Aokai manufactures ultra-low emission filter bags for industrial baghouses operating under increasingly stringent particulate emission requirements.<\/span><\/p>\n

Our solutions combine application-matched filter media, ePTFE membrane surface filtration, controlled bag construction and accurate bag-to-cage fit. They are designed for projects targeting outlet dust concentrations below 10 mg\/Nm\u00b3 and, where the complete baghouse system allows, below 5 mg\/Nm\u00b3.<\/span><\/p>\n

Available substrates include polyester, acrylic, aramid, PPS, P84, fiberglass and PTFE. Every filter bag can be customized to match the temperature, gas chemistry, dust properties, cleaning method and dimensions of the existing dust collector.<\/span><\/p>\n

What Are Ultra-Low Emission Filter Bag?<\/h2>\n<\/div><\/div>

Ultra-low emission filter bags are industrial dust collector bags developed for baghouses that need to maintain a very low outlet particulate concentration.<\/span><\/p>\n

For most projects, \u201cultra-low emission\u201d refers to a target below 10 mg\/Nm\u00b3. More demanding plants may require outlet emissions below 5 mg\/Nm\u00b3.<\/span><\/p>\n

Compared with conventional needle felt, an ultra-low emission filter bag normally uses a high-efficiency filtration surface, such as an ePTFE membrane filter bags<\/a>, to prevent fine particles from penetrating deeply into the filter media.<\/span><\/p>\n<\/div><\/div><\/div><\/div>

How Aokai Supports Ultra-Low Emission Performance<\/h2>\n<\/div><\/div>

1. High-Efficiency ePTFE Membrane<\/h3>\n<\/div><\/div>

Aokai can laminate an ePTFE membrane onto different needle-felt or woven substrates.<\/span><\/p>\n

The microporous membrane provides surface filtration and helps capture fine particles, including dust that would otherwise penetrate conventional felt. Because most of the dust remains on the surface, the filter cake is generally easier to remove during cleaning.<\/span><\/p>\n
