  • Finedust Filter Type G90

    Design and Construction:
    Filter Media

    The G90 series is produced using a special pretested blend of cotton and polyester fibres. The G90 media has extra pleats (more sq. ft. of space) for increased dust holding capacity.

    Media Support

    The media is bonded to a special galvanized steel expanded metal support grid with a 95% open face area. This allows increased utilization of the filter media. The media and metal combination is designed to prevent sagging or collapse and is bonded tightly to the frame, eliminating any possibility of air bypass.

    Enclosure Frame

    The G90 enclosure frame is a special die cut solid craft-board with extra moisture resistance, designed to prevent collapse under extremely humid conditions.

  • Applications:

    The G90 Series is designed for a longer lifetime with reduced maintenance costs. All G90 filters are designed for easy installation in existing HVAC systems and perform well as the primary filter or as a prefilter for extending the life of a high efficiency filter.

  • Type Description:
