The Coarse 85% pleated panel filter is the highest-arrestance option in the coarse range, capturing the greatest proportion of larger airborne particles before they reach downstream equipment. It corresponds to the upper end of the old EN 779 G4 classification (bordering M5), making it a solid choice where you want maximum coarse-dust capture at the pre-filtration stage.
With its high-surface-area pleated media, it delivers a long service life and reliable protection for coils, fans and secondary filters. Supplied with a standard 47mm depth to suit common AHU and ventilation housings.
Ideal for: Demanding pre-filtration duties, protecting high-grade final filters, dustier commercial and industrial environments.
