Low-Profile Subduct Risers

Key Features:

• IBC and IMC Compliance: The LSR is fully compliant with IBC and IMC standards, ensuring that your exhaust shafts meet all necessary safety and regulatory requirements for bathroom, kitchen, and clothes dryer exhaust systems.
• Versatile Inlet Connections: The LSR is available with female inlet connections in sizes 4, 5, 6, 8, and 10 inches, providing flexibility to suit various applications, including bathroom exhausts and residential kitchen hood exhausts.
• Secure Installation: Each riser is equipped with a 3/8 inch flange, designed to securely attach the riser to the inside wall of the exhaust shaft. This ensures a stable and secure installation, eliminating the risk of loose or disconnected risers.
• Low-Profile Design with Required 22-Inch Rise: The LSR maintains the required 22-inch rise within the exhaust shaft while offering a low-profile design. This makes it an ideal choice for applications where space is limited or where traditional subducts might be impractical.
• Optimized Airflow: Utilizing LSR risers instead of conventional field-erected subducts results in lower air velocities and reduced restriction in the main exhaust shaft. This allows for smaller main shafts, leading to less noise generation and improved overall system efficiency.

Applications:

• Bathroom Exhaust Shafts
• Residential Kitchen Hood Exhausts
• Clothes Dryer Exhaust Shafts
