Flame Arrestor Vents safeguard against battery explosions.

Press Release Summary:

Made of hydrophobic Vyon® materials, Flame Arrestor Vents safeguard from potential explosions in lead acid batteries. Sintered porous plastic materials offer chemical compatibility and are resistant to most acids. Creation of flow path, by which gases released through valve element can escape from battery, prevent propagation of potential flames. In addition to preventing sparks from entering battery, vents provide controlled airflow, minimizing risk of acid spillage.

New Vyon® Materials Safeguard from Battery Explosions

A leading developer and supplier of highly efficient flame arrestor vents is set to add new super hydrophobic Vyon® materials to its extensive range.

Porvair Filtration Group has developed cost-effective Vyon® flame arrestor vents for use by battery manufacturers to safeguard from potential explosions in lead acid batteries.

Vyon® sintered porous plastic materials offer excellent chemical compatibility, exceptional strength and are resistant to most acids.

The new super hydrophobic material means that it will not “wet out”, preventing gas venting. Versatile, strong, and efficient, it will also reduce the likelihood of acid spillage.

The potential for explosion within a lead acid battery arises when hydrogen gas created during normal operation reaches a specific hydrogen/oxygen concentration.

However, Porvair’s battery vents have been used to release excess gas from lead acid batteries during operating cycles and prevent flame ingress into the battery.

Porvair believes this has significant safety applications for long-term usage, aiding durability and functionality.

The creation of a flow path, by which gases released through the valve element can escape from the battery, prevent propagation of any potential flames.

In addition to preventing sparks from entering the battery, battery vents provide controlled airflow, and venting, reducing the risk of acid spillage..

Porvair’s consistent manufacturing processes also help to increase the manufacturing efficiency of its customers by providing a uniform surface on both sides of the product.

Porvair – which has supplied the process industry with performance-driven filtration equipment for over 25 years – manufactures in both the UK and USA and has an extensive network of sales offices and distribution channels throughout the world.

The company’s Market Manager Roy Rigby said: “This innovative extension to our range represents a step forward in terms of battery safety and longevity.

“The potential for explosion in lead acid batteries remains present as long as mitigating safeguards are not as effective as they could be.

“However, our cost-effective Vyon® flame arrestor vents prevent gas venting, meaning the risk is significantly reduced. Strong and lightweight Vyon® is resistant to many chemicals making it suitable for many applications.

“We strongly believe that our customers will see the benefits of this product innovation.”
