With 20 years' continuous efforts and innovations, LENGE has developed into one of the largest-scale, highest-specialized and technology-advanced purification equipment manufacturers in China. We introduced the full-automatic ultrasonic welding production line for bag air filter from German, and the automatic production lines for mini-pleat HEPA, deep-pleat air filter, and folded filter cartridge from Korea. Also we introduced the EU standard EN1822 full-automatic testing system for HEPA and the EU standard EN779 and US standard ASHRAE52.2 testing system for pre-filters from German. We established the international standard laboratory for filter cartridges' testing and verification.
