Share this article


Drawing on extensive experience in the pressure relief field, the BS&B FlameSaf® breather vents offer a dependable, internationally certified and precisely engineered design to prevent excessive overpressure/underpressure and damage of valuable tankage during abnormal operation or as a result of exposure to fire. Designed for the highest standards of precision and safety, these vents use FEP diaphragms to provide tight seals between pallet and seat, which coupled with the 10% overpressure feature result in reliable and accurate response to even minimal changes in pressure. Users benefit from optimized operating conditions close to MAWP (Maximum Allowable Working Pressure) while ensuring operation that safeguard both personnel and environment.
