Columbus Industries SL-3A Panel Intake Filter Pad

CI Panel Filters are a premium solution for intake and pre-filtration, utilizing a progressive density fiber structure and a non-migrating tackifier to achieve optimum airflow and depth loading. These self-sealing panels are available in both single and linked configurations, creating a secure fit that prevents air bypass and ensures all incoming air is thoroughly scrubbed of contaminants. For general-purpose HVAC and booth intake needs, the Columbus Industries SL-3A Panel Filter offers a robust two-layer design. It features a white, multi-denier coarse polyester on the air inlet side to capture larger particles, and a green, fine-denier tackified polyester on the air exit side to trap fine dust. Heat-sealed around a durable metal grid, the SL-3A provides a long service life while significantly improving indoor air quality.

PLEASE NOTE: Shipping Information

These booth filters ship in oversized boxes, with shipping methods and costs determined by the number of boxes ordered.

Orders of 1–3 boxes ship via standard delivery, while larger orders may ship by LTL freight or a combination of freight and standard delivery.

For the best shipping value, we recommend ordering in full-skid quantities of 8 boxes (8, 16, 24, etc.). This helps reduce the shipping cost per box and avoids additional charges for separately shipped boxes.
