UK-based Porvair Filtration (Porvair) has developed flame arrestor vents with super hydrophobic Vyon materials to safeguard potential explosions in lead-acid batteries.
According to Porvair, the super hydrophobic material is resistant to most acid, organic chemicals and temperatures up to 110ºC while offering chemical capability. They are designed to reduce the risk of acid spillage and to release excess gas from lead-acid batteries during operating cycles and prevent flame ingress into the battery.
The potential for explosion within a lead-acid battery arises when hydrogen gas created during normal operation reaches a specific hydrogen/oxygen concentration.
The Vyon vents also provide controlled airflow and venting.
“The potential for explosion in lead acid batteries remains present as long as mitigating safeguards are not as effective as they could be,” said Porvair market manager Roy Rigby, “This innovative extension to our range represents a step forward in terms of battery safety and longevity.”
The company said that the vents are for long-term usage and support durability as well as functionality of the battery.
