New Sullair air compressors use electronic spiral valve technology

Sullair has launched its Mid-Range Series of Tier 4 final portable lubricated rotary screw air compressors.

Sullair has launched its Mid-Range Series of Tier 4 final portable lubricated rotary screw air compressors, which the company said were the first of its portable air compressors to incorporate electronic spiral valve technology.


“Electronic spiral valve technology is a gamechanger in our portable air compressors,” said Jerel Cole, Senior Product Manager at Sullair in Michigan City, Ind. “Sullair electronic spiral valve technology helps maximize fuel efficiency and extend runtimes by matching air supply to demand. It allows an operator to quickly and easily input the exact pressure they want, anywhere between 100 or 200 psi, and the machine calibrates to give maximum flow at that pressure. It gives users all the air they want, at the pressure they need.”

The company said the Mid-Range Series is designed for flexibility and efficiency, with the 800HH/900H model delivering 800 to 900 cfm at 150 to 200 psi, and the 920H/1100 model delivering 920 to 1100 cfm at 100 to 150 psi.

The new portable units can be ordered with a Caterpillar 7.1L or a Perkins 1206J diesel engine rated 302 hp; the 7.1L diesel engine replaces the previous generation’s 9 L powerplant. The smaller sized engine reduces the compressor’s overall weight, making towing and maneuverability easier and minimizing impacts to the environment.


The company said flexibility of the Sullair Mid-Range Series covers the jobs of up to nine compressors. Applications include pipeline work, construction, abrasive blasting, fiber optics installation, shipyards and more.

“Flexibility is at the center of how and why we developed the new Mid-Range Series,” said Cole. “For rental companies, this means one compressor covers a wide range of applications — giving rental companies maximum ROI and higher utilization rates. Construction companies also benefit from a reduction in the number and types of compressors they need to own. The Mid-Range Series provides different pressure/flow options at different times, eliminating the need to rotate compressors in and out of a jobsite. Instead, one unit solves many of their needs.”

The Mid-Range Series gets a 7 in. Sullair Touch Screen (STS) controller for easy control at the touch of a finger – even with gloves on – and multiple service doors with push-to-close latches. These provide easy access to all service components to maximize uptime and help increase worker safety. Users also have the option of adding Airlinx, which provides telematics and remote monitoring capabilities.
