PneumaForge is a free library of technical calculators for compressed air, pneumatics and industrial vacuum. The tools are designed to solve reproducible calculations from user-entered values, with formulas, units, assumptions and limits shown wherever practical.
What PneumaForge covers
The site includes calculators for cylinders and actuators, valves and orifices, compressed-air piping and distribution, compressors, air receivers, energy and leaks, air quality and drying, industrial vacuum, and technical conversions.
How the calculators work
Calculations run in the browser using values entered by the user and do not require an account. PneumaForge is not intended to replace manufacturer datasheets, selection software, technical standards, inspections or the judgement of a qualified professional.
Transparency principle
Where a tool depends on reference conditions, absolute or gauge pressure, temperature, efficiency, discharge coefficients, losses or other assumptions, the page aims to make those assumptions explicit so the result can be interpreted correctly.
