425h Specifications, Features & Compatibility Guide

The 425H engineering is centered on the 117 kW direct drive configuration, which eliminates belt slippage and improves mechanical efficiency when generating 425 cfm of airflow. Its oil-injected rotary screw pump is designed for continuous duty, meaning the 10.3 bar maximum pressure can be sustained indefinitely as long as the 246 L fuel tank is supplied. The 2000 kg weight is distributed across a towable trailer with anti-vibration mounts to protect the internal engine-to-pump alignment during transport across uneven terrain. By utilizing a 12 m³/min free air delivery rate, the 425H can simultaneously power multiple 90 lb breakers or large-scale sandblasting nozzles. The inclusion of a moisture separator and a pressure relief valve ensures that the high-volume output does not compromise tool longevity or operator safety. Furthermore, the 76 dB(A) acoustic signature is achieved through precise enclosure venting that maintains airflow for the air-cooled system without allowing excessive sound leakage.
