Product Description
The Welding Copper Filter Drier with Pipe is an essential refrigeration component engineered to filter impurities, absorb moisture, and neutralize acids within refrigeration and air-conditioning systems.
This premium filter drier features a pre-welded copper pipe connection, simplifying installation while ensuring strong sealing and reliable refrigerant flow.
Ideal for use in refrigerators, freezers, cold rooms, air conditioners, and heat
pump systems, it safeguards the compressor and other key parts by maintaining a
clean and dry refrigerant circuit.
Product Features & Advantages
Integrated Copper Pipe Design – Pre-welded copper inlet/outlet pipes allow easy brazing and secure connection, reducing installation time.
Efficient Moisture & Acid Removal – High-performance molecular sieve core effectively absorbs moisture and neutralizes harmful acids to protect the system.
Durable All-Copper Construction – Seamless copper shell offers superior corrosion resistance and long-lasting reliability.
Leak-Proof Sealing – Advanced welding technology provides excellent pressure resistance and prevents refrigerant leakage.
Wide Refrigerant Compatibility – Suitable for R134a, R404A, R22, R410A, R32, R600a, R290, and other common refrigerants.
Compressor Protection – Minimizes contamination and ice formation, extending equipment lifespan and reducing maintenance costs.
Versatile Applications – Perfect for OEM production, system upgrades, and professional maintenance projects.
Installation & Usage Guidelines
Preparation
Ensure the system is evacuated and cleaned before installation.
Verify the correct flow direction, indicated by the arrow on the drier body.
Brazing Process
Use nitrogen during brazing to prevent internal oxidation.
Connect the pre-welded copper pipes to the refrigerant line using standard brazing methods for a secure and leak-free seal.
Final Testing
Perform a pressure leak test after installation.
Always replace the filter drier when opening the system for maintenance or refrigerant replacement to maintain optimal performance.
