310 to 400 Horsepower Air Compressors

Air compressors in the 310 to 400 horsepower (hp) range are designed to supply continuous, high-volume air for large-scale manufacturing, construction, mining, and oil and gas operations.

Rotary screw air compressors are the technology of choice in the 310 to 400 hp range because they provide 100% duty cycles to power large-scale manufacturing processes, pneumatic conveying and material handling equipment, and heavy-duty pneumatic machinery in industrial sectors. Compressors in the 310 to 400 hp range typically offer between 1000 and 2000 cubic feet per minute (CFM) at 100 to 175 pounds per square inch (PSI).

Finding the right air compressor for your application in the 310 to 400 hp range ensures optimal efficiency and performance. As your compressed air partner, JHFOSTER can help you select a 310 to 400 hp air compressor that is cost-effective, reliable, and tailored to your operational requirements.

What are the Applications for 310 to 400 Horsepower Air Compressors?

Most air compressors in the 310 to 400 hp range are rotary screw units, which provide 100% duty cycles and high levels of reliability and efficiency in demanding industrial applications, including:

Industrial cleaning and coating: 310 to 400 hp compressors provide the high levels of airflow needed to operate large nozzles for industrial abrasive blasting, painting, and cleaning.
Large-scale manufacturing operations: 310 to 400 hp compressors supply power for conveyor systems, automation machinery, robotic arms, assembly lines, large presses, clamping devices, and pneumatic tools in large-scale manufacturing plants.
Heavy construction: Compressors in this range can drive multiple heavy-duty jackhammers, construction tools and machinery, and surface prep and finishing equipment.
Mining operations: 310 to 400 hp compressors are used for drilling rigs and to power pneumatic equipment in the mining industry.
Oil and gas sector: Heavy-duty air compressors are used in pipeline cleaning operations and for powering pneumatic instruments and equipment on oil rigs.

What CFM Does a 310 to 400 Horsepower Air Compressor Typically Produce?

Air compressors are often specified solely on horsepower; however, an air compressor should be selected based on horsepower, pressure (PSIG), and flow rate (CFM) specifications. The compressor’s ratings must satisfy the application’s air demand to achieve the highest levels of efficiency and performance.

Here’s a quick run-down of key air compressor selection criteria:

Horsepower: Horsepower, or hp, is a measurement of how much performance the motor can generate.
PSIG: The pressure value, usually seen as a PSIG (pounds per square inch gauge) rating, represents the force of the compressed air and the maximum pressure capacity the unit can safely produce.
CFM: CFM, or cubic feet per minute, is the volume of air the compressor can deliver at the rated pressure (PSIG).

So, the horsepower value represents the air compressor’s output performance at the specified PSIG and CFM rating.

Air compressors in the 310 to 400 hp range provide between 1000 and 2000 CFM at 100 to 175 PSIG.

These ranges are ideal for demanding industrial applications that require high-pressure, continuous air.
