Air vent TAV-D

gasnon-condensable gasautomatic

Overview
The Tyco® TAV-D Dry System Air Vent provides oxygen venting in dry pipe fire sprinkler systems. When a fire sprinkler system is continuously supplied with nitrogen from the Tyco® NG-1 Nitrogen Generator, the TAV-D allows oxygen-rich gas to be vented from the system. Over a short period the device reduces oxygen levels to below 2%.

Designed for use with
NG-1 Nitrogen Generators
