Advantages of the Sullair 400HDPQ

• Proven rotary screw architecture: The lubricated rotary screw design is engineered for continuous duty, providing smooth, steady airflow with fewer pulsations than piston-style compressors. That means better tool performance, more consistent blast profiles, and less downtime between cycles.
• 400 CFM output: With 400 CFM available, this compressor can support multiple air tools at once, power larger pneumatic equipment, or feed air-hungry processes such as abrasive blasting and industrial cleaning. Crews stay productive without waiting for pressure recovery.
• 150 PSI working pressure: A working pressure of 150 PSI gives you the range needed for common construction, utility, and industrial tasks—from road breaking and chipping to coating removal and plant maintenance. This pressure level also provides versatility across a variety of attachment demands.
• Cummins diesel power: Known for durability, serviceability, and parts availability, Cummins diesel engines are widely supported across North America. That translates to reduced downtime, easier maintenance planning, and long-term operational value.
• Portable, field-ready configuration: The 400HDPQ is built to be towed to the job, parked, and put to work quickly. That mobility supports changing project layouts, short-term rentals to your clients, and multi-site deployment without the complexity of larger stationary systems.
• Sullair brand reliability: Sullair compressors are recognized for robust air ends and well-engineered components. Many buyers specifically seek out Sullair 400-series units because they balance output, fuel economy, and longevity in demanding conditions.
• Cost-effective ownership: As a pre-owned compressor offered at $29,875, this unit delivers professional-grade air capacity at a fraction of the cost of new equipment, while still providing the performance characteristics contractors require.

How These Specs Perform on Real Jobs

On a busy site, compressor performance is measured by how consistently and efficiently it keeps tools and processes running. The Sullair 400HDPQ’s 400 CFM gives foremen the flexibility to power several tools simultaneously or to dedicate the full output to a single high-demand application. At 150 PSI, the pressure range pairs well with industrial chipping hammers, rock drills rated for this class, abrasive blast nozzles designed around 150 PSI profiles, and a wide mix of plant service tools. Because it is a lubricated rotary screw design, the airflow is steady and the machine excels in continuous-duty cycles where piston compressors may cycle and introduce variance into your process.

The Cummins diesel powerplant contributes to day-to-day reliability and easier fleet standardization. Shops that already service Cummins engines will find familiar filters, intervals, and diagnostic patterns, helping to keep scheduled maintenance predictable. For mobile crews, having Cummins under the hood means confidence in starting power, torque delivery, and the ability to keep running in harsh environments where precise air delivery is non-negotiable.

Applications

• Road and bridge work: Support jackhammers, chipping hammers, rock drills, and pavement breakers with stable 150 PSI air to accelerate concrete and asphalt removal.
• Abrasive blasting and surface prep: Feed blast pots and nozzles that require steady 400 CFM airflow for coatings removal, marine maintenance, and steel preparation.
• Industrial maintenance: Provide plant air for shutdowns, turnarounds, and emergency tasks where reliable, continuous airflow is required off the grid.
• Utility and municipal jobs: Power valves, cutters, and tools for water, sewer, and gas projects where portability and quick setup matter.
• General construction: Run multiple air tools on remodels, commercial jobsites, and site services without sacrificing tool performance.
• Quarries and aggregates: Support pneumatic tools for crusher maintenance and plant service tasks away from permanent air systems.

Ownership Value

Contractors and industrial buyers choose the Sullair 400HDPQ for its balance of output, portability, and proven mechanical simplicity. The combination of 400 CFM at 150 PSI with a Cummins diesel power plant delivers the right mix for most mid-to-heavy duty field applications, and the lubricated rotary screw design is made for long runs and steady loads. As a used compressor offered at $29,875, this unit supports lower total cost of ownership compared to new, while remaining a strong asset for revenue-generating work.

Operationally, the benefits show up in reduced downtime and consistent performance. Crews can arrive on site, unhook, start the compressor, and get to work. Fleet managers appreciate the commonality of parts and service for Cummins engines and the industry familiarity with Sullair rotary screw components. Over time, that translates to better scheduling, fewer surprises, and predictable productivity day after day.
