Big Cone – Black Line (ATEX/ESD)
Product description
Big Cone – 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 very fine dust and powders in industrial environments where controlled dissipation of electrostatic charges is required.
The conical shape combined with a sectioned geometry provides stable material flow and precise handling during vacuum cleaning, even when dealing with very fine particles.
The nozzle is supplied with an overall length of approximately 255–300 mm depending on the diameter.
What can the product be used for
- Vacuum cleaning of very fine dust and powders
- Handling of lightweight and airborne materials
- Industrial cleaning operations with ESD control requirements
Industries using the product
- General industry
- Process industry
- ATEX-related production environments
Technical note
The Black Line variant is manufactured using oil-resistant 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 Big Cone – 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. These properties are documented through volume resistivity measurements in accordance with ISO 1853:2011.
Is Big Cone – Black Line ATEX certified?
No. Accessories such as vacuum nozzles are not ATEX-certified as standalone products. The manufacturer does not issue ATEX declarations for this product. 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.
How are the electrical properties documented?
The electrical properties are documented through laboratory measurements performed by CERISIE in accordance with ISO 1853:2011 on raw material supplied by the manufacturer.
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. It is the responsibility of the equipment manufacturer to ensure correct installation, equipotential bonding and complete ATEX evaluation.
