ATEX Air Filters from AAF

For all Explosion Hazard Zones


AAF offers a special range of air filters designed for use in potentially explosive environments. All product versions are electrostatically dissipative and in full compliance with ATEX Directive 2014/34/EU (old designation 94/9/EC) for use in hazardous areas. AAF’s dissipative air filters can be used safely over the entire range of explosive groups and in all hazardous zones specified in the ATEX Directive. They are made with electrically dissipative plastic frames which are lighter in weight than conventional materials such as metals. This facilitates installation and also makes the filter fully incinerable, therefore reducing disposal costs.

All conductive and dissipative components used in ATEX zones must be reliably earthed (i.e. grounded) to permit proper electric discharge. AAF ATEX compact cassette filters incorporate recesses on the inlet and outlet sides of the filter frame which are used to mount the earthing lug on either side as desired. The earthing lug and its mounting hardware are supplied along with the filter system. ATEX filters from AAF are made with high quality glass fibre media providing outstanding filtration efficiency. The filter material‘s superb quality and innovative minipleat configuration ensure optimum utilization of filter surface area along with heavy-duty strength. Standard versions with up to 40m² filter area as well as individualized versions with custom dimensions are available in filter classifications ranging from ISO filter classes according to ISO 16890 (formerly EN 779) to HEPA filter classes according EN 1822.

Le nom ATEX vient du français : "ATmosphères EXplosibles". Le code réglementaire applicable en Europe est la directive 2014/34/UE (ancienne désignation 94/9/CE). Cette directive spécifie que les appareils et les systèmes de protection utilisés dans des atmosphères potentiellement explosives doivent être capables de dissiper les charges électrostatiques. Les filtres à air utilisés dans ces zones dangereuses doivent également répondre à cette exigence.

Définition
20/0 L'atmosphère explosive est présente en permanence, ou pendant de longues périodes ou fréquemment.
21/1 Une atmosphère explosive est susceptible de se produire occasionnellement en fonctionnement normal.
22/2 Une atmosphère explosive n'est pas susceptible de se produire en fonctionnement normal mais, si elle se produit, elle ne persistera que pendant une courte période.
