The K2 tank was developed by Hyundai Daelotem and has been certified for its excellent performance worldwide and is in operation in Turkuye, Poland. The transmission, a core component, was developed by SNT Dynamics, and we have developed and supplied transmission filters together with SNT Dynamics, and have successfully localized them together with the Korean Army Munitions Company and obtained a certificate of research and development. We have built all the performance test equipment for the K2 tank transmission filter, enabling us to certify the product quality. It has low pressure loss, high filtration efficiency, and durability that does not break even under a pressure of 25kgf/㎠, and it is not damaged even in an environment of -32℃ and 152℃.
