Crafted from weather-resistant ultra-fine fiberglass, this product replaces conventional fragile, poor weather-resistance fiberglass filter materials. It features a fluffy 3D three-dimensional structure with fine fibers and uniform pores, boasting four core merits: high dust holding capacity, low air resistance, high tensile strength and stable performance.

Fibreglass bag filter media is the roll stock for building pocket and frame filters where ordinary glass fibre would not survive. Conventional fibreglass is brittle and loses performance in humid or high-temperature air; the weather-resistant grade here keeps its structure, which is what makes it usable upstream of HEPA in a paint booth or a drying line.

It is supplied as a fluffy three-dimensional mat at 2.5 mm and 105 to 110 g/m², in F6, F7 and F8. The loft is the working part: dust travels into the depth of the media instead of sitting on the face, so the roll can be cut to any pocket length, fitted into a frame, and still hold a low resistance until it is genuinely loaded.

The applications follow from that: bag filters and frame filters in central air conditioning, fresh-air filtration, and pre-filter protection for HEPA stages in hospitals, food plants and precision electronics workshops.

## Application Scenarios


## Why Choose Whalesense Fiberglass Bag Filter Media

- Upgraded material to eliminate drawbacks of traditional fiberglass Ordinary fiberglass is fragile, easily broken, poor in weather resistance and short-lived. Whalesense weather-resistant fiberglass features high strength, no fiber shedding, anti-aging, temperature and moisture resistance, maintaining consistent performance amid environmental changes for long-term reliability.
- High dust holding capacity & long service life for lower overall cost The fluffy 3D structure delivers large dust storage capacity and stable air resistance, extending replacement cycles and cutting labor and material maintenance costs for long-term cost savings.
- High tensile strength for damage-free installation and operation Superior tensile strength versus standard fiberglass, resistant to pulling and vibration with minimal fiber shedding, free from breakage during bag or frame filter assembly.
- Full F6-F8 grades with clear color coding for wide compatibility Distinct color marking: Apricot Yellow F6, Lavender F7, Light Yellow F8. Covers most medium-efficiency ventilation and industrial scenarios for one-stop selection without repeated comparison.
- Flame-retardant & chemically stable for versatile working conditions Class A non-combustible, acid & alkali resistant, anti-mold. Adaptable to high humidity, high temperature and dusty environments with broader application scope than synthetic fiber media.

## Technical Specifications

Traditional fiberglass is fragile and poor in weather resistance. Whalesense weather-resistant fiberglass delivers high dust holding capacity and extended service life with consistent performance regardless of environmental fluctuations.
