DOT 407 Pressure/Vacuum Combination Relief Vent
Girard’s optimal performance combination DOT 407 Pressure Relief Vent and Vacuum Breaker gives
most carriers the option to upgrade their older, less efficient vents. For the majority, upgrading your
venting system will be as simple as taking off the old vent and replacing it with this newest design.

Many customers will find our DOT 407 Pressure/Vacuum Combination Relief Vent to be a more
workable alternative. This is especially true on multi-compartmented trailers needing somewhat limited
vacuum protection. Mechanics and Wash Rack Personnel can easily gain access to common repair areas
in seconds with the quick disassembly feature built into every vent. Please contact our office or your
local Girard distributor for more information.
