Tri-Dim’s Tri-Cube lets Columbia Filters offer all the benefits of Tri-Dek® panels and links with the added benefit of extended surface area. The versatile Tri-Cube employs a unique combination of 2, 3, or 4-ply configurations, and are now available from Columbia Filters in efficiencies up to MERV 13. The Reverse Flow Cube (Tri-Cube RF an RFX filters) were designed to solve a real-world problem where there was no room downstream of the filter bank, and the application demanded an extended surface filter. The Tri-Cube filters are available with a metal header, multiple pockets, UL Class 1 and many other options.
