595 x 595 x 350mm Deep Bed Filters Framed

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