Sizing & CFM Calculator

Compressor Sizing & CFM Calculator | Compressive

01. Air Demand

CFM

The sum of all tools and equipment expected to run simultaneously.

15%
Tight (5%) Avg (15%) Aging (25%+)

02. System Pressure

PSI

Calculated at 100 PSI baseline. Adjust for your specific process requirements.

03. Operational Factors

Additional capacity for new equipment in the next 2-3 years.

%

Avoid running at 100% capacity to extend equipment lifespan.

Understanding Your Results

CFM Calculation: The recommended airflow includes your process demand plus margins for system leakage, future expansion, and your specified duty cycle.

Power Estimate: This is based on a standard efficiency of 5.3 CFM per kW. High-efficiency variable speed drives (VSD) may offer lower energy costs.

Pipe Sizing: Based on the velocity of air through a main header. Correct piping is critical to prevent pressure drops.

Next Steps

These figures provide a theoretical baseline for your system. For a precise specification, industrial factors such as ambient altitude, target PSI, and peak surge demand must be considered.
