How to Match a Replacement Filter Bag
Replacement Bags for Different Baghouse Types
Pulse-jet filter bags are usually installed over filter cages and cleaned with compressed-air pulses.
Common configurations include:
- Snap band top
- Flange top
- Ring top
- Soft cuff
- Raw edge top
- Disc bottom
- Reinforced bottom
- Wear cuff
- Ground wire
- PTFE membrane construction
Pulse-jet replacement bags must fit the tube sheet and cage correctly. An incorrect snap band size or poor installation may result in dust leakage into the clean-air chamber.
Shaker filter bags are commonly used in older mechanical shaker collectors and usually require woven fabrics or specific attachment structures.
Available configurations may include:
- Loop top
- Hanger top
- Strap top
- Grommet top
- Snap band bottom
- Corded cuff
- Reinforced cuff
- Custom mounting designs.
.
Reverse-air filter bags are commonly used in larger industrial baghouses and may use anti-collapse rings to maintain bag shape during cleaning.
Typical configurations include:
- Strap top
- Loop top
- Cord top
- Grommet top
- Compression band
- Steel cap
- Cuffed bottom
- Beaded cuff
- Anti-collapse rings
Reverse-air bags must be designed around the suspension method, cleaning cycle, bag spacing, and ring configuration.
Replacement Filter Bag Materials
The correct filter media depends on temperature, moisture, gas composition, dust abrasiveness, cleaning method, and emission requirements.
Replacement Filter Bag Materials
| Filtre Ortamı | Temperature Resistance(Continuous / Peak) | Aşınma Direnci | Dimensional Stability | Flex / Fatigue Resistance | Typical Application Conditions | Key Considerations |
|---|---|---|---|---|---|---|
| Polyester | ≤130°C / 150°C | Mükemmel | İyi | Mükemmel | Dry, low- to medium-temperature dust collection | Cost-effective, abrasion resistant, and widely used for general industrial dust collection |
| Akrilik | ≤130°C / 150°C | İyi | İyi | İyi | Humid conditions or mild acidic environments | Good hydrolysis resistance; suitable where polyester may be affected by moisture |
| PPS | ≤160°C / 190°C | İyi | İyi | İyi | Acidic gas, moisture, and chemical environments | Performs well in sulfur-containing gas streams when oxygen levels are controlled |
| Aramid | ≤200°C / 240°C | İyi | İyi | İyi | Dry high-temperature dust collection | Common for asphalt, cement, and thermal processes; not ideal for wet acidic conditions |
| P84 | ≤240°C / 260°C | Orta düzeyde | Mükemmel | İyi | High-temperature fine dust filtration | Excellent dust release and high-temperature stability; abrasion protection may be required |
| PTFE | ≤240°C / 260°C | Orta düzeyde | Mükemmel | Orta düzeyde | Corrosive, humid, or chemically aggressive gas streams | Excellent chemical resistance and moisture resistance; selected for severe operating conditions |
| Fiberglas | ≤260°C / 280°C | Orta düzeyde | Mükemmel | Limited | Very high-temperature dry gas systems | Often used in cement, metallurgy, and power applications; requires careful handling and proper surface treatment |
Surface Treatments and Performance Options
PTFE Membrane
PTFE membrane filter bags support surface filtration and can improve dust release, filtration efficiency, and differential pressure stability.
Water and Oil Repellent Treatment
Water and oil repellent treatments can help reduce moisture penetration and dust adhesion.
Anti-Statik
Anti-static filter bags can help reduce electrostatic buildup in combustible dust environments.
