High Pressure Couplers (HY00000351) MAC2400 MAC5200 MAC700 Makita high pressure compressor technology delivers 400 PSI capacity for the next generation of high pressure nailers. Dual capacity: two universal couplers for conventional nailers (3.6 CFM at 90 PSI) and two couplers for high pressure nailers (2.7 CFM at 300 PSI). Low amp draw reduces incidences of tripped breakers and voltage drop during start-ups. Efficient dual-head (2 stage) pump provides faster recovery time and improved performance. 1,720 RPM enables greater displacement at lower RPM and lower noise.
