As a leading manufacturer with over 25 years of expertise, Anping County Boli Hardware Wiremesh Products Factory (established 1998) proudly presents our Industrial Grade Copper Filter Drier Strainer – a critical component designed for refrigeration and air conditioning systems. Crafted from high-purity copper and engineered for maximum moisture and contaminant removal, this filter drier ensures long-lasting system performance and protection against compressor failure. Our annual export value of US$5–10 million and global shipments to North America, Europe, Southeast Asia, and beyond reflect the trust placed in our products by OEMs and aftermarket distributors worldwide.
Product Features & Technical Specifications
- Premium Copper Construction: 99.9% pure copper body and end caps resist corrosion and withstand high pressure – ideal for R22, R410A, R134a, and other common refrigerants.
- High Filtration Efficiency: Stainless steel mesh filter (100–200 mesh) traps solid particles – rust, solder chips, and debris – down to 50 microns, preventing clogging of expansion valves and capillaries.
- Strong Desiccant Core: Filled with molecular sieve (XH-9 or XH-11) and activated alumina for reliable moisture and acid adsorption, protecting the system from freeze-ups and corrosion.
- Wide Working Range: Operates from -40°C to +70°C, with a maximum working pressure of 600 psi (41.4 bar) – suitable for both residential and commercial refrigeration systems.
- Multiple Connection Options: Available in flare, solder, and ODS (ODS=Outside Diameter Solder) types, with sizes ranging from 1/4" to 1-5/8" to fit various system configurations.
- Customizable Capacities: Desiccant volume from 12g to 500g – we can tailor the size and fill according to your specific application requirements.
- Industrial Grade Durability: Double-crimped end caps and brazed joints ensure leak-proof performance even under extreme vibration and thermal cycling.

Frequently Asked Questions (FAQ)
-
Q: What refrigerants are compatible with this filter drier?
A: Our copper filter drier strainer is compatible with most common refrigerants, including R22, R410A, R134a, R404A, R407C, and R32. For specific compatibility with newer blends, please consult our technical team. -
Q: Can I use this filter drier for both refrigerator and air conditioner applications?
A: Yes, it is designed for both. The wide operating temperature range (-40°C to +70°C) and high pressure rating make it suitable for household refrigerators, commercial freezers, split ACs, and industrial chillers. -
Q: What is the difference between flare, solder, and ODS connections?
A: Flare connections use a nut and cone for easy installation without welding; solder connections require brazing for a permanent leak-proof joint; ODS (Outside Diameter Solder) is a solder type specified by the outside diameter of the connection. Choose based on your system’s installation method. -
Q: How do I select the correct size for my system?
A: The size depends on the system’s capacity (tonnage) and the required desiccant volume. A general rule: for systems up to 5 tons, use a 1/4" or 3/8" connection with 16–48g desiccant; for larger systems, consult our sizing chart or contact our sales team for recommendations. -
Q: Do you offer custom packaging or private label?
A: Absolutely. We can customize the packaging with your logo, barcode, and instructions. OEM/ODM orders are welcome. Minimum order quantity (MOQ) for custom packaging is 500 pcs per size. -
Q: What is the lead time for standard orders?
A: For standard sizes and quantities, lead time is 15–20 days after order confirmation. For large or custom orders, please allow 25–30 days. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports. -
Q: How can I ensure the quality before placing a bulk order?
A: We offer free samples (shipping cost may apply) for your evaluation. Production samples and batch inspection reports are available. Our factory performs 100% pressure and leak testing on every unit. -
Q: Is this product suitable for heat pump systems?
A: Yes, it works in both cooling and heating cycles. The bidirectional flow design allows the filter drier to function properly regardless of refrigerant flow direction, making it ideal for reversible heat pumps.
