As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our 200 Mesh Filter-drier Screen — a precision-engineered component crafted from 304 stainless steel with a 1/4" female thread and 0.5-inch diameter. This filter screen is designed to deliver reliable filtration in refrigeration and air conditioning systems, effectively trapping contaminants and protecting sensitive components. With over two decades of wire mesh expertise and annual exports exceeding US$5 million, we ensure every screen meets rigorous quality standards for long-lasting performance.
Our filter-drier screen features a 200-mesh weave that provides an optimal balance between flow rate and particle retention, removing debris as small as 74 microns. The 304 stainless steel construction offers excellent corrosion resistance and durability, even in harsh environments with moisture or refrigerants. The 1/4" female thread allows for easy installation onto standard filter-drier housings, while the 0.5-inch diameter fits a wide range of compact systems. Each screen is manufactured with precision to ensure consistent mesh opening and thread fit, reducing the risk of leaks or bypass.
Key Features & Technical Specifications
- High-Quality 304 Stainless Steel: Resists rust, pitting, and chemical attack from refrigerants like R-134a, R-410A, and ammonia.
- 200 Mesh for Fine Filtration: Captures particles including copper shavings, solder flakes, and desiccant dust, safeguarding expansion valves and compressors.
- 1/4" Female Thread (SAE 7/16-20 UNF): Compatible with standard filter-drier inlet/outlet ports; easy to install with a wrench.
- 0.5 Inch (12.7 mm) Outer Diameter: Compact size suitable for small to medium refrigeration circuits and residential HVAC systems.
- Plain Weave Construction: Provides uniform mesh openings and high mechanical strength under pressure differentials.
- Corrosion-Resistant Finish: No additional coatings needed; natural passivation layer protects against oxidation.
- Customizable Options: Available in other mesh sizes (100, 300, 400), diameters (0.25" to 1"), and thread types (male, flare) upon request.

The 200 Mesh Filter-drier Screen offers tangible benefits for HVAC/R technicians and OEMs: reduced system contamination leads to fewer compressor failures and extended equipment life. The fine mesh prevents desiccant fines from traveling downstream, while the robust stainless steel withstands repeated thermal cycling without deformation. Its compact design fits easily into tight spaces, and the female thread eliminates the need for additional adapters in most installations. By using our screen, you can lower maintenance costs and improve system efficiency.
