Explosion protection

The CE and ATEX markings on this unit ensure both a high level of safety and
protection against ignition of the collected combustible dust. However, if an
explosion occurs due to misuse, insufficient maintenance or faulty installation,
this unit is equipped with additional protection methods to avoid dangerous
pressure build-up in the filter.
E-PAK 150 DX/300 DX/500 DX is equipped with either an explosion relief
panel, see Section 4.1.1 Method 1: Explosion relief venting, or an explosion
suppression system, see Section 4.1.2 Method 2: Explosion suppression system.
The suppression system is normally only used if venting is impossible due to
the location of the filter, dangerous material properties or a resulting flame.
4.1.1

Method 1: Explosion relief venting

The harmful effects of an explosion are minimized by venting the pressure
and flame of the explosion through an explosion relief panel. In case of an
