Aokai manufactures replacement and custom filter bags for pulse-jet, reverse-air and shaker dust collectors.
Dust collector filter bags are essential filtration components in industrial dust collection systems. They capture particulate matter from dust-laden air streams through mechanisms such as interception, inertial impaction, and diffusion, making them ideal for high-dust environments.
Aokai ENVIRONTEC offers customized filter bag solutions tailored to specific dust characteristics (particle size, humidity, temperature, and corrosiveness), as well as equipment type and cleaning method, ensuring reliable and long-term stable performance.
We provide full-spectrum industrial dust collection solutions categorized by operational thermal demands and fabric structures. From Ambient & Mid-Temp Filter Bags (up to 160°C) for cost-efficient reliability to High-Temp Filter Bags (160°C+) engineered for extreme thermal endurance. Available in both Needle Felt and Woven Fabric constructions, featuring 12 core premium materials and 100% bespoke customization to match your specific baghouse operating conditions.

Filter Bags for All Baghouse Styles
Aokai manufactures filter bags of any baghouse styles, configurations, and sizes.
Baghouse Style
Pulse Jet Filter Bags
Aokai manufactures pulse-jet filter bags. With supporting cages, these bags allow airflow from the exterior of the bag and exiting through the interior. Top constructions consist of a snap band, flange top, ring top, soft cuffs, or raw edge. Bottom removal bags are constructed with a raw top or soft cuff. Top and bottom removal filter bags have disc bottoms. A wear strip is sometimes attached to the bottom portion of the filter bag to prevent any premature wear from bag-to-bag and bag-to-cage abrasion.
Baghouse Style
Reverse Air Filter Bags
Aokai manufactures a wide variety of reverse-air bags. Typical top designs are strap top, loop top, cord top cuff, compression band with steel caps, or grommet top bags. Bottoms include raw edge, cuffed, compression band, or beaded cuff. Anti-collapse rings of mild steel, stainless steel, and other alloys are placed along the bag at the proper points for maximum cleaning efficiency.
Baghouse Style
Shaker Filter Bags
Aokai provides a wide variety of filter bags for use in shaker-type collectors. We manufacture filter bags from woven and shaker felt. We offer various types of top attachments to work with the shaker mechanism you have, whether it is a loop, hanger, strap, grommet, or your custom design. Our bottom attachments can be made with snap bands, corded cuffs, or reinforced cuffs for extra wear protection.
Filter Bags by Industry Application
The application scenarios of dust collector filter bags are essentially determined by three factors: dust characteristics (concentration, particle size, composition), working conditions (temperature, humidity, corrosiveness), and industry standards.
Steel & Metallurgy
Cement & Building Materials
Power Generation
