaning in industrial environments requiring ESD control
Industries using the product
- General industry
- Process industry
- ATEX-related production environments
Technical note
The Black Line variant is manufactured using NBR rubber compound MM019NN. The electrical properties of the compound are documented through volume resistivity measurements performed by an accredited laboratory (CERISIE) in accordance with ISO 1853:2011.
The measured volume resistivity of the raw material is approximately 1.1 Ω·m, and the electrical resistance is stated within the range of 5–50 kΩ. The reported measurement results refer exclusively to the tested sample.
The manufacturer’s documentation states that identical values cannot necessarily be reproduced under different test conditions, in other laboratories or on finished products.
Progetto Gomma S.r.l. does not issue declarations of conformity with the ATEX Directive (94/9/EC / 2014/34/EU) for accessories for industrial vacuum cleaning systems. Accessories are not ATEX-certified as standalone components.
It is the responsibility of the equipment manufacturer to assess suitability, ensure correct equipotential bonding and perform the overall ATEX assessment of the finished equipment in which this product is installed.

FAQ
What does it mean that the Cone with end tapered at 45° angle – Black Line is antistatic?
Being antistatic means that the NBR rubber compound MM019NN used in the product has documented electrical properties that allow controlled dissipation of electrostatic charges during vacuum cleaning.
Is the Cone with end tapered at 45° angle – Black Line ATEX certified?
No. Accessories such as nozzles are not ATEX-certified as standalone products. Compliance with the ATEX Directive must be assessed as part of the complete equipment.
Which materials are used in the product?
The product is manufactured from oil-resistant NBR rubber compound MM019NN. The manufacturer’s documentation does not specify further material details.
Can the product be used in ATEX zones?
The product may be used as a component in equipment intended for ATEX-classified zones, but only as part of an overall assessment of the complete system.
