ENDUREX HD: Heavy Duty High Capacity Pleated Air Filter

This filter is a game changer, made with the heaviest high wet-strength board frame, 2x thicker wire, best-in-class pressure drop, and a mechanical media for the most demanding applications. If you’re a fan of Camfil’s 30/30 Dual 9, then you will love the Endurex HD. Compared side by side, the Endurex HD costs less to buy and is cheaper to operate due to its lower pressure drop. Simply put, it offers one of the longest service lives of any filter available on the market today.

Features

  • Frame: The filter’s frame is crafted from a heavy, moisture-resistant beverage board, enhancing durability and resistance to moisture—a critical factor in preventing filter degradation.
  • Pleat Support: With the thickest expanded wire for pleat support, the Endurex HD maintains its shape and function even under challenging conditions.
  • Exceptional Filtration with MERV 9/9A: Endurex HD offers MERV 9/9A efficiency, perfectly designed to protect coils and ductwork from particulates while maintaining highly durable uniform size synthetic media that boasts exceptionally low resistance to airflow. This design choice ensures that your systems operate at peak efficiency without compromising on air quality. Click here to refer to our informational MERV rating chart for more details.
  • Mechanical Synthetic Media: It combines the lifespan benefits of glass media with the efficiency and low air resistance of synthetic media, making it an excellent choice for maintaining indoor air quality.
  • Support Grid: A heavy galvanized metal support grid adds further structural integrity, safeguarding the filter’s form and function throughout its service life.
  • Moisture Resistance: This filter is bonded with a moisture-resistant sealant to prevent damage from humidity and moisture.

Benefits

  • Strength: The filter is exceptionally strong, making it suitable for tough commercial and industrial environments.
  • Low Resistance to Airflow: We’ve engineered the Endurex HD’s mechanical synthetic media to reduce the initial pressure drop by 30% or more compared to previous best-in-class products such as Camfil 30/30 Dual 9. This means improved efficiency and less strain on your HVAC systems, leading to lower operational costs.
  • Dust Holding Capacity: The combination of low resistance and high dust holding capacity means the filter can capture and retain a significant amount of particulate matter.
  • Maximized Service Life for Greater Savings: Due to its durability, low initial pressure drop, and high dust-holding capacity, the Endurex HD filter is one of the longest lasting pleated filters available.  Guaranteed. Not only are our filters built to last with higher quality materials, but they also help in significantly lowering your energy costs due to their extended lifespan. The Endurex HD is developed to minimize the need for frequent replacements, thanks to its robust construction and advanced filtration technology which withstands various environmental challenges.
  • Applications: Designed for use in various challenging environments, including:
    • Turbulent Airflow Systems
    • Heavy Load Situations
    • High Flow Rate
    • Extreme Weather Conditions
    • High Moisture Units
    • Long Life Desired

    The Endurex HD excels in each of these areas, making it an ideal choice for facilities requiring robust filtration solutions.
