Compressed-air calculator
Sizing an air compressor
A compressor does not draw the same air everywhere: the site’s altitude, temperature and humidity reduce the air mass actually available at the intake.
This calculator translates your need into the ACFM capacity required at actual site conditions — the step that keeps a purchase from being undersized.
Compressor sizing
Required ACFM capacity for site altitude, temperature and humidity.
Required capacity — Scenario 1
- ACFM (min conditions)
- —ACFM
- ACFM (max conditions)
- —ACFM
To calculate, still needed: the demand flow, the min and max temperatures.
CAGI / ISO 1217 correction (Annex C). Recommended = worst case (max conditions).
Required capacity — Scenario 2
- ACFM (min conditions)
- —ACFM
- ACFM (max conditions)
- —ACFM
To calculate, still needed: the demand flow, the min and max temperatures.
CAGI / ISO 1217 correction (Annex C). Recommended = worst case (max conditions).
