Compressed air

🛠️ Energy Reduction from Lowering System Pressure

• Every 2 psi reduction in compressor discharge pressure typically yields approximately 1% energy savings, while a 10% reduction in pressure delivers about 5% energy savings. [des.nh.gov]
• Dropping pressure from 100 psi to 70 psi (a reduction of 30 psi, or 30%) can therefore achieve roughly 15% energy savings.

💨 Decrease in Air Leaks

• Leak losses are proportional to pressure. Lower operating pressure reduces air loss through leaks and fittings. [fluidaired...namics.com], [smeng.com]
• One analysis showed reducing pressure from 100 psi to 80 psi cut leakage flow by about 17%, with additional savings from compressing to a lower pressure. [cagi.org]

🔋 Operational & Maintenance Benefits

• Lowering pressure to the minimum required for tools and equipment helps reduce wear on compressors, piping, and pneumatic systems. [fluidaired...namics.com], [smeng.com]
• Many factories run at 110–125 psi, even though tools often only require 90–100 psi, leading to unnecessary energy waste. [fluidaired...namics.com]
• Reducing pressure by just 2 psi can improve compressor horsepower efficiency by around 1%. [us.kaeser.com], [smeng.com]
