Acrylic Filter Bag
Acrylic Filter Bags are made from acrylic fibers (also known as polyacrylonitrile fibers) and are typically used in dust collection and air filtration applications.
Product Details
An Acrylic Filter Bag is a type of filtration medium used in dust collection and air filtration systems within industrial environments. It is made from acrylic fibers, which are synthetic polymers known as polyacrylonitrile. These filter bags are designed to handle gases and particulates in various applications, offering specific characteristics that make them suitable for certain conditions. The main features of Acrylic Filter Bags include:
- Hydrolysis Resistance: Acrylic fibers are resistant to degradation in the presence of water, making these filter bags suitable for high-humidity or moist environments.
- Chemical Resistance: They have good resistance to a variety of chemicals, including organic solvents, oxidizing agents, and weak bases, but are generally not as resistant to strong acids and alkalis.
- Temperature Range: Acrylic Filter Bags can typically operate in temperatures up to approximately 125°C (257°F), which is suitable for many low to medium-temperature applications.
- Dimensional Stability: The material maintains its shape and size over time, which is important for consistent filtration performance.
- Durability: Acrylic bags are known for their durability and resistance to abrasion, which contributes to their longevity.
- Customization: They can be tailored to various requirements, such as different finishes or coatings, to enhance performance or durability based on the specific needs of an application.
Acrylic Filter Bags are often used in dust collection systems for industries such as cement, metallurgy, chemical processing, and waste incineration, particularly when the conditions involve moist or moderately corrosive gases.

The features of Acrylic Filter Bags, made from acrylic fibers (polyacrylonitrile), include:
- Hydrolysis Resistance: Acrylic filter bags are resistant to hydrolysis, which is the breakdown of materials due to reaction with water. This makes them suitable for moist environments.
- Chemical Resistance: They have good resistance to a wide range of chemicals, particularly organic solvents, oxidizing agents, and weak alkalis.
- Moderate Temperature Performance: Acrylic filter bags can operate continuously in environments with temperatures up to 125°C (257°F), which is suitable for low to medium-temperature applications.
- Dimensional Stability: The material maintains its shape and size under normal operating conditions, ensuring consistent filtration performance.
- Durability: Acrylic fibers are known for their durability and resistance to abrasion, contributing to a longer lifespan of the filter bags.
- Efficient Particle Capture: The tight weave of the fibers allows for efficient particle capture, helping to maintain clean air emissions and comply with environmental standards.
- Customization: These filter bags can be produced in various sizes and configurations to fit different dust collection systems and can be treated with various finishes to enhance their properties for specific applications.
- Economical: Acrylic filter bags are often more cost-effective than other technical fabrics, offering a good balance of performance and price.
- Antistatic Options: Some acrylic filter bags can have antistatic properties, either through a conductive fiber blend or with a special finish, to safely handle flammable or explosive dust.
Acrylic filter bags are a good choice for applications where moisture resistance and moderate temperature conditions are present, and where an economical but reliable solution for dust collection is required.
