8,000 Operating Hours per Year over 5 Years
• Filtration required on lubricated systems to produce “virtually” oil-free air results in
higher pressure drop
• Every 2 psi in pressure drop requires an additional 1% brake horsepower for system
to continue meeting demand = HIGHER ENERGY COSTS
• Ingersoll Rand Class 0 oil-free compressors require minimal filtration
*Note: Cost calculations based on electricity cost of $0.05 per kWh.

Oil-Free Advantage
Total Cost Comparison of Filtration v. Oil-Free
• No makeup lubricant cost because no oil carryover occurs
• Typically lower lubricant/coolant change out costs due to smaller lubricant/coolant system
capacity
• No oil filter replacement costs
• Minimal additional energy costs from filter pressure drop
