Recessed Octagonal Filter Bag fits filtration processes where stable cake formation and liquid passage are required.
Wastewater Treatment: An Octagonal Filter Bag supports sludge dewatering and solid-liquid separation for treatment plants and equipment contractors.
Chemical Processing: Suitable for acidic or alkaline slurry filtration where woven polyester provides mechanical stability.
Metallurgy: A Recessed Filter Press Bag handles mineral and process slurry under press-filter operating conditions.
Pharmaceutical & Sugar Processing: Suitable for filtration equipment suppliers requiring consistent fabric structure and filtration performance.
Industrial Filtration Projects: Supports distributors and system integrators with filter-bag specifications matched to different press equipment.

Stable Air Permeability: 9.68 L/m²·s provides consistent airflow through the filtration fabric during press operation.
Balanced Fabric Density: 209 warp and 126 weft threads per 10 cm create a uniform 6×6 plain-weave structure.
Controlled Fabric Weight: 401 g/m² provides a substantial woven structure while maintaining practical filtration flow.
Moderate Thickness: 0.56 mm supports close fabric contact with the recessed filter-plate structure.
Multifilament Strength: Polyester multifilament construction provides tensile and abrasion resistance during repeated pressing cycles.
Chemical & Temperature Resistance: Polyester fabric withstands acidic, alkaline, low-temperature, and high-temperature filtration conditions.

Recessed Octagonal Filter Bag for Filter Press can be adapted to the filter-plate dimensions, slurry conditions, and operating requirements.
Bag Dimensions: Customize diameter, length, cutting size, and fabric width for different recessed plates.
Sewing Structure: Adjust edge treatment, connection structure, and sewing configuration according to equipment requirements.
Fabric Structure: Modify weaving structure, permeability, pore size, and tensile requirements for different filtration duties.
Material Selection: Polyester can be replaced with PP, PA, PTFE, aramid, or fiberglass when the working conditions require another material.
Functional Treatment: Add anti-static, water/oil-repellent, or PTFE membrane treatment where applicable.
Branding: An Octagonal Filter Bag can include customer logos and brand information on the bag or approved packaging materials.
Development Support: Customer samples, drawings, and operating data can be reviewed; new-project assessment takes 1–3 days.

Recessed Octagonal Filter Bag is produced with material verification, process inspection, and batch filtration testing.
Material Control: Polyester composition and fabric properties are checked before production.
Process Inspection: Weight, thickness, dimensions, tensile strength, permeability, and fabric structure are monitored during production.
Quality Verification: Each batch receives sampling checks for tensile strength, air permeability, temperature resistance, and filtration performance.
Quality Systems: Production follows ISO 9001, ISO 14001, and ISO 45001 systems; RoHS and REACH reports are available.
Lead Time: Samples generally take 7–10 days and regular production 20–30 days, excluding transportation.
Order Support: A Recessed Filter Press Bag can be supplied for small trial orders as well as regular production requirements.

1. What filter press is this Octagonal Filter Bag compatible with?
It is intended for recessed filter press systems using an octagonal bag structure for sludge and slurry separation.

2. What affects the service life of a Recessed Filter Press Bag?
Operating pressure, slurry characteristics, cleaning method, fabric selection, and the frequency of filtration cycles can all affect service life.

3. Can the bag dimensions be matched to existing filter plates?
Yes. Diameter, length, cutting dimensions, and sewing structure can be developed from equipment drawings or samples.

4. What information should be provided for quotation?
Filter-plate dimensions, slurry type, operating temperature, filtration pressure, required permeability, and expected order quantity are useful for specification selection.

5. Can samples be supplied before bulk production?
Yes. Samples can be developed for specification confirmation before regular production.
