Tier 4 Final air compressor

Sullair unveils its new 400H Tier 4 Final portable air compressor powered by a Cummins QSF3.8 diesel engine.

The unit offers a versatile blend of flow and pressures up to 400 cfm at 150 psi, catering to a wide variety of rental industry customers.

“Sullair continually works with customers to determine how it can improve its products and help meet customers’ most critical needs,” says Nav Sharma, Sullair senior product manager for Rental & Infrastructure. “This particular model is an example of our direct response to customer demand.”

To help guard against downtime on the jobsite, the 400H has a large, 65-gallon fuel tank that allows for uninterrupted operation during a full eight-hour shift. An after-treatment system includes only selective catalytic reduction (SCR)without a diesel particulate filter (DPF), resulting in no engine re-generation, increased ease of use and reduced maintenance.

With an easy-to-use control panel, operator training is reduced, and users are provided an interface to easily access gauges and controls to monitor compressor performance.

The 400H was also designed with serviceability in mind. Its swing doors make it easier to clean coolers, enabling the machine to operate at optimal performance, even in 120F ambient temperatures. Side doors with slam latches allow easy access for service and maintenance; and the 400H’s compact design enables easier towing and maneuverability.

Also allowing for improved maintenance and servicing, Sullair will offer 50-, 250-, and 500-hour service kits tailored to this model. Each service kit includes replacement parts needed for the specified service interval. Having all the parts at hand in a single kit simplifies servicing and the inventory management of parts.

The 400H is part of the Sullair 375 product family, which comes standard with electric brake, low-fuel shutdown, air-filter maintenance indicators and discharge air temperatures, all of which are typically optional on most competitive machines. Featuring the legendary Sullair air end and available in a feature-rich package, the improved model provides the proven reliability customers have come to expect from Sullair.
