Technical Support

When selecting a dry filter, you need to consider the following factors: refrigerant type, working pressure, working temperature, flow requirements, and system cleanliness requirements. Our technical team can provide professional selection suggestions based on your specific situation.

The service life of a dry filter depends on factors such as system cleanliness, refrigerant quality, and operating conditions. Generally, under normal use, the service life of a dry filter is 1-2 years. When the system experiences decreased cooling effect, abnormal pressure, etc., the dry filter should be replaced in time.

When installing a dry filter, the following points should be noted: 1. Ensure the system is emptied and cleaned; 2. Install according to the direction indicated by the arrow to ensure the correct refrigerant flow direction; 3. Ensure tight connections to avoid leakage; 4. After installation, system leak detection and vacuuming should be performed.

You should consider replacing the dry filter when the following situations occur: 1. The system's cooling effect decreases significantly; 2. The pressure difference before and after the dry filter exceeds 0.5bar; 3. The dry filter changes color or frosts; 4. The system has experienced refrigerant leakage or major components such as compressors have been replaced.
