A continuous flow SYSTEM will continuously flow air through the control PANEL. The flow rate depends on which orifice plate you choose. Applications are small enclosures and analyzers. A leakage compensation system FIRST purges the ENCLOSURE. It then shuts itself down and just tops off for any leakages the enclosure may have. It will maintain a minimum pressure in the enclosure. Continuous flow is more economical to purchase but requires continuous CONSUMPTION of the purge medium. Leakage compensation is more costly up front, but these higher costs can be quickly recovered through purge medium savings.
