Highly Efficient, Cost Effective Flame Arrestors from Porvair Filtration

Porvair Filtration Group is a leading developer and supplier of highly efficient, cost effective Vyon flame arrestor vents for use by battery manufacturers to safeguard from potential explosions in lead acid batteries.

The potential for explosion within a lead acid battery arises when hydrogen gas created during normal operation reaches a specific hydrogen/oxygen concentration. Traditionally ceramic battery vents have been used to vent excess gas from lead acid batteries during operating cycles and prevent flame ingress into the battery. However these have several disadvantages including poor handling during automated assembly processes and a relatively high cost of manufacture.

Cost effective Vyon® flame arrestor vents for use by battery manufacture from Porvair Filtration.

Vyon battery flame arrestors, manufactured to suit individual requirements, offer an affordable alternative with additional benefits. The unique structure of Porvair's Vyon materials provides a tortuous path structure to prevent sparks propagating back into the battery, thereby preventing risk of explosion and as the materials also act as filters they protect the electrolyte in the battery from contamination. The hydrophobic properties of the material means the pores in Vyon do not wet out thereby allowing explosive gases to easily vent from the battery.

Porvair's porous Vyon materials also offer greater flexibility during the ever more demanding environment of automated battery assembly. Manufactured from both sintered polyethylene and polypropylene allows the Vyon vent to be secured into the battery by a wide range of industry standard ultrasonic welding techniques. This ease of assembly when combined with cost effective vent manufacture makes Vyon an ideal choice for all lead acid battery vent applications.
