RIGTOR RDS-185S is a mid-size heavy-duty compressor from the RDS 125-750CFM series. Driven by genuine Isuzu 4JB1 naturally-aspirated diesel engine, it delivers 5.2m³/min (185CFM) airflow at 7 bar. Customers may choose stationary silent cabinet or highway-legal single-axle tow trailer. Its fully-enclosed soundproof canopy meets urban noise requirements. The intelligent digital control panel offers real-time monitoring and full auto-protection against low oil, overheat and overload. Optimized engine-screw matching reduces fuel consumption to 9L/h, ideal for rental fleets. CE & ISO9001 certified, it fits municipal renovation, highway paving, small tunneling and mining. Model datasheet and full-series catalog are available for bulk distributors.
