Dry-Type Backfire Preventer
It is a safety device used to prevent the flame of a medium (such as hydrogen, oxygen, etc.) from spreading outward. It consists of a flame arrester element with numerous fine channels or gaps and a check valve.
Structural Features
The design utilizes the microporous structure of powder metallurgy to dissipate heat and extinguish flames. When a flame passes through the flame arrester element, it is divided into numerous smaller flames. The heat dissipation effect of the element lowers the flame temperature below the ignition point, thereby preventing flame propagation.
A built-in check valve prevents the backflow of combustible gas and avoids sustained combustion.
Operating Temperature: -20 ~ 60 °C
Directional Use Required
