The largest volume producer in the Rotair line, 900 cfm at 100 psi, it is the compressor of choice for running large air tools, specialty pneumatic products, as well as large production jobs, shares a platform with the D800HC, it is a rugged and efficient performer that offers a high level of versatility, unparalleled accessibility through wide doors and a rugged chassis that sometimes seems indestructible.

If standard pressure and big delivery volume fits your needs, the D900HC is worthy of your careful consideration. Pumping out 900 cfm at 100 psi, the Rotair D900C is your top choice for Plant and Process Air, Refinery and Petrochemical Turn-Around work or Industrial Painting. But, this is a versatile machine that can do almost anything it is called upon to do within the realm of standard pressure air delivery. In fact, there are few jobsites that would not benefit from the presence of this reliable and flexible profit producer.

But, just because a diesel air compressor delivers high volume, that does not give it a license to pollute the environment with particulate matter, excessive greenhouse gases or noise. Therefore, Rotair’s engineers have designed the D900C to provide leading-edge performance while being as responsible to the planet, and the humans who work on it, as it can possibly be.
