Flat Envelope Dust Filter Bags for Tobacco Factory Dust Collection

Flat Envelope Dust Filter Bags for Tobacco Factory Dust Collection

Tobacco factories need dust collection systems for processing, conveying, cutting, blending and packaging areas. Flat envelope dust filter bags are used in some dust collectors where the collector design requires a flat bag shape instead of a round bag. These bags help capture fine tobacco dust and keep airflow stable through the system.

Because tobacco dust can be fine and light, filtration stability and sealing quality are important. The bag must fit the collector frame correctly, hold its shape during cleaning and release dust without causing excessive pressure drop.

Important Design Details

• Custom dimensions: flat envelope bags must match the collector structure.
• Strong seams: repeated airflow and cleaning can stress the edges.
• Suitable media: choose media based on dust load, temperature and cleaning method.
• Good sealing: bypass dust can reduce filtration performance.
• Stable dust release: helps keep pressure drop under control.

RFQ Information to Prepare

Send the flat bag dimensions, media type, frame or support details, dust collector model, quantity, photos of the old bag and any current problem such as leakage, wear or high resistance. A drawing is especially helpful for custom flat envelope bags.
