From the smallest jobs to the biggest projects, Sullair has the portable diesel air compressor to help contractors get the job done—whether for general construction, winterizing irrigation systems, abrasive blasting, or performing utility work, among other applications.

Many contractors opt for the Sullair 375 Series of portable diesel air compressors. With three units in the family, the compressors deliver 375-425 cfm at 150-200 psi. The 400HH unit is a textbook example of versatility. With the turn of a switch, you can shift from low pressure (150 psi) to high pressure (200 psi).

Just a few of the many features and benefits contractors realize from the Sullair 375 Series include:

Long Runtimes: With improved fuel efficiency for up to 10 hours of runtime, there’s no need to stop midday to refuel. This is a 5-7 percent improvement in fuel consumption compared to legacy units. Sullair portable diesel air compressors are designed to put in a full day’s work, just like you.

Easy Serviceability: Serviceability is key in how we design our equipment. The 375 Series features doors on all four sides of the unit, making it easy to access nearly every nook and cranny. You’ll benefit from easy access to key components including the cooler, aftercooler, battery, battery disconnect, fluid filter, air filter, engine filters, and more. We realize there’s no time for downtime.

Easy Maneuverability: Whether towing to and from the jobsite or storing at your facility, the unit’s compact design means taking up less space and more convenient storage.

An Intuitive Controller: The Sullair controller, which is located on the curbside to help keep the operator safe, features an LCD graphic display showing all key machine operating parameters. Quickly and easily understand the status of your compressor.

Renowned Sullair Air End: At the heart of the compressor is a Sullair air end, continuing the tradition of reliable durability. This is a reputation we’ve built over the past 55 years, meaning you can rely on your compressor, day in and day out.

Value in Versatility: With select units, such as the 400HH, having both high- and low-pressure options helps create more opportunity. You can use the same machine for more applications. For instance, low pressure applications may include construction, while high pressure applications could include well drilling, media blasting, heavy construction, and pipeline/utility/communications line work. You’re able to get more bang for your buck using the same compressor.

The 375 Series is only one option in the Sullair portable air compressor lineup. Sullair offers small, medium, and large portable air compressors, ranging from 185 to 1600 cfm, with multiple engines to give customers additional choices.
