Average protective gas consumption during PRESSURIZATION at a 0.10 inch (2.5mm) enclosure pressure should fall somewhere between 0.1 to 3.5 SCFH per cubic foot (2.83 to 99.11 l/hr) of enclosure VOLUME. However, use will depend on the protected enclosure’s integrity and normal pressure setting. Use is also dependent on the quantity and size of covers and doors as well as devices which penetrate the surface. Advanced forms of protection such as cooling or DILUTION may require continuous flow RATES of 30 to 100 SCFH (849.38 to 2831.26 l/m). Purging requires a much higher flow rate than pressurization, but only for a short PERIOD of time.
