Fiberglass Filter Bags
Description
Description of Fiberglass filter bags
Fiberglass filter bags are widely used in industrial dust collection and filtration applications. They are made of fine glass fibers that are woven or nonwoven into a fabric. Fiberglass filter bags offer a number of filtration advantages, including:
● High Filtration Efficiency —— Fiberglass filter bags provide excellent filtration efficiency, typically ranging from 95% to 99.9%, depending on the specific application.
● Fine Particle Retention —— They are effective in capturing small particles, including sub-micron particles, due to their tightly woven or felted construction.
● High-Temperature Resistance —— Fiberglass filter bags can withstand high temperatures of up to 260°C (500°F), making them suitable for applications involving high temperatures.
● Chemical Resistance —— These filter bags are also resistant to a wide range of chemicals, making them suitable for diverse industrial filtration needs.
● Low Moisture Absorption —— Fiberglass has low moisture absorption properties, ensuring minimal moisture retention within the filter bags.
In addition to these filtration characteristics, PPS filter bags also offer a number of other advantages, such as:
● Durability —— Fiberglass filter bags have excellent mechanical strength and are highly durable, ensuring a longer lifespan compared to other filter bag materials.
● High Flow Rate —— They offer a high flow rate due to their smooth surface and non-clogging design, enabling efficient filtration processes.
● Cost-Effective —— Fiberglass filter bags provide a cost-effective solution for industrial filtration needs, as they have a longer lifespan, reducing replacement and maintenance costs.

Post-treatment of Fiberglass Filter Bags
Fiberglass filter bags can be constructed using either woven or nonwoven fiberglass fabrics. In addition, fiberglass filter media can be treated with various options so that they become best suited for various operating conditions, applications, and industries.
● ePTFE Membrane
Adding an ePTFE membrane to a fiberglass filter bag allows the membrane to act as the filter cake. Dust stays on the surface of the membrane and does not get entrained into the fibers of the filter bag, which lengthens the life of your filter bag. It also reduces wear and tear, lower maintenance costs, and energy costs due to easy dust cake release during the cleaning cycle.
● PTFE Coating
The filter media is coated in a bath or spray of liquid PTFE resin. This is done to protect filter bags. The treatment improves the flex life, heat and chemical resistance, and dust release from the filter bags. This increases the service life and filtration efficiency. PTFE finish is commonly used in applications with corrosive chemical compounds, sticky dust, or high moisture contents.
● Silicone & Graphite Treatment
This protects the glass filament from abrasion and adds lubricity. While it provides limited protection against chemical attacks, it is best for non-acidic conditions.
