A flashback preventer with a cylindrical flame trap (8, 8', 21) which is installed in a wall (6, 6'), separating an at-risk region (13) from an external region (15), and has a cross-sectional surface area containing a multiplicity of throughflow gaps and a height determining the length of the throughflow gaps and an underside (9) directed towards the at-risk region (13), and an upper side (16) directed towards the external region (15), can be formed with a low mass and high energy-dissipation efficiency in that the flame trap (8, 8', 21) is inserted into an opening (7, 7') in the wall (6, 6'), said opening corresponding to the cross-sectional surface areas of the flame trap (8, 8', 21), and has at least a fifth of its height projecting beyond the wall (6, 6') into the external region (15). |
