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. | |||
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. | |||
Solberg became one of the first to be certified to service those industries in need of compliance with this directive. | |||
Under the ATEX directive, Solberg’s certification includes the following: to manufacture and supply any type of inlet filter silencers, inlet filters, inlet vacuum filters, integrated liquid separators/vacuum filters and air/oil separation filters. Solberg was registered by the TUV Rheinland Group under Ref-N 968/Ex-Ab 557/04 as of 29 November 2004. | |||
==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. | |||
==Filter Element== | |||
There are many aspects involved in providing an ATEX certified filter element. Much of a filter element’s components are made from naturally non-conductive material . Solberg has developed materials and design parameters that enables the filter element to be certified. | |||
-Each filter element is individually tested for conductivity | |||
-Filter media tested under EN 13463 and EN 1127 standards. | |||
-Custom conductive gaskets and adhesive | |||
-Stainless steel endcaps, wirescreen and expanded metal support | |||
-Multiple independent means of protection integrated within filter element design | |||
-Currently approved media types for inlet filter silencers and inlet vacuum filters | |||
-Polyester: 99+% efficient to 5 microns | |||
-Paper: 99+% efficient to 2 microns | |||
-“Z” Series, Polyester: 99.9% efficient to 1 micron | |||
-PTFE Special: 99.97% efficient with non-clinging characteristics | |||
