Koch Service Rolls & Media Pads | Bulk Synthetic, Foam & Hogshair

Koch service rolls, media pads, and bulk synthetic media — the cut-to-fit options for AHU retrofits, custom holding-frame installations, and applications where standard nominal-size panels won't cover the spec. MD synthetic rolls in 1″ and 2″ depths for AHU prefiltration. Synthetic media pads cut to standard nominal sizes for Type 8 holding-frame installations. Foam media for grease and high-humidity prefiltration. Hogshair media for industrial intake and dust-collection applications. Pair with Koch permanent metal frames or third-party Type 8 holding frames for facility-grade installations.
