Bags - Dimensions, Retention and Materials for Filter Bags
HD Process supplies top entry filter bags in a range of sizes, materials and micron ratings for industrial liquid filtration. Our filter bags are designed for use with standard bag filter housings, including compatible GAF, Eaton and Sefar configurations.
Manufactured using welded or stitched seams, the bags provide reliable particle retention while minimising media migration and bypass. Customised filter bags are also available for specific filtration requirements.
Filter Bag Materials and Micron Ratings
Our range includes nylon mesh and felt filter bags with different particle retention ratings:
- Nylon mesh bags: 15-1,500 µm (1.5 mm)
- Felt filter bags: 1-600 µm
- Available sizes: 1, 2, 3 and 4
- Compatibility: Options interchangeable with common GAF, Eaton and Sefar bag filter housings.
Filter Bag Sizes and Dimensions
- Size 1: 170 mm diameter × 400 mm length
- Size 2: 170 mm diameter × 800 mm length
- Size 3: 100 mm diameter × 200 mm length
- Size 4: 100 mm diameter × 350 mm length
Approximate filtration areas and internal volumes for standard bag sizes:
- Size 1: 0.2 m² filtration area and 8 L internal volume
- Size 2: 0.4 m² filtration area and 17 L internal volume
These volumes are indicative and may be reduced when a filter torpedo is installed. Supporting filter baskets are available for single-bag, double-bag and basket-only configurations. Mesh-type baskets typically provide more than 50% open area.
