Extended Surface Bag Filter (Glass Fiber)

It is designed for those areas requesting a higher degree of air cleanliness. The filter media is available for Fiberglass (G Series) and Synthetic Fiber (S Series). 
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.
The frame is available for Metal Frame.

Features:
G-Series Bag Filter is designed to a V-Shape pocket. The microprocessor control automatic sewing machines can actually control the stitch loosening and continuously to adjust the pockets from 60mm to 20mm. V-Shape pocket design allows every pocket to fully inflate and maintain a proper spacing with adjacent pockets. Clean air can freely exit from front to back.

Efficiency:
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.
