The Rotair D300K is a "tweener" that can do many jobs that have previously been left to compressors up to twice its size. Producing 300 cfm @ 100 psi thD300K delivers enough air volume and pressure to utilize a #7 nozzle a favorite of industrial painting contractors and can easily run three pneumatic tools simultaneously. So why would anyone want to habitually utilize a larger and thirstier compressor when the rugged Rotair D300K can do so many big jobs with ease? The Rotair D300K comes to life with a Turbocharged Kubota Industrial Diesel Engine and a beefy Direct Drive Air End that rotates at only 2600 rpm. Compare Rotair's air production system to competitive Air-Ends that spin at more than twice that speed putting undue stress on rotor surfaces and bearings. And like all Rotair portables the D300K is covered by a Five-Year Unlimited-Hour Air-End and Drive Coupling Warranty (see details on website) that does not require specific enrollment or the use of expensive supplier-specific lubricants. The Rotair D300K comes standard with "Automatic Intelligence" a system that prevents loaded shutdown and protects the compressor from "blowback" a messy and potentially hazardous condition. So whether you are looking for some additional bulk and a little extra volume or just the right amount of air to fit your job.
