The CompAir C42-10 is a portable construction compressor in the DLT 0409-R1 series with 35.0 kW engine power. Its pressure-dependent air delivery is 4.2–5.0 m³/min, with an adjustable gauge-pressure range of 5–10 bar.

This series uses a water-cooled four-cylinder Yanmar diesel engine. It supplies suitably sized pneumatic tools for blowing-out, drilling or blasting work. The chassis and air treatment are selected to suit the application; a generator and additional treatment equipment are optional.
