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 membrane lamination 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.
