DF-N-16016 Spacer Mesh — Filter Disc Media 8-9mm Thick

1. Product Core Advantages

Open Honeycomb Structure — High-Porosity Filtration Media

The DF-N-16016 features a regular hexagonal open-mesh face that provides an exceptionally high porosity surface for fluid intake. Combined with the fine diagonal-knit base layer, this dual-face construction creates a filtration medium that accepts high flow rates while retaining particulate — the structural basis for efficient filter disc performance.

8-9mm Thick 3D Core — True Depth Filtration

Unlike thin surface-filter fabrics that clog as soon as the face layer fills, the 8-9mm vertical spacer yarn core enables depth filtration — particles are captured throughout the entire thickness of the media rather than on a single surface. This dramatically extends service life between cleanings and allows the filter disc to handle higher contaminant loads.

High-Density 760gsm Construction — Dimensional Stability Under Pressure

At 760±50 grams per square meter, this is a heavy-duty filtration medium engineered to hold its structure under differential pressure. The dense warp-knit interlock resists deformation and compaction when installed in filter housings, maintaining consistent filtration channels and flow characteristics throughout the operating cycle.

Vertical Guide Channels — Uniform Flow Distribution

The spacer yarns run perpendicular between the two face layers, creating millions of parallel micro-channels that direct fluid uniformly through the media. This eliminates the channeling and dead zones that plague non-woven filter felts, ensuring the entire disc area participates in filtration — not just the path of least resistance.

Washable & Reusable — Lower Operating Cost

Constructed from chemically stable synthetic fibers, this filter media is back-flushable and machine-washable, restoring flow capacity for repeated use cycles. For filter disc systems in industrial and agricultural applications, this reusability translates directly into reduced consumable cost versus single-use filter papers and felts.

3. Application Scenarios

Filter Disc Media

The primary application is as the filtering layer in disc-type filter systems — stacked filter discs for water treatment, irrigation filtration, and industrial liquid filtration. The 8-9mm thickness pairs with disc housings to provide depth filtration that protects downstream equipment and irrigation emitters from particulate damage.

Hydraulic & Oil Filtration

In hydraulic oil and lubrication systems, the high-density spacer structure provides reliable particulate retention while the open face maintains flow capacity under pressure. The chemical stability of the synthetic knit resists degradation from oils and hydraulic fluids, extending filter service intervals.

Water Treatment & Pre-Filtration

For raw water pre-treatment, pond filtration, and process water systems, the media captures suspended solids, algae, and organic debris. The back-flushable structure allows filter discs to be cleaned in place — reducing system downtime versus disposable filter cartridges.

Irrigation & Agricultural Filtration

Drip irrigation systems rely on fine filtration to protect emitters from clogging. Filter discs built with this media deliver the depth filtration needed for agricultural water sources — canal water, well water, and recycled water — while the washable media keeps operating costs low for large-scale farming operations.

Air & Gas Filtration

The 3D open structure also serves in air intake and gas filtration applications where low pressure drop and high dust-holding capacity are required. The honeycomb face captures airborne particulates while the air-channel core maintains flow — a combination flat filter media cannot achieve at equivalent thickness.

5. FAQ

Q: What is the minimum order quantity (MOQ)?

A: Standard MOQ is 500 meters per roll. Sample swatches and test discs are available for evaluation at any time. Die-cut disc orders start at 500 units per diameter.

Q: What is the particle retention range of this media?

A: The filtration rating depends on disc configuration and system pressure. As a depth filtration media, it typically retains particles in the coarse-to-medium range (50–300 micron class, configurable via disc stack design). Contact us with your target retention specification and we will provide test data for your application.

Q: Can this media be cleaned and reused?

A: Yes. The 3D spacer structure is back-flushable and machine-washable. Reverse-flow cleaning dislodges captured particles from the depth channels, restoring flow capacity. In irrigation and pre-treatment applications, media cleaned in place has achieved 3–4× the service life of single-use filter media.

Q: Can you supply pre-cut filter discs to fit our housings?

A: Yes. We offer die-cut discs from 50mm to 500mm diameter with clean, sealed edges that resist fraying in filter housings. Edge treatments (heat-sealed or stitched) are available for high-pressure applications. Provide your housing dimensions and we'll match the disc spec.

Q: Is this media resistant to oils and chemicals?

A: The fabric is constructed from chemically stable polyester-based synthetic fibers, providing good resistance to oils, hydraulic fluids, and common industrial chemicals. For aggressive chemical or high-temperature applications, please specify your operating conditions and we will recommend the appropriate fiber grade.
