The Coarse 75% pleated panel filter is the workhorse of commercial and industrial ventilation — a dependable pre-filter that protects downstream coils, fans and higher-grade filters from the bulk of airborne dust and debris. Under the previous EN 779 standard, this grade was known as G4, and it remains the go-to choice for general-purpose air handling units, ventilation systems and pre-filtration duties.
Its pleated construction increases the surface area of the media, giving you a longer service life and lower running costs than a flat-panel equivalent, without restricting airflow. Supplied with a standard 47mm depth to suit common AHU and ventilation housings.
Ideal for: AHU pre-filtration, general ventilation, protecting secondary filters and heat-exchange coils.
