Application note
Acrylic filter bags are used for selected medium-temperature and humid dust collection conditions where ordinary polyester may not be the best fit.
Best for
- Medium-temperature dust collection
- Humid dust conditions
- Dryer exhaust and selected industrial flue gas
- Applications where polyester may have hydrolysis concerns
Temperature reference
Typical reference around 125-140°C continuous and 150-160°C short peak depending on acrylic type, finish, moisture, and working conditions.
Technical reference
Common weight is often around 500-550 GSM as a typical reference. Top style, bottom construction, sewing thread, finish, moisture content, and cleaning method should be confirmed before quotation.
Main strengths
- Better moisture resistance than ordinary polyester in selected conditions
- Useful for medium-temperature filtration
- Practical option between polyester and high-temperature media
Common applications
- Dryers
- Humid process dust
- Selected industrial flue gas
- Medium-temperature dust collection
Available finishes / options
- Singeing
- Calendering
- Water and oil repellent where applicable
- PTFE membrane where required
Notes before quotation
Confirm bag diameter, bag length, dust type, operating temperature, peak temperature, moisture content, acid/alkali conditions, cleaning method, and photos or drawings if available.
