At Jiangsu Aokai, we define high temperature filter bags as dust collector bags that are designed for continuous operating temperatures above 160°C (320°F). These filter bags are engineered to withstand elevated temperatures, corrosive gases, and abrasive dust while maintaining stable filtration efficiency and mechanical strength.
Why the 160°C Threshold Matters？
Standard polyester filter bags are typically recommended for continuous use up to about 130–150°C. Once the operating temperature exceeds 160°C, specialized high temperature filter media are required to prevent:
- Thermal shrinkage
- Loss of tensile strength
- Premature bag failure
- Increased emissions
- Unplanned downtime

How do I choose the right material for my high-temperature application?
Selection depends on four key factors: continuous operating temperature, gas chemistry (acid/alkali levels), moisture content, and dust abrasiveness. For example, PPS is excellent for high moisture and acids, while P84 is preferred for high-efficiency capture of fine particles.
Can your filter bags achieve emissions below 5mg/Nm^3?
Yes. By applying a PTFE membran laminasyonu to our high-temperature felts (like Fiberglass or Nomex), we can achieve ultra-low emissions while maintaining excellent dust cake release and low pressure drop.
What is the typical lifespan of your high-temperature filter bags?
While lifespan varies by industry, our bags are engineered to last 20% to 30% longer than standard alternatives due to our precision fiber-blending and heat-setting processes.
Do you provide customized sizes and configurations?
Absolutely. We manufacture custom filter bags to fit all major baghouse brands. We can adjust the length, diameter, and top/bottom configurations to meet your specific hardware requirements.
