Pleated synthetic fibre filter cell, class ISO Coarse 55% according to ISO 16890. The filter media is protected by wire mesh on both sides to ensure the consistency of the pack and the regularity of the pleat. Micro-perforated plastic mesh, due to an electrostatic effect, increases the holding capacity efficiency. The more extended filter surface area (compared to plane cells) allows more dust holding capacity (DHC) and therefore a greater service life.
Galvanised steel frame. Electro-welded galvanised steel wire protection meshes.
Filtration of airborne particles in civil and industrial air conditioning systems. It is commonly also used as pre-filtration stage for fine dust filters.
