MAX developed 400psi High Pressure System and introduced the system in Japanese market in 1994. In 2006 MAX started selling the High Pressure System in North America and has been expanding the market of next-generation fastening systems. Why high pressure? It's simple. Higher air pressure brings higher driving power. The high pressure fastening tools are increadibly powerful yet their tool size is 40% smaller and tool weight is 30% lighter than conventional 100psi models. With the High Pressure System you can not only fasten hard engineer woods but also wood to concrete, wood to steel I beam and steel to concrete.
