Key Note: All stages comply with international quality management systems (ISO 9001:2015, ISO 16890), and the mesh is tested for dimensional accuracy, tensile strength, pore distribution, and coating adhesion. This ensures every Expanded Metal Mesh for Air Filters batch delivers consistent filtration performance and product longevity.
Applications & Technical Advantages
-
Petrochemical / Refinery Air Intake – High corrosion resistance, withstands acid gases, and prevents pleat collapse under sudden pressure surges.
-
Metallurgy – Thermal-stable mesh maintains rigidity under high-temp processing environments (up to 480°C recommended for SS316).
-
HVAC & Building Air Filtration – Lightweight, open-structure mesh supports pleated or panel filters, offering low pressure drop and superior energy-saving versus traditional expanded mesh.
-
Municipal Water & Wastewater Air Handling – Epoxy-coated mesh resists chemical and moisture damage, ensuring long service life even in corrosive atmospheres.
-
Cleanroom / Medical / Pharma – Meets FDA/ISO cleanroom standards (no particle shedding, inert to disinfectants).
Comparison to Perforated Plate & Woven Mesh:
- Up to 44% lower pressure drop for same filter area.
- 30% higher burst resistance (ISO 16890 test) for matching sheet thickness.
- Flexible mesh patterns possible (diamond, hexagonal, round, etc.).
- Twice the anti-corrosion service life with modern passivation or epoxy coating.
