Discover KnitMesh Technologies’ Flashback Guards

KnitMesh Technologies’ Flashback Guards are a game-changer when it comes to ensuring safety in industrial settings. These innovative guards are designed to be placed in an air stream, allowing for a continuous flow of air while effectively restricting the passage of particles, including sparks, from one part of a plant or process to another.

One of the key benefits of Flashback Guards is their low pressure drop compared to traditional flame arresters, providing an efficient solution without compromising on safety. These guards offer an additional layer of protection for personnel working near equipment that emits incandescent particles, such as burners and oxidizers. Furthermore, they act as a physical barrier, preventing unwanted items like debris, tools, or even animals from infiltrating protected equipment.

Crafted from high-quality knitted wire mesh, typically using stainless steel, KnitMesh Technologies’ Flashback Guards are custom-designed for each specific application, available in modular or single-piece units. This level of customisation ensures ease of installation and retro-fitting, making them a versatile and practical safety solution for various industrial environments.

Flashback Guards are essential in chemical processing facilities where the risk of fire and explosions due to sparks or particles can be high. Flashback Guards provide an additional layer of protection against such hazards.

Power Generation


Whether in coal-fired power plants or renewable energy installations, Flashback Guards help maintain operational safety by minimising the risk of combustion incidents caused by stray particles within equipment.

Manufacturing and Industrial Processes


Various manufacturing plants, including metalworks, glass production, and automotive assemblies, rely on Flashback Guards to safeguard against particle ingress and potential sources of ignition during their operations.



Mines and mineral processing plants benefit from the use of Flashback Guards to protect machinery and personnel from the dangers associated with spark propagation in mining operations.

Water Treatment


Flashback Guards are used in water treatment facilities to protect vital equipment from sparks that may cause fires or compromise water quality, ensuring uninterrupted operation and safety.

Understanding Flashback

Flashback is a phenomenon that occurs when a flame propagates backward through the fuel and air mixture within a combustion system. This can pose serious safety risks, particularly in environments where flammable atmospheres are present. To protect against the potential dangers of flashback, many industries and facilities rely on the use of Flashback Guards, also known as Spark Arresting Panels.

Conventional flame arresters are commonly used for preventing flames from spreading in various applications. However, when it comes to protecting air intakes or fuel/air intakes on larger burners and oxidizers, they may not be the most cost-effective solution. This is where Flashback Guards come into play.

Flashback Guards behave as filters, effectively removing incandescent particles from the process gas stream. They are specifically designed to prevent the backward propagation of flames into flammable atmospheres, reducing the risk of flashback.
