Commercial Portable Air Compressors in Houston

Many industrial and manufacturing facilities depend on compressed air to power their tools, whether it be pneumatic drills, spray guns, pumping systems, grinders, sandblasters– anything that requires a source of pressurized air. Air compressors use high-performing electric motors to adjust process air pressure. NiGen’s rotary screw air compressors are currently some of the most popular compressor variants in the industry.

Sullivan D-Series Portable Diesel Compressors

We offer a full range of Sullivan portable air compressors from the D750 to the D1800 series. See the product spec sheets for each of these mobile diesel air compressors below.

How Our Air Compressors Work

Rotary positive-displacement mechanism made up of two meshing helical screws. As the volume inside a closed system (non-vacuum) decreases, the air pressure increases. Air that goes into the system through an inlet valve goes through the two screws, which reduces the volume by rotating at a high speed. This increases the gas pressure, and the compressed air travels through the outlet for use in the operation (or funneled into an air dryer for vapor removal). Depending on the amount of lubrication present in the compression chamber, rotary screw compressors may be oil-flooded or oil-free.
