Filtration method: Inertial separation

Contaminant separation takes place through particle and air stream inertia energy; inertial separation generally describes a head on impact due to a lack of inertial change.  The air being filtered is forced through and around the fibres in the filter pleat pack, if the contaminant particles are carrying too little or too much inertia to make an effective change of direction around a fibre they will hit the fibre and stop. Surface friction and areas of static low pressure air around the particle base prevent the contaminant from moving back into the air stream.

Inertial separation is prevalent in all filter styles and will affect all contaminant particle sizes; it’s effectiveness can be influenced by the saturation of other particles in the air stream, particles can be both dislodged but also trap other particles.
