What are high temperature filter bags?
High temperature filter bags are industrial dust collector bags engineered to operate above 130°C, where standard polyester or polypropylene media would fail. Made from heat-resistant fibers — PTFE, Nomex (aramid), PPS (Ryton), fiberglass, or P84 (polyimide) — these high temperature filter bags withstand continuous operation from 150°C to 260°C with high chemical resistance, making them essential for cement, power, incineration, asphalt, and metallurgy industries.

How to Select the Right High Temperature Filter Bags
Selecting the correct high temperature filter bags requires matching media properties to your operating environment. Use this 4-factor framework:
Operating Temperature
<190°C → PPS / Nomex
190–240°C → Nomex / P84
>240°C → PTFE / Fiberglass
Gas Chemistry
Strong acid → PTFE / PPS
Hydrolysis → PTFE / Fiberglass
Alkaline → PTFE / Nomex
Dust Properties
Abrasive → Nomex / P84
Sticky → PTFE membrane
Sub-micron → P84 / ePTFE
Emission Target
<5 mg/Nm³ → PTFE membrane
<20 mg/Nm³ → P84 / Nomex
<50 mg/Nm³ → Fiberglass

High Temperature Filter Bags FAQ
Common questions about high temperature filter bags, materials, and selection for industrial dust collection.
What temperature is considered high for filter bags?
Filter bags are classified as high temperature filter bags when designed to operate continuously above 130°C (266°F). Standard polyester (PE) bags fail above this point. High temperature filter bags use specialized fibers — PPS (190°C), Nomex (204°C), P84 (240°C), PTFE (260°C), or fiberglass (260°C) — that maintain mechanical and chemical stability at elevated temperatures.
Which high temperature filter bag material is best for my application?
The best high temperature filter bags depend on four factors: (1) operating temperature, (2) gas chemistry (acid/alkali/hydrolysis), (3) dust properties (abrasive/sticky/sub-micron), and (4) emission target. PTFE filter bags for incineration and chemical, Nomex / aramid filter bags for asphalt and cement, PPS / Ryton filter bags for coal power, fiberglass filter bags for cement and steel, P84 filter bags for cement kiln tail.

What is the difference between Nomex and aramid filter bags?
Nomex filter bags and aramid filter bags are the same product. Nomex is the brand name of meta-aramid fiber registered by DuPont, while “aramid” is the generic chemical category. Both refer to high temperature filter bags made from m-aramid fiber that operate continuously up to 204°C with excellent abrasion and flex resistance — the gold standard for asphalt plants and cement raw mills.
What is the difference between PPS and Ryton filter bags?
PPS filter bags and Ryton filter bags refer to the same fiber. PPS (polyphenylene sulfide) is the chemical name; Ryton is the brand name registered by Phillips Petroleum (now Solvay). These high temperature filter bags operate at 190°C continuous and are the standard choice for coal-fired power plant baghouses due to outstanding acid and hydrolysis resistance in moist sulfur-rich flue gas.
What is the maximum operating temperature for high temperature filter bags?
The maximum continuous operating temperature for high temperature filter bags is 260°C (500°F), achieved by both PTFE and fiberglass media. Surge tolerance reaches 280–290°C briefly. Above 260°C continuous, ceramic filter elements are required. Most high temperature dust filter bags in cement, power, and incineration operate in the 150–230°C range.
How long do high temperature filter bags last?
Service life of high temperature filter bags varies by material and operating environment: PTFE 3–5 years (longest), Nomex / P84 2–4 years, PPS / fiberglass 2–3 years. Properly sized bags with correct media selection can extend life by 30–50%. Premature failure usually traces to chemical attack, hydrolysis, or thermal excursion above the bag’s rated temperature.
Can you supply OEM-replacement high temperature filter bags?
Yes. ECOGRACE manufactures OEM-compatible high temperature filter bags for all major baghouse brands including Donaldson, Camfil, Nederman, BWF, Albany, Mikropul, GE Power. Provide your existing bag dimensions (diameter, length, top/bottom configuration) or original part number, and we produce drop-in replacement high temperature filter bags with same materials and performance — at 30–50% lower cost. 3–5 week lead time.
What is the price of high temperature filter bags?
Pricing for high temperature filter bags depends on material, dimensions, and finish. Approximate ranges per bag (160mm×6m standard size): Fiberglass USD 18–35, Nomex USD 25–45, PPS USD 30–55, P84 USD 45–75, PTFE needle felt USD 60–120, PTFE membrane USD 80–150. ECOGRACE factory-direct pricing is 30–50% below Western OEM brands for equivalent quality.
What is the minimum order quantity for high temperature filter bags?
Standard sizes: MOQ from 50 pieces. Custom sizes requiring special tooling: MOQ may be higher. We supply 1–5 sample high temperature filter bags for testing and qualification before bulk orders. Contact us with your specifications for exact MOQ and lead time.
