This product combines robust copper construction with advanced drying technology, ensuring long-lasting performance and system reliability. Choose Boli for uncompromised quality and global delivery.
Our filter drier strainer is a critical component in any air conditioning or refrigeration system. It actively removes moisture, acids, and solid particles from the refrigerant flow, preventing corrosion, ice formation, and compressor damage. Manufactured from high-purity copper, the shell offers excellent thermal conductivity and mechanical strength. The internal desiccant bed – typically a blend of molecular sieve and activated alumina – provides deep drying capacity while maintaining low pressure drop. Each unit undergoes rigorous quality control to meet international standards, ensuring consistent performance even under extreme operating conditions.
Key Features & Technical Specifications
