The K2 tank was developed by Hyundai Drotem and has been certified for its excellent performance worldwide and is in operation in Turkuje, Poland. We have successfully localized the engine's fuel filtration filter, a core component, with the Korean Army Ordnance Company and obtained the R&D certificate. We have built all the performance test equipment for the K2 tank's fuel filtration filter, enabling product quality certification. It has low pressure loss and no breakage even at 5kgf/㎠ pressure resistance, and has no damage even in an environment of -33℃ and 63℃.
