The Westech Series 40 In-Line Deflagration Flame Arrester is designed to provide reliable protection against flame propagation in industrial piping systems handling flammable gases and vapours.
Proper flame arrester selection and placement are critical to preventing flame propagation and ensuring safe operation in systems where ignition sources may be present.
Engineered and manufactured in Canada, the Series 40 quenches deflagration flames before they can travel through process piping, helping protect personnel, equipment, and facilities from potentially catastrophic events.
Unlike active safety systems, the Series 40 operates as a fully passive, self-contained solution, requiring no power, controls, or external components. It can be installed in-line or at the end of a vent line, providing flexibility across oil & gas, chemical, and industrial applications.
Westech supports customers globally with engineering guidance, product selection, and ongoing service to ensure long-term performance and protection.
