Finedust Filter Type G90
Design and Construction:
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.
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.
The G90 enclosure frame is a special die cut solid craft-board with extra moisture resistance, designed to prevent collapse under extremely humid conditions.
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.
The G90 filters have an average efficiency of 30% to 60%. All testing is done in accordance with the ASHRAE 52-1 standard guidelines. The G90 filter has more media area for improved performance and longevity. The G90 filter is designed for applications requiring higher efficiency and arrestance. All units are available in 1”, 2”, and 4” thicknesses.
All Sizes Available:
The G90 1”, 2”, and 4” filters are available in unlimited sizes. This will make increased efficiency available in all applications.
