2-Ply Depth-Loading Panel & Link Filters

This 2-ply synthetic media uses a depth-loading structure designed to capture larger particles in the first layer and progressively smaller particles through the downstream layer. Compared with surface-loading media, depth-loading reduces the rate of resistance increase, supporting lower energy use and longer service life.

  • Helps eliminate bypass between adjacent filters
  • Keeps coils cleaner to maintain system efficiency
  • Supports energy savings via lower resistance rise
  • Resistant to moisture and mold
  • Reduced filter failure risk; no paperboard components
  • MERV 6 (per ASHRAE 52.2-2017)

Construction & Application Notes

  • Media: Two deniers of synthetic fibers for progressive depth loading
  • Support: Internal galvanized wire ring sealed between media layers
  • No frame gap in link configurations to minimize bypass
  • Continuous operating temperature: 200 °F
  • Meets ANSI/UL-900 requirements
  • Special sizes available
  • Width and height are interchangeable; actual size reflects internal wire support (minimum 1/2" perimeter selvedge)
  • Options: Antimicrobial treatment, link configuration, roll-up configuration

Good Practices

  • Use link filters where eliminating gaps between adjacent filters is critical.
  • Verify sizing: nominal vs. actual dimensions may differ due to internal support.
  • Replace based on pressure drop and application requirements to maximize energy savings.

This economical 2-ply panel and link filter is designed as an upgrade and replacement for traditional fiberglass disposable filters. It provides a cost-effective option where reliable filtration is required.

The selvedge edge of the panel and link filter creates a seal that eliminates bypass of unfiltered air – a common problem with cardboard-framed filters. Unlike cardboard, these filters resist moisture and mold, reducing the risk of damage, collapse, or microbial growth within HVAC systems. Available as both ring panels and links in standard and custom sizes.

Key Features

  • Cost-effective with consistent performance
  • Eliminates dirty air bypass
  • Moisture resistant
  • Mold resistant
  • Available in custom sizes
  • Internal wire support for strength
  • Fits side, front, or rear access housings
  • Lower shipping and storage costs
  • Reduced handling damage

Construction & Application Notes

The selvedge edge of each panel and link filter is engineered to seal tightly within housings, helping eliminate unfiltered air leakage. Panels are suitable for a wide range of HVAC applications requiring reliable, moisture-resistant performance.

2‑Ply Panels, Links & Cubes

High‑loft polyester media arranged in two graduated layers (coarse → fine) for depth loading and longer life. Panels are heat‑sealed around an internal galvanized wire frame and feature a self‑gasketing perimeter to reduce air bypass. Linkable panels can simplify handling and reduce change‑out time.
