Fiberglass is used in a multitude of applications, particularly as a filtration media. Glass fibers are uniquely suited for filtration because unlike traditional filter fillers, they do not lose efficiency over time.

Why else are fiberglass filters so widely used?

Using Glass Yarn to Make Filters
The type of glass fiber typically used for filtration devices is classified as “Type E” glass.  A stabilizing binder attaches to the glass filaments themselves and provides protection from further processing. The glass yarn is then woven into a broad fabric using conventional textile equipment.

Glass yarn filters are dimensionally stable and have extreme levels of tensile strength. They’re also moisture resistant and have a high tolerance for temperature fluctuations, making them extremely useful for high-temperature industrial applications.

The Benefits of Glass Fiber for Filtration
Glass fibers can conform into nearly any shape imaginable. For that reason, they’re able to be engineered specifically to meet the application and size requirements of various filter panels, boxes, and fans.

The nature of fiberglass provides for high uniformity and consistent performance. Because fiberglass filters do not rely on an electrostatic charge to capture dust or other fine particulates, they don’t lose efficiency over time. These filters have a high dust-holding capacity and can be treated with various substrates such as an antimicrobial coating.

Fiberglass Filter Applications
Fiberglass filters are suitable for a variety of industrial and individual uses. From the medical sector (operating rooms, personal respirators, pharmaceutical processing) to residential homes (HVAC systems, vacuum exhausts, air conditioners), filters made from bonded glass yarns are both versatile and cost-effective.

Because of their efficiency and longevity, fiberglass filters are also used in industrial applications like nuclear containment, coal fired power generation, food processing, and in the production of microelectronic equipment. In many situations, they are considerably cleaner than traditional materials or plastic filters and allow for substantially less risk of contamination from particulates.

Fiberglass filters can be made in nearly any shape or size. To find out whether glass yarn filters make sense for your particular application, contact the expert team at B&W Fiberglass today.
