Applications - ATEX

RAKE ATEX nozzles are specifically used for extraction of flammable materials such as cereals, starches, sugars, light metals, coal, and wood dust in environments with explosion risk. Suitable for flour mills, woodworking, food production, and other industries with dusty processes where ATEX directives apply and efficient collection of small to medium-sized particles from floors and surfaces is required.

Installation and potential equalization

The antistatic nozzle ensures correct electrical connection between extraction system and work area. Installation must follow ATEX guidelines for potential equalization and comply with EU Directive 94/9/EC. The conductive NBR construction ensures tight connection and continuous electrical connection even with frequent use. It is the customer's responsibility to verify suitability for specific ATEX environments.
