The simplest, most cost-effective approach to reduce corrosion in wet pipe sprinkler systems is to exhaust trapped gas with an ECS Ejector Automatic Vent (PAV-W), also known as a venting system.
Specifically designed for new and existing fire sprinkler systems, the PAV-W offers the lowest clear height for any redundant vent in the industry. The automatic air vent allows gas to escape the system through the device while a float valve seals closed once water reaches the device.
