Fiberglass Media“ Standard C&I Disposables are constructed with high-grade progressively dense glass fibers. The air entry side consists of open, coarse fibers, while the air exit side contains tighter fibers. This dual-density media configuration ensures proper depth loading and full utilization of the filter media. Each fiber is coated with a non-migrating adhesive to enhance filter performance.

Sturdy One-Piece Frame“ The Koch C&I Disposable utilizes a one-piece moisture-resistant craft board frame for strength and ease of installation. The interlocking miter corners provide additional durability. No extra metal support is required, making the filter more environmentally friendly.

Specialized Sealant“ A thermoplastic sealant bonds the filter media to the frame on both upstream and downstream sides, eliminating air bypass and enhancing structural rigidity.
