Introducing the new DOT407 Pressure/Vacuum
Combination Relief Vent
 

Girard’s optimal performance combination DOT407 Pressure Relief Vent and Vacuum Breaker will give 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 the newest DOT407 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. Best of all this product is available now. Please contact our office or your local Girard distributor for more information.
