What is the replacement cycle for the air filter element of refrigeration accessory 300047120

The replacement cycle of the air filter element for refrigeration accessory 300047120 needs to be comprehensively judged based on the usage scenario, equipment type, and operating environment. It is generally recommended to replace it every 3000-8000 hours or annually, and specific adjustments need to be made dynamically according to the following factors.
The equipment type and operating load are the core criteria. If the filter element is used at the intake end of the compressor, it is necessary to focus on intercepting hard particles such as metal debris and oxide scale to prevent cylinder wear. In continuous operation refrigeration systems such as cold storage and refrigerated trucks, it is recommended to replace them every 3000-5000 hours; If the equipment is running intermittently or under low load, it can be extended to 6000-8000 hours. For the filter element in the oil system, it is necessary to filter out small particles in the refrigeration oil, and its pollutant content directly affects the service life of the compressor. It is recommended to check it every 2000-4000 hours and replace it immediately when the pressure drop exceeds 0.05MPa.

The operating environment has a significant impact on the replacement cycle. In areas with frequent sandstorms and high dust concentration such as construction sites, the filter element is prone to blockage by large particle impurities, leading to a rapid increase in pressure drop. At this time, it is necessary to shorten the replacement cycle to every 2000-3000 hours. In clean workshops or low-temperature laboratories with excellent air quality, the service life of filter cartridges can be extended to over 8000 hours. In addition, if the system has experienced refrigerant leakage or maintenance, the filter element should be replaced immediately to avoid secondary pollution caused by residual impurities.

Regular monitoring and maintenance can optimize replacement strategies. It is recommended to check the appearance of the filter element every 500 hours. If discoloration, damage, or abnormal pressure drop is found in the filter material, it should be replaced in advance. For filter cartridges compatible with refrigerants such as R12, R22, R410A, etc., it is necessary to ensure that their sealing materials are compatible with the refrigerants to avoid chemical corrosion and leakage. By establishing maintenance records, recording changes in pressure drop, environmental parameters, and replacement times, a replacement cycle
