WELDGAS Oxygen FBA In-line
The WELDGAS Oxygen FBA In-line flashback arrestor is a safety device that reliably prevents reverse gas flow and flashbacks in oxy-fuel welding and cutting applications, certified to EN ISO 5175-1 standards.
Overview
A flashback arrestor (FBA) is a critical safety device installed in oxy-fuel setups to prevent flames from traveling back into hoses, regulators, or gas cylinders. The WELDGAS inline model is designed for oxygen use, connecting directly in-line with 3/8" BSP fittings
Key Features
Safety Elements: Equipped with a stainless steel flame arrestor (FA), a temperature-sensitive cut-off valve (TV), a spring-loaded non-return valve (NV), and a filter on the gas inlet
Construction: Inline "barrel type" arrestor with robust stainless steel design for durability and reliable flame extinguishing
Certified Standards: Complies with DIN EN ISO 5175-1, EN 730-1, and is BAM/IBExU certified for safety and quality
Flow Capacities: Maximum free flow rates—oxygen up to 187 m³/h, fuel gases like acetylene up to 68 m³/h
Operational Limits
Single Equipment Use: Only one oxygen device or outlet may be connected to a single FBA
Temperature Range: Maximum ambient/working temperature is 70 °C (158 °F)
Orientation: Can be mounted in any position without affecting performance
Maintenance: Annual inspection of the non-return valve, leak-tightness, and flow capacity is recommended. Replace the dirt filter as needed; servicing should only be performed by a competent person or the manufacturer
Advantages
Prevents reverse flow and formation of explosive gas mixtures.
Extinguishes flashbacks before internal temperatures become unsafe.
Protects hoses, regulators, and cylinders for both single devices and pipeline outlets.
Extends service life of equipment due to inlet filtration and durable construction
In summary, the WELDGAS Oxygen FBA In-line is a high-quality safety device meant for occupational welding and cutting applications, offering comprehensive protection against flashbacks and ensuring compliance with international safety standards while being straightforward to install and maintain.
