Filter Bag (Dust Collector Bag)
Dust filter bags for bag filters and dust collectors in power plants and cement plants. PET, PPS, Nomex, P84 and PTFE felt options with membrane and anti-static finishes.
Aurora BG dust filter bags are sewn to your tube sheet for baghouses in power plants, cement plants, steel and general industry. PET, PPS, Nomex (meta-aramid), P84 and PTFE felts — with singed, calendared, PTFE-membrane and anti-static finishes — matched to gas temperature, chemistry and emission limits.
Specifications
| Media | Weight (g/m²) | Cont. temp (°C) | Chemistry | Typical duty |
|---|---|---|---|---|
| PET (polyester) | 450–550 | 130 | General, dry | Cement, steel, generic dust |
| PPS (ryton) | 500–600 | 160 | Sulphur / moisture resistant | Coal-fired power baghouses |
| Nomex (m-aramid) | 500–600 | 180–200 | Dry heat | Asphalt, cement kiln |
| PTFE membrane on PPS/PET | 550–650 | 160 / 130 | Fine emission limits | PM limits < 10 mg/Nm³ |
The running-cost view. Bag choice is an emission-compliance decision: PPS for coal-fired sulphur, membrane laminates where mg/Nm³ limits bite. Right media from day one avoids the most expensive retrofit — a second baghouse campaign.
Applications
- Power plant baghouses — coal-fired and biomass FGD dust collection
- Cement plant bag filters — kiln, raw mill and cement mill dedusting

Frequently Asked Questions
Which filter bag material suits a coal-fired power plant?
PPS felt bags are the standard for coal-fired baghouses, offering sulphur and heat resistance. PTFE-membrane PPS bags are used where finer emission limits apply.
How do I select dust collector filter bags?
Match media to gas temperature, moisture and chemistry first, then to emission limits: PET for dry generic dust, PPS for acidic coal flue gas, Nomex for dry heat, membrane laminates for strict PM limits.
Do you make custom bag sizes?
Yes — every dust filter bag is sewn to your tube sheet diameter and length, with snap-band, flange or ring tops.
Are anti-static filter bags available?
Yes — anti-static felt bags (carbon-scrim / conductive yarn) for explosive dust applications.
What is the difference between singed and membrane finish?
Singed surfaces improve cake release cheaply; PTFE membrane laminates capture fine dust on the surface and serve the strictest emission limits.
