The ceiling filter media is constructed from selected high-performance, non-breakable fibres in a progressively density multi-layering technique to ensure high-depth loading with optimally low pressure drop performance.
The media is thermally bonded and impregnated in full-depth with a special adhesive coating to prevent any release of fibres and migration of paint-damaging particles larger than 5 microns due to the vibration in the system, even under varying temperature conditions.
