Advantages of FiltEdge's Acrylic Filter Bag
Moisture-related conditions: Water- and oil-repellent finishes may be considered where moisture and dust characteristics make surface treatment appropriate. Condensation control also depends on process temperature, insulation and operating practice.
Material review: Homopolymer acrylic needle felt may suit selected acidic or hydrolysis-sensitive conditions within the confirmed temperature and chemical limits. Media and finish should be checked against actual process data.
Emission performance: Emissions depend on media grade, construction, installation, collector condition and operating settings. Any target must be reviewed against the project specification and applicable requirements.
Documentation: Available material and inspection documents are confirmed for the selected specification and order.
What’s Acrylic Filter Bags
Acrylic filter bag selection depends on the gas composition, humidity, temperature and dust collector design. Share your drawings, existing bag sample and operating conditions for an application review. Custom construction can be discussed for pulse-jet, reverse-air and mechanical-shaking equipment. Our team reviews technical and after-sales requests during business hours; support arrangements are confirmed for the order.
Acrylic Filter Bag Selection and Classification
Acrylic filter bags can be specified by material, surface treatment and construction. Share your operating conditions or drawings so our team can review the available options during business hours. The following configurations are provided for reference.
Standard Acrylic Filter BagYou can use it in wet, acidic, working temperature below 125 ℃ working conditions.
Water and Oil Repellent Acrylic Filter BagIt can resist condensation and is suitable for working conditions that are humid and prone to condensation leading to clogging of filter bags.
ePTFE Membrane Laminated Acrylic Filter BagAfter coating ePTFE, the precision can be improved, and it can be applied to the working condition that has the demand for ultra-low emission (<5mg/10mg).
Acrylic Filter Bag Performance
The excellent performance of Filtedge’s acrylic filter bags reduces costs and increases efficiency in your production.
Continuous operating temperature of 125°C, with a maximum instantaneous temperature of 140°C.
It exhibits excellent hydrolysis resistance, making it suitable for use in equipment operating in high-humidity environments.
Suitable for gases such as SO2/SO3/NOX/HCL, phosphides, and organic acids.
Low thermal shrinkage rate, stable structure, resistant to deformation, and long service life.
More cost-effective than other filter bags.
Suitable for various industrial dust collection systems such as pulse jet, reverse air, and shaking.

Applications of Acrylic Filter Bags
If your operating conditions involve low temperatures, humidity, and acidic gas dust, Filtedge’s acrylic filter bags are highly suitable. Examples include coal mill dust in cement plants, HCL/SO2/NOX acidic gases from waste incineration, asphalt mixing plants, and flue gas treatment in coal-fired power plants.
Acrylic Filter Bag Material
FiltEdge’s acrylic filter bags are available in 2 main materials, homopolymer acrylic or copolymer acrylic. The most commonly used fabric is 350-600gsm needle felted homopolymer acrylic. Homopolymer acrylic is 100% pure, high quality acrylonitrile needle felted. It can withstand higher temperatures (125°C) than copolymerized acrylic. In wet, acidic applications, homopolymer acrylic filter bags are less likely to corrode and break, and the service life can be directly increased by a factor of 2, reducing your long-term consumable costs and labor costs for bag changes.
Shape of Acrylic Filter Bag
We can manufacture both circular acrylic filter bags and envelope acrylic filter bags for you. However, circular acrylic filter bags are chosen by our customers the most because they have the widest range of applications. You can choose according to your dust collector and working condition requirements.
Acrylic Filter Bag Cleaning Method
FiltEdge’s acrylic filter bags have excellent dust cake stripping performance in humid acidic environment, not easy to paste and stick bags, very suitable for use in high-pressure pulse jet dust collector. With each pulse spray stroke, the dust can be easily shaken off, so that your dust collector can maintain low resistance operation for a long time. It is corrosion-resistant and durable, which reduces the number of times you have to replace the filter bag frequently and can realize the purpose of cost reduction and efficiency for you.
Acrylic Filter Bag Surface Post-Treatment
Surface-treatment options include singeing, calendering, water and oil repellency, PTFE impregnation, membrane lamination and antistatic treatment. Suitability depends on the application. No treatment alone establishes safe use with combustible dust; the complete system requirements must be reviewed.
Acrylic Filter Bag Installation Structure
FiltEdge’s acrylic filter bags have the most common top configurations with snap band and flange type; acrylic filter bag bottom structure with reinforced disc bottom. These structures have excellent solidity and sealing, and you can use them to remove dust efficiently on pulse dust collectors. If your factory is using a reverse air baghouse, you can not easily replace the dust collector, and you need to face the high emission standards, we can customize the hanger cap, tie-on top, raw edge needle felt acrylic filter bag for you.

Polyester filter bags work at about 110℃, acrylic filter bags can work continuously in 125℃. And the biggest advantage of acrylic filter bags is that they are not easily hydrolyzed and have excellent acid resistance. If you are using the filter bag in the environment with water vapor, high temperature and sulfur, then the acrylic filter bag extends the service life 2-3 times longer than the polyester filter bag, which can save you cost as well as reduce the frequency of changing the bag, and the comprehensive cost-effective will be higher.
FiltEdge’s acrylic filter bags are manufactured to tight tolerances of ±2mm. We measure the folded width, overall length, and diameter of the bag before it leaves the factory. If a fit problem occurs, provide the order details and measurements for review. Any replacement, return or refund is handled according to the agreed order terms.
The requested emission level must be assessed for the complete dust collection system and operating conditions. An ePTFE membrane option can be reviewed, but the filter bag alone does not guarantee regulatory compliance. Confirm performance requirements and validation arrangements before ordering.
Yes, they can be used. Typically, blowback filters are more commonly used with woven filter bags, but for larger blowback filtration plants, FiltEdge can provide you with coated acrylic needle punched filter bags with anti-collapse spreader rings for blowback filtration, which will stabilize filtration, prevent sticking, and reduce emissions to meet stringent environmental standards.
