At Anping County Boli Hardware Wiremesh Products Factory (established in 1998), we specialize in precision-engineered wire mesh components for demanding environments. Our Epoxy Resin Support Mesh Inside Air Filter Element is specifically designed for pharmaceutical cleanroom HVAC units, where air purity and system reliability are critical. This inner mesh provides robust structural support to filter media while maintaining ultra-low particle shedding, ensuring your cleanroom meets strict GMP and ISO classifications. With annual exports exceeding US$5 million and a global footprint spanning North America, Europe, and Asia, we deliver consistent quality backed by decades of manufacturing expertise.
Our epoxy resin coating is applied through a specialized process that bonds the resin to the stainless steel wire, creating a smooth, non-porous surface. This eliminates the risk of fiber migration or corrosion that could contaminate your cleanroom air. The mesh is typically placed inside multi-stage filter cartridges or panel filters, acting as a rigid spacer that prevents filter media collapse under high airflow or pressure differentials. Customers benefit from extended filter life, reduced maintenance frequency, and stable pressure drop across the HVAC system.
Key Features & Technical Specifications
- Superior Corrosion Resistance: Epoxy resin coating protects against moisture, chemicals, and cleaning agents commonly used in pharmaceutical facilities.
- Low Outgassing & Particle Shedding: The coated surface minimizes volatile organic compounds (VOCs) and dust generation, critical for cleanroom environments.
- High Mechanical Strength: Stainless steel wire core provides excellent tensile strength, preventing deformation under high-velocity airflow.
- Customizable Mesh Configurations: Available in mesh sizes from 10 to 200 mesh, with wire diameters from 0.1mm to 1.0mm, to match specific filter media and airflow requirements.
- Consistent Open Area: Precision weaving ensures uniform open area for optimal air distribution and minimal pressure drop.
- Easy Integration: Can be supplied as rolls, sheets, or pre-cut shapes to fit any filter element design.
| Parameter | Standard Range | Custom Options |
|---|---|---|
| Mesh Count (per inch) | 10 – 200 | Up to 400 mesh upon request |
| Wire Diameter (mm) | 0.1 – 1.0 | 0.05 – 1.5 mm available |
| Open Area (%) | 30% – 70% | Tailored to air flow needs |
| Curing Temperature | 150°C – 200°C | Adjustable per resin type |
| Coating Thickness (μm) | 20 – 50 | Up to 100 μm for high-corrosion environments |
Our manufacturing process includes strict quality control checks at every stage: raw material inspection, weaving, coating, curing, and final dimensional verification. Each batch is tested for adhesion strength, chemical resistance, and particle cleanliness. We also offer optional third-party testing for compliance with specific cleanroom standards if required.
Benefits for Your Cleanroom HVAC System
- Enhanced Air Quality: The epoxy resin support mesh prevents filter media from shedding fibers, keeping the supply air free of contaminants.
- Reduced Energy Costs: By maintaining a stable pressure drop, the mesh helps HVAC fans operate more efficiently, saving energy over the filter’s lifetime.
- Longer Filter Life: The rigid support distributes airflow evenly, preventing premature clogging and extending the replacement interval.
- Compliance with Regulations: Our mesh supports filter elements that meet EU GMP, FDA, and WHO guidelines for pharmaceutical cleanrooms.
- Simple Installation: Pre-cut to your exact filter dimensions, the mesh slides into filter frames without modification.

Frequently Asked Questions
Q1: What is the purpose of the epoxy resin support mesh inside a cleanroom air filter element?
The mesh provides structural reinforcement to the filter media, preventing it from collapsing under high airflow or pressure. The epoxy coating minimizes particle shedding and corrosion, which is essential for maintaining cleanroom air purity.
Q2: Can the mesh size be customized to fit different filter designs?
Yes, we offer mesh sizes from 10 to 200 mesh as standard, and can produce up to 400 mesh on request. We also cut the mesh to your exact dimensions (length, width, and shape) to match any filter frame.
Q3: Is the epoxy resin coating food-grade or suitable for pharmaceutical use?
The epoxy resin we use is formulated for low outgassing and high chemical resistance, making it suitable for pharmaceutical cleanroom environments. If you require specific FDA or USP Class VI compliance, please inform us so we can select the appropriate coating.
Q4: How does the epoxy coating affect the pressure drop across the filter?
The smooth coating reduces surface roughness, which can actually lower the initial pressure drop compared to uncoated mesh. The open area remains consistent, so the impact on airflow is minimal and beneficial.
Q5: What is the maximum temperature the mesh can withstand?
Our standard epoxy resin support mesh can operate continuously at temperatures up to 120°C. For higher temperature applications, we offer alternative coatings (e.g., PTFE or silicone) that can withstand up to 250°C.
Q6: Do you offer samples for testing before bulk order?
Yes, we provide free samples (excluding shipping) for customer evaluation. Please contact us with your required mesh size, dimensions, and quantity. Samples are typically dispatched within 3-5 working days.
Q7: How long is the lead time for production orders?
For standard mesh sizes and quantities, production takes 10-15 working days. Custom orders (special dimensions or coatings) may require 15-25 working days, depending on complexity. We can expedite urgent orders upon request.
Q8: What ports do you ship from, and do you handle export documentation?
We ship from Tianjin, Qingdao, Shanghai, and Foshan ports. We handle all export documentation including bill of lading, packing list, and commercial invoice. We can also arrange shipping terms (FOB, CIF, etc.) as per your preference.
