Disposable Automotive Paint Strainer Paper Filter Funnel 125 190 260 Micron

Automotive Paint Filter Funnel with Multiple Micron Options

This disposable paper paint strainer is designed for selected automotive paint-mixing, transfer and spray-gun-filling operations. It combines a formed virgin wood pulp paper cone, monofilament polyester mesh and bonded construction to provide controlled filtration and reliable handling during normal use.

Available Configurations:

Product dimensions, packing quantity and carton dimensions should be added after confirmation with the technical and packaging teams.

Match Micron and Paper Weight to the Application

Filtration grade and paper weight should be evaluated together. A suitable configuration balances filtration fineness, coating flow, cone stiffness, wet handling and the coating manufacturer's process requirements.

These are general selection directions, not universal coating assignments. Confirm the final configuration through coating-manufacturer guidance or controlled compatibility testing.

Material Construction

Paper Cone - Bleached or natural-white virgin wood pulp paper is formed into a stable cone. Available 120 GSM and 140 GSM options allow buyers to select the required balance of material weight, stiffness and handling.

Filter Mesh - Monofilament polyester mesh with uniform openings supports consistent filtration and stable flow during normal paint transfer.

Bonded Construction - The mesh and side seam are bonded to help maintain product integrity during controlled single-use filtration. Adhesive formulation and coating compatibility should be confirmed for the intended application.

Quality Control for Bulk Paint Strainer Supply

For wholesale and OEM procurement, batch consistency is as important as the performance of an individual sample. Defined inspection points help buyers compare samples, approve specifications and monitor repeat orders.

Inspection Points:

1. Appearance - Check for obvious damage, loose adhesive, severe creases and paper debris.
2. Mesh Uniformity - Check for consistent openings without obvious broken threads, distortion or blocked areas.
3. Paper Weight - Verify GSM against the approved product specification.
4. Cone Forming - Check shape consistency and relevant opening dimensions.
5. Bonding - Inspect mesh attachment and side-seam integrity.
6. 500 mL Filling and Shape-Retention Test - Check whether the cone retains its structure under defined internal test conditions.
7. Controlled Thinner-Contact Test - Inspect the paper and bonded areas after exposure under the approved internal test method.
8. Filtration Flow Test - Check for continuous and stable flow under defined test conditions.
9. Cleanliness Inspection - Check filtered liquid for visible fibers, paper debris and adhesive particles.
10. Batch Sampling - Inspect random samples to monitor production consistency.

Test liquid, exposure time, sample quantity, acceptance limits and test environment should be stated in the approved QC specification before they are presented as contractual requirements.

Ten Points Buyers Should Check Before Bulk Purchasing

• Mesh material and opening uniformity
• Filtration-grade accuracy
• Paper GSM consistency
• Paper stiffness and forming quality
• Wet handling strength
• Compatibility with the intended paint and solvent system
• Mesh-to-paper bonding
• Side-seam integrity
• Filtration flow
• Batch-to-batch consistency and cleanliness

A reliable supplier should be able to discuss approved samples, inspection criteria and repeat-order consistency rather than relying only on a visually acceptable reference piece.

One Product Series for Different Filtration Requirements

Three available filtration grades allow buyers to configure the product for different coating viscosities and preparation processes. A smaller micron value indicates a finer opening, but the lowest number is not automatically the best choice. Coating viscosity, pigment or solids content, temperature and required transfer speed can all affect filtration behavior.

Bulk Packaging for Distributors and Wholesalers

Packaging can be configured for wholesale, distribution or private-label requirements. Final carton specifications depend on:

• Funnel dimensions
• Units per inner pack and outer carton
• Individual or bulk packing method
• Printed or neutral carton design
• Labeling and destination-market requirements

Before production, confirm the packing quantity, carton dimensions, gross weight, net weight, barcode or label requirements and shipping-mark format.

OEM Logo Printing and Customized Paint Strainers

OEM options are available for automotive coating distributors, body-shop suppliers, wholesalers and paint-consumable brands.

Available Customization:

• Company or brand logo printing
• Neutral or customized packaging
• Available micron specification
• 120 GSM or 140 GSM paper
• Selected product dimensions, subject to production feasibility
• Customized carton printing and shipping marks

Information Required for OEM Evaluation: Product size + micron rating + paper GSM + order quantity + logo artwork + packing method + destination market. The sales and technical teams can then confirm production feasibility, sample requirements, MOQ, lead time and quotation.

Correct Use for Reliable Filtration

1. Prepare the coating according to the paint manufacturer's mixing instructions.
2. Place the strainer securely over a clean receiving container or spray gun cup.
3. Pour the mixed coating slowly through the polyester mesh.
4. Allow the coating to pass naturally without forcing or scraping the mesh.
5. Transfer or use the filtered coating according to the manufacturer's instructions.
6. Dispose of the strainer after use.

Important:

• Do not stir or scrape paint inside the strainer with hard tools.
• Excessive mechanical force may damage the mesh or bonded area.
• Confirm compatibility before use with unfamiliar paints, reducers or thinners.
• The product is designed for single use and should not be reused.
• Store sealed in a clean, dry environment away from moisture, heat and direct sunlight.
• Publish a shelf-life claim only after it is confirmed in the approved product specification.

Frequently Asked Questions

1. How do I choose the correct micron rating?
Choose according to coating type, viscosity, formulation, required flow and the coating manufacturer's filtration recommendation. The available grades are 125 μm, 190 μm and 260 μm. Conduct controlled compatibility testing when the correct grade is uncertain.

2. What is the difference between 125 μm, 190 μm and 260 μm?
The 125 μm option provides finer filtration, 190 μm is a medium general-purpose grade, and 260 μm has a more open mesh. A finer mesh can capture smaller visible particles but may reduce flow with higher-viscosity coatings.

3. Why does paper weight matter?
Paper weight influences cone stiffness and wet handling. The 140 GSM option uses heavier paper than 120 GSM and may be preferred where greater structural support is required. The correct choice depends on the coating system and handling process.

4. Can the strainer be used with thinner or reducer?
It is intended for selected compatible automotive coating systems. Because solvent formulations vary, buyers should test the specific paint, reducer or thinner combination before bulk use. Any claimed exposure time should follow an approved internal test method.

5. What can cause a paper paint strainer to collapse?
Possible causes include insufficient paper stiffness, excessive liquid load, poor wet strength, weak bonding, unsuitable filtration grade or incompatibility with the solvent system. Product selection and controlled use both affect performance.

6. How can buyers evaluate filtration quality?
Check mesh uniformity, micron accuracy, paper GSM, cone forming, wet handling, bonding, seam integrity, filtration flow and visible cleanliness. Bulk-order approval should use defined samples and agreed inspection criteria.

7. Are different paper weights and mesh grades available?
Yes. Available mesh grades are 125 μm, 190 μm and 260 μm, with 120 GSM and 140 GSM paper options. Final combinations should be confirmed according to production feasibility and the intended application.

8. Do you offer OEM logo printing and customized packaging?
Yes. Logo printing, packaging, selected dimensions, paper weight, micron rating and carton printing can be discussed for qualified OEM orders.

9. What should be included in an approved bulk-order specification?
The specification should define dimensions, paper GSM, mesh material, micron rating, color, printing, units per pack, carton configuration, inspection method and acceptance criteria.

10. Can pre-production samples be supplied?
Sample availability, cost, configuration and shipping terms should be confirmed according to the requested specification and destination.
