High-Rise Exhaust, Laundry Ventilation, and Pressurization Applications

LF Systems products are identified for use in:

• Commercial laundry facilities
• Dryer exhaust applications
• High-rise buildings
• Stairwell smoke-control and pressurization applications
• Elevator hoistway pressurization applications
• General exhaust systems
• General supply air systems

Stairwell Pressurization, Exhaust Ventilation, and Pressure-Control Applications

LF Systems products may be used when a project requires:

• Positive stairwell pressure during fire events
• Multi-zone stairwell pressurization in taller buildings
• Positive pressure within elevator shafts and hoistways
• Commercial laundry exhaust ventilation
• High-rise exhaust ventilation
• Supply air and make-up air systems
• Constant-pressure control in duct systems and, Control of multiple exhaust shafts through supported controller configurations
• Smoke-control-related fan applications

These use cases combine fans, controls, shafts, and pressure-management components to support the identified building applications. These applications involve building systems where airflow management, exhaust removal, pressure control, and air supply distribution are part of the project requirements.

Why Work With LONG

LONG Building Technologies supports commercial and industrial facilities through engineering support, system integration, lifecycle service, and long-term building system support.

When LF Systems products are selected for a project, LONG works with building owners, consulting engineers, contractors, and facility teams to help evaluate application requirements and coordinate HVAC system integration. LONG’s role is to support the application and ongoing operation of building systems rather than serve solely as an equipment supplier.
