It features curb-side controls to keep operators away from traffic and an intelligent start/stop system that prevents cold starting and blowback, extending the life of the machine. The unit is fully enclosed for protection against the elements and includes an onboard toolbox for convenient storage of hoses and fittings. Whether you opt for the single-axle trailer mount with a pintle hitch or the skid-mounted version, you are protected by an industry-leading 5-year unlimited hour air-end warranty and a 3-year Kohler engine warranty, ensuring your investment remains reliable year after year.

Pro-Tip: To ensure the longest life for your ELGi rotary screw compressor, always allow the machine to run for 3–5 minutes at idle before shutting it down after a heavy workload. This allows the turbocharger to cool down properly and ensures the oil circulates to stabilize internal temperatures, preventing "heat soak" and premature airend wear.
