DOT407 JETVENT WELDIN 30#
Girard’s Special Low Profile “Weld-In” (LW) Series DOT 407 Vent combines an ultra-low profile, light-weight design with high flow rates to meet the most
demanding needs of virtually any tank. See the table below for specific flow rates. The LW Vent welds directly to your manway thus avoiding expensive hot-work to the shell of your tank, and is low enough to be “retro-fitted” to most any tank without having to alter the overturn protection.
