Self-powered — no mains supply needed on site, just fuel and a level standing area. The 900 cfm Diesel Air Compressor is built for continuous industrial duty. It runs on a direct-coupled air end with no belts to re-tension, and it is delivered as a complete package — airend, motor, cooler, separator and controller on one base frame — so on-site work is limited to power, piping and a drain.
Industrial diesel engine with a mechanical governor, matched to the airend so the unit holds pressure across the working range. Serviced through a wide-opening canopy door.
A single-stage oil-injected rotary screw airend with asymmetric rotors machined and lapped as a matched pair. Large-diameter rotors run at low speed for a long bearing life and a stable specific power figure.
Combined controller and protection panel: start/stop, safety shutdowns for temperature and pressure, and hour meters for service planning.
Wet separator tank with a two-stage element that brings carry-over down to a few parts per million. The vertical design gives the oil time to settle before the next cycle.
Twin heavy-duty intake filters for high-dust sites, sized so both elements can be changed without removing the canopy.
Spin-on full-flow oil filter with a large filtration area. It protects the airend bearings from wear particles and keeps the oil service interval predictable.

Every unit ships with an 18-month warranty on the air end and 12 months on the rest of the machine, counted from commissioning or 24 months from shipment, whichever comes first.
Each machine is run on the test bench and the delivered flow, working pressure, current draw and noise level are recorded against the datasheet before it is crated.
Installation drawings, piping diagrams and a commissioning checklist are supplied with the machine, with remote engineering support during start-up.
Airends, motors, controllers, filters, separators and cooler assemblies are held in our own warehouse, so service parts are not tied to a production run.
No. The unit is driven by its own diesel engine, so it only needs fuel and a level standing area. That is the reason these machines are used on road, quarry and pipeline work.
The fuel tank capacity and the engine load determine the running time; both are in the specification table. For long shifts we recommend the skid or portable variant with the larger tank.
The portable variant comes on a towable chassis. Check the local road regulations for the towing speed and the brake requirements before moving it between sites.
Optional engine pre-heat and a larger battery are available for cold-start conditions — tell us the lowest expected ambient temperature when you order.
