The legendary P185WDO-T4F 185 CFM Air Compressor from Doosan Portable Power is now powered by a rugged and reliable Doosan D24 engine. The P185WDO maintains Doosan Portable Power’s renowned reliability while incorporating over 50 years of engine experience with the Doosan D24. The improved features and engine on the P185 result in quieter sound emissions, proving that improved power does not have to mean increased noise. This unit also offers enhanced fuel efﬁciency over previous models, keeping more money in your pocket instead of the tank. Doosan is the new manufacturer of the Ingersoll-Rand 185 CFM Air Compressor. These units are made in the same factory as the original Ingersoll Rand Air Compressors.
