LargeEfficiency:
Per ASHRAE 52.1-1992 standard, the filters have an average atmospheric dust spot efficiency range 45-50%, 60-65%, 80-85% and 90-95% (in NBS Test Method); per ASHRAE 52.2, the efficiency is MERV9, MERV11, MERV12 & MERV14. Operating face velocities up to 750FPM are available for certain models.
Media:
G-Series bag is fabricated using a special ultra fine fiberglass media w/0.25'' thickness reinforced by an integral non-woven backing. Using a variety of materials, the range of filtration efficiencies can be spanned from 45-50% to 90-95%.
Sealant
Each stitch of pocket is sealed with a special adhesive to prevent the possibility of contaminant leakage or media break-off.
frame:
G-Series Bag Filter consists of a series of individual pockets, which are bonded to a corrosion-resistant header frame. Media and metal frame are glued to ensure product integrity during operation.
