    Before mounting the SmartPurge, it should be configured for the flow range required. To carry out this configuration, choose the appropriate flow rate from Table 1 ML484 | v13 Page Expo Technologies UK Expo Technologies US Expo Technologies China T: +44 (0) 20 8398 8011...
  • Page 15 For internal mounting of the SmartPurge, use an EXPO adaptor plate accessory. Pipe work to and from the air supply unit must be sized to provide adequate airflow with the minimum pressure drop (restrictive pipe fittings should be avoided). The air outlet from the Air Supply Unit should be located or piped to the opposite side of the enclosure to ensure effective purging, unless effective purging can be proved by other means.
  • Page 16 If required, it may be possible to use a custom inlet or outlet flow restrictor in order to achieve satisfactory purge operation. Only standard 8 & 16 hole outlet orifices should be used. SmartPurge allows for custom orifice settings. Consult EXPO for further information.. ML484 | v13...
