Trust in BA-BSVLA-S 48” x 48” Single Door LightMAX Smoke Vent - Aluminum, a state-of-the-art solution that prioritizes your building's and occupant's safety. With an innovative design, this single-leaf smoke vent allows a maximum surface area to expel flames, fumes, and gases for unparalleled performance in smoke management, ensuring a safer environment in the event of a fire.  

BA-BSVLA-S' innovative fusible link automatically activates a spring-powered cover for immediate ventilation, and you can count on this model's compression springs to automatically open against wind or loads as high as 10 psf. And with higher-quality insulation, your buildings and your budget will benefit from less consumption. 

Why Invest in BA-BSVLA-S?  

Automated Ventilation: BA-BSVLA-S features a positive releasing latch, activated by a rigorously tested UL-listed fusible link, which melts at temperatures over 165°F. Once the fuse melts, you can count on BA-BSVLA-S' covers to release, expelling flames, fumes, and toxic gases.    

Note: Alternate fusible link temperatures are available; see below.   

Weatherproofed Construction: BA-BSVLA-S has EPDM rubber gaskets permanently adhered to its cover, providing a tight seal while leaving the elements out of your spaces. BA-BSVLA-S has 1" thick PIR insulation within its cover for enhanced thermal resistance (R-6) and reduced energy consumption.
