4, the automatic control system. Automatically adjust the electric field strength, so purification equipment in the long run remains a high purification rate. Green and red lights to show the correct status of their work. 5, security. A well-designed system-wide security, air purifiers principle, pre-filter is opened, high voltage power supply is automatically cut off; high-voltage power supply unit body epoxy designed to tightly closed for safety and reliability 6, stability. Static power supply control system has automatic overcurrent and overvoltage protection devices to ensure stable operation of equipment. When an error occurs operation or long periods of cleaning, the air purifier will automatically stop working. 7, low running costs. ① reduce energy consumption --- improve the cleanliness of return air duct, can save about 12% -18% of the electricity. ② cost savings of air conditioning, cleaning, purification machines, air conditioning systems greatly reduce maintenance costs. And reduces the air conditioning mechanical losses. The proprietary metal filter saves the cost of regular replacement of the filter. 8, easy to install. Directly installed in the central air conditioning return air, air pipes, air-conditioned modular chassis; independent ceiling, ceiling evolution 100 years changed the relationship between the traditional linear electric field, plate-like electric field parallel to the direction of the air flow, with the electric field perpendicular to the direction of the airflow, thereby reducing the electrostatic drive into the distance, effectively shortening the dust collection time, so the purification efficiency is higher; change the original structure of the collecting plate of flat, multi-layer network structure, generated when the air flow through the swirling, greatly enhanced electrostatic chargeability, cleaner effect, and duct resistance has not increased, to save energy role; that is greatly enhanced electrostatic chargeability, turn dust, sterilization, eradicates harmful gases incorporated as one.
