Its protective duty is deflagration and its installation arrangement is in-line; establish the hazard and mounting position before selection. The listed size range is DN15–DN500. Specify materials, connections, fluid composition, ignition-source distance and permissible pressure drop for this configuration. Qualification for one flame-arrestor duty must not be assumed to cover another hazard or installation arrangement.
