Dust Collector Filter Bags
Industrial Filter Bags, Matched to Your Process
Novazure dust collector filter bags are designed for industrial baghouse filtration and replacement applications. Material options include polyester, PPS, aramid, and PTFE-based media, with suitable surface treatments and construction options available for different operating conditions.
Filter bags can be specified according to your dust characteristics, operating temperature, bag dimensions, and installation requirements. Share your existing filter specifications, drawings, or samples to discuss suitable replacement filter bags and receive a quotation.
Industrial Filter Bag Materials & Options
Polyester Filter Bags
A widely used filter media option for general industrial dust collection, offering a practical choice for suitable dry, moderate-temperature applications.
PPS Filter Bags
Polyphenylene sulfide filter media for selected elevated-temperature and chemically demanding applications, subject to gas composition and operating conditions.
Aramid Filter Bags
Heat-resistant synthetic filter media for suitable higher-temperature dust collection processes where thermal and chemical conditions are verified.
PTFE Filter Bags
PTFE-based filtration media for applications requiring strong chemical resistance and specialized performance under compatible operating conditions.
Fiberglass Filter Bags
Glass fiber filtration media for selected high-temperature industrial processes, with construction and cleaning requirements evaluated for the application.
PTFE Membrane Filter Bags
Membrane-laminated filter bags designed to support surface filtration and dust cake release, with the base fabric selected for the operating conditions.
Special Configurations
Antistatic Filter Bags
Filter media with conductive or antistatic features for applications requiring electrostatic charge control. Additional system-level safety measures may be required.
Pleated Filter Bags
Pleated filter elements for selected baghouse applications where increased media area or replacement configurations are being evaluated.
Filter bag material, surface treatment, and construction should be selected according to temperature, gas chemistry, moisture, dust properties, and the existing baghouse configuration.
How to Choose the Right Filter Bag Material
Operating Temperature
Consider continuous gas temperature, peak temperature, and possible temperature fluctuations when evaluating filter bag media.
Gas Chemistry
Evaluate acids, alkalis, oxidation, and other chemical components that may affect filter media compatibility and service life.
Moisture & Condensation
Review humidity, process dew point, condensation risk, and potential dust buildup or filter blinding during operation.
Dust & Cleaning Conditions
Consider particle size, abrasiveness, dust loading, and the existing pulse-jet or other filter cleaning system.

Frequently Asked Questions About Filter Bags
How do I choose the right filter bag material?
The appropriate filter bag material depends on your operating temperature, gas chemistry, moisture level, dust characteristics, and cleaning system. Common options include polyester, PPS, aramid, PTFE, and fiberglass.
Share your process conditions and existing filter specifications so the material options can be reviewed before selection.
How do I measure a replacement dust collector filter bag?
The main dimensions are the bag diameter and overall length. You should also identify the top opening, fixing method, bottom construction, and supporting filter cage dimensions.
If you are unsure how to measure a used filter bag, send us photos, an existing drawing, or a sample. The final dimensions and tolerances should be confirmed before manufacturing replacement bags.
Can you manufacture replacement filter bags for an existing baghouse?
Yes. Custom replacement filter bags can be evaluated for existing industrial baghouse systems, including equipment supplied by other manufacturers.
Compatibility depends on the filter dimensions, material, top and bottom construction, filter cage, and installation requirements. Existing samples or technical drawings can help with specification matching.
How long do industrial dust collector filter bags last?
Filter bag service life varies according to filter media, operating temperature, dust loading, chemical exposure, moisture, and cleaning frequency. There is no single replacement interval suitable for every baghouse.
Regularly monitor differential pressure, filtration performance, and the physical condition of the bags. Replace damaged or deteriorated bags when inspection and operating conditions indicate replacement is necessary.
Is there a minimum order quantity for custom filter bags?
Minimum order quantities may vary depending on the filter media, bag dimensions, construction requirements, and manufacturing arrangements.
Please provide your required quantity and specifications. We can review the order requirements and confirm the applicable minimum quantity and quotation.
What is the production and delivery lead time for filter bags?
Production lead time depends on the selected filter material, construction complexity, order quantity, and current manufacturing arrangements.
After reviewing your specifications, we can provide an estimated production lead time with the quotation. Shipping time will depend on the destination and agreed transportation method.
