Acrylic Filter Bags
Description
Description of Acrylic filter bags
Acrylic filter bags are a type of filter bag made from acrylic fibers, which is a synthetic fiber that is known for its durability, chemical resistance, and heat resistance. As a dust filtration media, acrylic felt has the following characteristics:
● Particle Retention —— Acrylic filter bags are highly efficient in retaining particles, thanks to their intricate pore structure. These bags can capture particulate matter of various sizes, ranging from coarse to fine particles.
● Chemical Resistance —— Acrylic fibers possess excellent resistance to a wide range of chemicals, making them suitable for filtration applications where aggressive chemicals are being filtered.
● Temperature Resistance —— Acrylic filter bags exhibit good thermal stability, allowing them to withstand elevated operating temperatures. They can typically operate in the temperature range of 120°C to 150°C (250°F to 300°F), making them suitable for filtration processes that involve hot gases or liquids.
● Hydrolysis & Moist Heat Resistance —— Acrylic fibers have low water absorption properties, enabling the filter bags to maintain their filtration efficiency even in high-humidity environments with mild chemical attacks. Where polyester filter bag is not suitable because of potential hydrolysis, acrylic filter bag offers a combination of abrasion and moist heat resistance, particularly under acid conditions.
In addition to these filtration characteristics, acrylic filter bags also offer a number of other advantages, such as:
● Cost-Effective —— Acrylic fabric is relatively inexpensive compared to other high-performance filter media materials, making it a cost-effective solution for a wide range of industrial filtration applications.
● Versatility —— Acrylic filter bags can be customized to meet specific filtration requirements, including shape, size, and surface finishes. Additionally, they can be designed to fit different types of dust collectors, allowing for easy installation and replacement.
● Long Service Life —— Acrylic fibers are known for their durability and resistance to degradation, resulting in extended service life. This reduces the need for frequent replacement, saving maintenance costs in the long run.
● Resistance to Abrasion —— Acrylic filter bags demonstrate excellent resistance to mechanical stress and abrasion, preserving their filtration efficiency over time, even in demanding industrial environments.
Scrim-supported felt is used exclusively in the production of our acrylic filter bags in order to improve filtration efficiency and extend the filter bag life.

Post-treatment of Acrylic Filter Bags
Acrylic filter cloth can be constructed and treated with various options so that they become best suited for various operating conditions, applications, and industries.
● ePTFE Membrane
Adding an ePTFE membrane to an acrylic 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 filter bag life. 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.
● Hydro-Oleophobic Coating
This aids in filtration, adds resistance to water and oils, and improves cake release.
● Static Resistant
Helps to ground the filter bag to eliminate sparks that might cause combustion explosions.
● Singe
Singeing is a finishing process where the surface of the filter media is exposed to a flame or hot gas to burn off the fine and straggly fibers in order to provide a uniform and smooth surface area, which improves dusk cake release, enhanced filtration efficiency, and better air permeability.
The singeing process typically involves passing the fabric over an open flame or through a heated chamber. The heat singes off the protruding fibers without damaging the main structure of the fabric. The process parameters, such as speed and temperature, are carefully controlled to achieve the desired level of smoothness and finish.
● Glazing
Glazing, also known as calendering, is the high-pressure pressing of the fabric by rollers to flatten or smooth the surface. Glazing pushes the surface fibers down onto the body of the filter media to increase and uniform surface life, improve stability, reduce shrinkage, and improve dust cake release.
