Product Description

Superior features add up to superior performanceReliable and durable design To protect against impurities, the 1500 offers stainless steel interconnecting piping and a corrosion resistant intercooler and aftercooler. The 1500 can also run at full load for at least 10 hours with the onboard fuel supply, which can easily be connected to an auxiliary fuel tank.Maximum airend efficiency Extensively field-proven in industrial applications, our two-stage, oil-free airend is the heart of the machine. Each set of rotors is precision-machined in a 20-step manufacturing process and has an UltraCoat™ finish that not only optimizes the rotor profile but resists corrosion. This is essential to minimizing air slippage and maintaining airend efficiency.Power in any climate The 1500 has excellent ambient capabilities, performing in hot climates as well as in temperatures as low as -20 degrees F. The cold-weather protection system gives you the improved response time needed before the machine comes up to temperature and can begin working.Intelligent control Our Intellisys® control system is a comprehensive operational, diagnostic and safety interface. Known for its user-friendly features, this system is built into the 1500 and carefully structured to provide as much or as little information as necessary. It also allows compressor operating parameters to be fine-tuned quickly and easily.Easy to maintain The fluid systems on this compressor are conveniently located and make it easy to maintain fluid levels. Central drain systems are standard for easy servicing.Continuous air delivery With an operating pressure of 150 psi, our 1500 oil-free compressor provides exceptional application flexibility. It’s capable of continuous 1,500 cfm (42.5 m3/min) free air delivery between 60 and 150 psi (4.1 and 10.3 bar), and works well in applications where constant volume is as important as correct pressure. Designed for optimal efficiency, the 1500 also eliminates the need to reduce flow as pressure requirements increase.Environmental awareness The 1500 features a sealed base designed to hold fluid spills, thus preventing potential on-site contamination. In addition, water precipitated from the air stream by the intercooler and aftercooler is collected and routed through our patented condensate burn-off system. This is a significant benefit if you’re operating in humid conditions where condensate disposal can exceed one ton per day — as well as in cold conditions where condensate can freeze in temporary drainage systems.
