Pre-filtration of air-conditioning system, pre-filtration of high-efficiency filtration, pre-filtration of air compressor. The design of the filter itself has also made significant progress, the most important of which is the removal of the partition, that is, the development of non-separator filter. The barrier-free filter eliminates the risk of damage to the filter media by the separator, and effectively increases the filtration area, improves filtration efficiency, and reduces airflow resistance, resulting in reduced energy consumption. In addition, the air filter in high temperature, corrosion-resistant and waterproof, anti-bacterial, also made great progress to meet some special needs.
