30" x 54" Automatic Smoke Vent - Steel

30” x 54” Automatic Smoke Vent-Steel

If a fire breaks out in your commercial building, a smoke vent can help slow the spread of flames and dissipate the smoke, allowing firefighters time to control the fire. Elevators present a unique point of vulnerability within your building. Our 30” x 54” Automatic Smoke Vent- Steel (BA-NB-20SV) is an excellent choice for smaller spaces, including elevator shafts and stairwells as it uploads stringent standards of the International Building Code (IBC) for hoistway venting.

Our Single-Leaf Acoustical Smoke Vent (BA-NB-20SV) offers enhanced value as a smoke vent with enhanced acoustic properties. Our state-of-the-art smoke vent enhances your utility using higher-quality building materials, mineral wool insulation, innovative construction, and a responsive, automatic mechanism, minimizing potential damage to your buildings. 

Why Choose BA-NB-20SV? 

Ideal for Elevator Shafts: Designed for small spaces, choose BA-NB-20SV for ventilation in your elevators, hoistways, and stairwells in compliance with the code.

Creates a Point of Attack for Firefighters: This single-leaf door localizes flames due to its ventilation properties, allowing firefighters to pinpoint and neutralize fires. 

Built for Streamlined Installations: BA-NB-20SV sports a frame that is easily placed and fitted into its prepared fitting for a simplified installation process. 

Durable Construction: BA-NB-20SV comprises a robust 14-gauge steel construction for greater strength and durability against corrosion and the elements.

Built to Satisfy Building Codes: The application of BA-NB-20SV satisfies International Building Code (IBC 3004.1 & IBC 3004.2) requirements. You can install it directly over your hoistway enclosures and elevator shafts, providing ventilation to both mechanical rooms and smoke in the case of fires.

Automated Unlatching Mechanism: Our innovative Thermolatch mechanism allows an automatic latch release mechanism that is activated using a fusible link, satisfying International Building Code (IBC 910.3.) In an emergency, the fuse will melt at temperatures of about 165 degrees Fahrenheit (74 degrees Celsius,) activating the unit's responsive double-leaf doors.

Stylish Finish: You will receive your BA-NB-20SV in a standard Alkyd base red oxide primer for an elegant and highly aesthetic finish, the perfect accessory to vintage and contemporary roofs.

Vents are critical in the application of elevators, as they provide the necessary ventilation requirements outlined by the International Building Code (IBC 3004.2) with the capability to fit and install the unit above or within the immediate proximity of elevator hoistways. This vent hatch allows for the safe and efficient distribution of toxic gases and smoke fumes.

The mechanism acts as ventilation and limits the lateral spread of fires while protecting against secondary ignitions, contributing to marginal minutes that can potentially save lives. The upward ventilation will minimize the spread of flames to surrounding buildings while creating a point of attack for firefighters when they can access the roof. 

BA-NB-20SV maintains the highest UL standard, with a Class A rating, ensuring peace of mind and safe integration with your building materials. With rigid 4" wool insulation, tested to satisfy UL790 and UL793 requirements, you can install this vent door with complete peace of mind; whether you require a one or two-hour rating, BA-NB-20SV has you covered.

This unit is weatherproofed with complete insulation and gaskets, reducing the potential internal corrosion to its structural integrity. Invest with peace of mind with the addition of the BA-NB-20SV Acoustical Roof Vent for a reliable and effective solution to your smoke ventilation and noise reduction needs.
