Suitable for All Explosion Hazard Zones!
EMW® now offers electrically dissipative IECEx-certified air filters for use in potentially explosive environments.
All IECEx air filters offered by EMW® provide directive-compliant safety over the entire range of hazardous zones.
So why are we talking about IECEx air filters? The ATEX directive that once also applied to air filters still exists. However, it is no longer aimed at air filters! In theory, the filters no longer have to meet any special requirements with regard to explosion protection according to the ATEX directive. In order to not only offer safety in potentially explosive areas, but also to be able to prove it, EMW's former ATEX filters are now IECEx-certified.
EMW®'s IECEx-certified air filters (formerly ATEX-certified Air Filters) are suitable for use in potentially explosive environments. Designed for heavy-duty offshore applications, the new IECEx panel filter provides reliable operation under even the toughest conditions.
Stabilizers integrated in the filter protect and maintain the pleat pattern in the media, ensuring low initial pressure drop with minimal increase in subsequent operation. The conductive synthetic media is solidly mounted around its entire perimeter in a dissipative plastic frame. A seamless cast-in-place seal holds the air filter firmly in place without leakage.
The name ATEX comes from the French: "ATmosphères EXplosibles". The applicable regulatory code in Europe is Directive 2014/34/EU (old designation 94/9/EC). This directive is made for manufacturers of ATEX product and specifies that equipment and protective systems operated in potentially explosive atmospheres must be capable of dissipating electrostatic charge. Air filters used in these hazardous areas must also meet this requirement. The guideline for operation is based on the ATEX operational policy 1999/92EG.
| Zones (Dusts / Gases) | Definition | |
|---|---|---|
| 20/0 | Explosive atmosphere is present continuously, or for long periods or frequently. | |
| 21/1 | Explosive atmosphere is likely to occur in normal operation occasionally. | |
| 22/2 | Explosive atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only. |
It should be noted that the ATEX Directive no longer applies to air filters. In theory, air filters do not have to meet any special requirements with regard to explosion protection according to the ATEX Directive. In order to still offer safety in potentially explosive areas and also to be able to prove it, EMW's former ATEX filters are now IECEx certified.
EMW®'s dissipative air filters can be used safely over the entire range of explosive groups and in all hazardous zones specified in the IECEx Standard. A wide variety of compact cassette filters, filter boxes and panel filters are available to meet users' diverse needs. 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 EX zones must be reliably earthed (i.e. grounded) to permit proper electric discharge. EMW® filter boxes and panel filters are earthed by means of integrated earthing lugs combining dependability and user-friendliness. EMW® 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.
EMW®'s IECEx filters 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 40 m² filter area as well as individualized versions with custom dimensions are available in filter classifications ranging from M6 to H14.
