595 x 595 x 350mm F4 Deep Bed Filters – Incl. Frame

A 595 x 595 x 350mm F4-rated deep bed filter supplied complete with a galvanised steel frame for air handling units requiring high dust-holding capacity and extended service life. The deep bed construction provides a substantially larger media volume than standard panel filters, making it suitable for commercial HVAC systems with continuous or heavy-duty operation. The included frame ensures a rigid, secure fit and eliminates filter bypass.
