Rotair's D425K is a powerful yet versatile portable compressor that packs a lot of punch for its size and weight. Built on a platform that includes a JCB 444 TCAE Turbocharged and Intercooled Diesel Engine coupled to a rugged Rotair Direct Drive Air End the D425K can handle a variety of jobs and is a favorite of painting contractors abrasive-blasters and other high-demand users. The D425J's design engineers were sticklers for detail. Some of its features include "Intelligent System" which prevents loaded shutdown and virtually eliminates troublesome "blowback" and a "Minimum Pressure Valve" that prevents abrasive solids from being "back-fed" into the compressor following sandblasting. The D425J is also available in skid mount and can be finished with a special electrostatic paint process to provide more corrosion resistance for offshore applications such as marine agriculture and energy production. Rotair 425's are often found on offshore drilling rigs and fish hatcheries in various salt-water marine bodies around the globe where they are the standard by which all other compressors are judged. Following Rotair tradition the D425K is one of the quietest compressors in its class because Rotair designers engineer in the sound attenuation as opposed to simply gluing it on. Like all Rotair Compressors the D425J is covered by Rotair's industry-leading Five-Year Unlimited Hour Air-End Warranty (see details on website) that requires no special lubricants or specific enrollment. The rugged D425J might be the last compressor in which you will ever need to invest.
