An ATEX Filter is a device that separates two or more media and complies with an explosion standard. The ATEX directive consists of two European Union (EU) directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere. ATEX derives its name from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosives.

ATEX Directive

Statistics show that filters are involved in the second highest percentage of dust explosions that occur in industrial applications including pharmaceutical, chemicals, metal, food, plastics, coal and wood. In July 2003, the new ATEX Directive 94/9/EC (ATEX 95) was implemented Europe-wide to eliminate the possibility of explosions related to equipment used in potentially explosive gaseous or dusty environments.


Filter Housing

Filter housing parameters constructed of conductive materials- Grounding terminals on housing Conductive o-rings and gaskets


Testing and Documentation

Each filter assembly and filter element is individually tested for conductivity

  • A point to point resistance test is performed
  • Filter housings are approved at 1000 ohms or less
  • In process inspections and a final inspection is performed
  • Each filter is assigned a serial number for easy traceability documentation is recorded and is available upon request.
