Industrial Filter Bag — Dust Collector Filter Bags
Industrial filter bags from LYH cover the full range of baghouse dust collection applications — cement, steel, power generation, waste incineration, chemical processing, woodworking, food handling, and any process where particulate emissions must be controlled. Buyers choose LYH industrial filter bags when they need 11 fiber options matched to specific operating temperatures, gas chemistries, and emission targets — from cost-effective polyester for ambient dry dust to PTFE and FMS composites for ultra-high-temperature acid flue gas.
We supply industrial dust collector filter bags from China with custom size discussion, full material and surface treatment matching, and engineering support across the complete product line. If your project requires a specific bag dimension, fiber selection, or emission compliance target — from standard ≤ 50 mg/Nm³ down to ultra-low ≤ 5 mg/Nm³ — we can review the RFQ and pair the right filter bag to your dust collector and process conditions.

Filter Bag Material Selection Quick Guide
Choosing the right industrial filter bag depends on five primary factors. Use this decision guide to narrow your selection, then visit the individual product page for full specifications.
| Factor | Selection Guidance |
|---|---|
| Operating Temperature | Match continuous gas temperature to the bag’s continuous rating with safety margin. Check both dry and moist temperature ratings. |
| Gas Chemistry | Acidic (SOx, HCl) → PPS, PTFE, P84; Alkaline → PP, PTFE; Oxidizing (O₂, NOx) → PTFE, PPS+PTFE composite; Halogens (HF, Cl₂) → PTFE only |
| Humidity / Hydrolysis Risk | Saturated or humid streams → Acrylic, PPS, PTFE; avoid PET and aramid in prolonged moist heat |
| Dust Properties | Combustible/explosive → Anti-static required; Fine PM2.5 → P84 or PTFE membrane; Abrasive → Aramid or FMS composite; Sticky/oily → PTFE membrane or W&O repellent finish |
| Emission Target | Standard ≤ 50 mg/Nm³ → singed/glazed needle felt; Low ≤ 20 mg/Nm³ → calendered with optional treatment; Ultra-low ≤ 10 mg/Nm³ → mandatory ePTFE membrane lamination |
