The terminal equipment mainly consists of an air-conditioning unit and a fan coil unit. It is different from ordinary household air conditioners. Central air conditioning can be used in large-scale buildings. When the central air conditioner is working, air-conditioning water will be produced, which needs to be filtered.

[0003] Ordinary filter devices have low filtering accuracy and cannot effectively remove impurities and particles in the water, resulting in poor water quality and affecting the operation effect of the central air-conditioning system. Due to the low filtering accuracy, ordinary filter devices are prone to clogging and require frequent cleaning and replacement, which increases maintenance costs. The materials and structures of ordinary filter devices are simple, easy to damage, and have a short service life. Ordinary filter devices have low filtering efficiency and require more energy to maintain the filtering effect. Due to poor filtering effect, ordinary filter devices are prone to cause blockage of pipes, heat exchangers and other components of the central air-conditioning system, affecting the stability of the system.
