Asphalt Plant Filter Bags
High-Temperature Nomex & Fiberglass Baghouse Filter Bags for Batch Mix, Drum Mix & Mobile Asphalt Plants
Engineered by ECOGRACE — ISO 9001 & ISO 14001 Certified
Asphalt Plant Filter Bags — Engineered for Extreme Conditions
ECOGRACE asphalt plant filter bags are purpose-built for the extreme combination of high temperature (160–200°C), bitumen fume, hydrocarbon vapor, moisture cycling, and abrasive mineral dust generated during hot mix asphalt (HMA) production. Whether your operation runs a batch mix plant, drum mix plant, or mobile asphalt plant, our asphalt baghouse filter bags deliver reliable dust collection performance under the most demanding conditions.
Our asphalt mixing plant dust collector bags achieve ≥99.9% particulate capture efficiency with outlet emissions consistently below 20 mg/Nm³ — meeting the strictest emission standards in Australia, Canada, New Zealand, and South Africa. Each asphalt plant filter bag features NOMEX (meta-aramid) or fiberglass substrate with oleophobic surface treatment, engineered to prevent bitumen condensation blinding that destroys standard polyester bags within weeks of service.
With proven installations across OEM brands including Marini, Ammann, Benninghoven, Lintec, Astec, XCMG, SANY, and D&G Machinery, ECOGRACE provides drop-in replacement asphalt baghouse filter bags that meet EU TA Luft, US EPA AP-42, AU NPI, and the most demanding regional air quality requirements.
Recommended Filter Media for Asphalt Plant Filter Bags
Nomex Filter Bags for Asphalt Plant (Meta-Aramid)
“The gold standard for asphalt plant filter bags worldwide.”
Nomex filter bags for asphalt plant operate continuously at 200°C with exceptional mechanical strength, abrasion resistance, and flex fatigue endurance. Oleophobic and hydrophobic surface treatment prevents bitumen condensation and moisture blinding. NOMEX 554 and NOMEX NXT grades provide the optimum balance of filtration efficiency, dust cake release, and 18–30 months service life.
Fiberglass Filter Bags for Asphalt Plant
“Continuous operating temperature up to 280°C for extreme asphalt plant environments.”
Fiberglass filter bags with PTFE membrane and acid-resistant coating provide maximum thermal safety margin and superior dimensional stability for reverse-air baghouse systems. Ideal for drum mix plants processing high-RAP content with waste oil fuel.
PTFE Membrane Lamination
“Ultra-low emission <10 mg/Nm³ for plants in urban areas and strict emission zones.”
PTFE membrane asphalt plant filter bags achieve <10 mg/Nm³ outlet emission while maintaining the lowest pressure drop and best dust cake release. Essential for plants near residential zones with strict opacity limits in Australia, Canada, and New Zealand.

Asphalt Plant Filter Bags by Plant Type
Batch Mix Asphalt Plant
Variable exhaust temperatures (120–200°C) and fluctuating dust loading. Our Nomex filter bags with oleophobic treatment handle thermal cycling with consistent performance across seasonal production schedules common in Canada, Australia, and New Zealand.
Drum Mix (Continuous) Plant
Sustained high-temperature operation (160–190°C) with continuous bitumen fume exposure. Nomex filter bags with PTFE membrane are essential to prevent cumulative bitumen blinding over 12–24 months of continuous operation.
Mobile Asphalt Plant
Compact baghouse systems operating at higher air-to-cloth ratios (1.5–2.0 m/min). Our filter bags deliver exceptional mechanical strength and abrasion resistance for portable operations across remote project sites in South Africa, Australia, and Canada.
RAP (Reclaimed Asphalt) Processing
Plants processing 20–50% RAP generate significantly higher bitumen fume and VOC concentrations. Premium oleophobic treatment or PTFE membrane is required for reliable long-term operation.

Frequently Asked Questions — Asphalt Plant Filter Bags
Q: What filter bag material is best for asphalt plant baghouse?
NOMEX (meta-aramid) with oleophobic surface treatment is the industry standard for asphalt plant filter bags. NOMEX provides 200°C continuous temperature rating with excellent abrasion and hydrocarbon resistance. For strict emission limits (<10 mg/Nm³), upgrade to NOMEX with PTFE membrane. Fiberglass filter bags are recommended only when exhaust temperature consistently exceeds 200°C.
Q: Are your filter bags compatible with Ammann, Marini, or Astec plants?
Yes. Our asphalt baghouse filter bags are precision-engineered to meet OEM specifications for Ammann, Marini (Fayat), Benninghoven (Wirtgen/John Deere), Lintec & Linnhoff, Astec Industries, XCMG, SANY, D&G Machinery, and Nikko. Provide your bag dimensions (diameter x length), snap-ring type, and plant model for exact-fit replacement.
Q: How long do Nomex filter bags last in asphalt plant service?
Under standard operating conditions, our Nomex filter bags for asphalt plant provide 18–30 months service life. With PTFE membrane, service life extends to 24–36 months. Actual life depends on operating temperature, RAP percentage, cleaning pressure, and maintenance practices.
Q: Do you ship to Australia, Canada, New Zealand, and South Africa?
Yes. We regularly supply asphalt plant filter bags to customers across Australia, Canada, New Zealand, and South Africa. Standard delivery 15–20 days via sea freight. Express air freight available for urgent requirements. Free samples shipped via DHL/FedEx within 3–5 days.
