Item # D40K, Rotair D40K Diesel Portable Compressor



The Rotair D40K produces a solid 40 cfm @ 100 psi in a small, but well-built package. At only 572 pounds, it offers the versatility to be truck mounted or easily moved to the jobsite by forklift or jib. Featuring a liquid-cooled, Kubota Tier 4 Industrial Diesel Engine, the D40K performs like the big boys but has a smaller footprint, and an even smaller thirst for fuel. With an average consumption of 0.53 gallons per hour, fuel costs are almost insignificant when compared to other air compressors. The D40K is solid and quiet, with the same design features of larger Rotair compressors, including a Direct-Drive Air-End, Premium Sound Attenuation System and Spin-On Filters. And, because Rotair understands that you wouldn't buy an air compressor you didn't need, it builds the D40K in a way that it is comfortable in protecting with a Five-Year, Unlimited-Hour Warranty on the Air-End and Drive Coupling (see details on website). Just because the D40K is the smallest diesel compressor in Rotair’s line, it does not mean that it is any less important to either of us.
