Red Industrial

The Red Industrial filter is designed for use in industrial and commercial HVAC systems. Suitable for installation where dust-loading conditions are particularly heavy, Red Industrial filters also serve as excellent prefilters to higher efficiency filters.


Dust Holding Capacity

The fibers on the air-entering-side of the media pad are interlaced with an open pattern that becomes increasingly tighter toward the air-leaving-side. This unique construction allows the filter to hold more dirt throughout its entire depth. The Red Industrial filter can be expected to last longer than any 2” or 4” pleated panel filter currently available



The Red Industrial filter comes in 2” and 4” depths. The 2” filter uses 3” nominal thickness media while the 4” filter uses 5” nominal thickness media


Initial Resistance

The initial resistance of the Red Industrial is 0.32” in W.G. for the 2” filter depth and it is 0.38” in W.G. for the 4” filter depth


Final Resistance

The final resistance of the Red Industrial is 0.60 ” W.G. for both 2” and 4” depths

Key Features & Benefits

  • Increased Dust Holding Capacity:
    progressive density media
  • Very High Compression Strength:
    permits air to flow freely through the filter with a gradual rise in resistance
  • Heavy Duty Construction:
    constructed using moisture resistant beverage board with expanded metal
  • Moisture Resistant:
    entire frame perimeter is secured by a waterproof wrap
  • Industrial Grade Adhesive:
    heavy dirt loading applications
  • 2 – 4” Loops on Pockets:
    using 3” – 5” nominal thickness media • MERV 8 Performance

Performance Data

*Red Industrial cells can be operated at higher than rated face velocities. Individual air flow and dust concentrations may vary. For best performance we recommend replacing the Red Industrial filter between 0.6” & 0.75” (150 – 188Pa) final resistance.

Temperature Limitations: Red Industrial filters are designed for continuous operating temperatures up to 150°F (65°C).
