With over 20 years of precision sheet metal fabrication experience, Lingyufab (Shanghai Lingyu Industrial Co., Ltd.) manufactures high-quality exhaust hoods for commercial kitchens and industrial ventilation systems. We produce custom hoods in stainless steel and galvanized steel, with options for integrated grease filters, fire suppression systems, and custom duct connections. Our capabilities include laser cutting, CNC bending, stamping, welding, and powder coating. As a Mitsubishi Electric certified supplier, we serve food service, manufacturing, chemical, and welding industries worldwide—from 1-piece prototypes to high-volume production.
As a China-based manufacturer located in Shanghai, Lingyufab leverages the region's robust supply chain and skilled workforce to produce high-quality exhaust hoods at competitive prices. We adhere to ISO 9001:2015 quality management system. Our in-house production eliminates outsourcing costs, delivering 15 to 20 percent cost savings to customers. We support 1-piece samples, 100-piece pilot runs, and high-volume mass production with monthly output exceeding 5,000 units.
Our exhaust hoods are engineered to precise specifications.
Lingyufab specializes in producing custom exhaust hood parts including:
Each part is tailored to your specific equipment configuration, space constraints, and ventilation requirements. Our engineering team provides upfront technical support, including airflow analysis, design optimization, and cost-reduction recommendations. We support reverse engineering services. If you have a physical sample without drawings, we can 3D scan, model, and generate production-ready engineering prints. Whether you need a single prototype or thousands of units, we deliver consistent quality with zero MOQ for prototyping stages.
What truly sets Lingyufab apart is our ability to integrate the full spectrum of sheet metal processes, including laser cutting, CNC bending, stamping, welding, and surface treatment, into a seamless manufacturing workflow for exhaust hoods. Rather than outsourcing individual steps to multiple vendors, we manage everything in-house, ensuring tighter quality control, faster lead times, and consistent communication throughout the entire production cycle. With our in-house fastener manufacturing, we can pre-install mounting brackets, filter clips, light fixtures, and duct connection hardware directly onto your hoods, eliminating external sourcing and reducing installation time on your end. The result is a streamlined, cost-effective solution that provides reliable ventilation and air quality control in demanding environments.
Exhaust hoods offer efficient capture and removal of airborne contaminants with several key features. They are constructed from durable stainless steel (304 and 316) or galvanized steel, with options for integrated grease filters for kitchen applications or spark arrestors for industrial use. Standard features include tapered collection channels for draining captured grease, removable filters for easy cleaning, built-in lighting, and customizable duct connections. Surface finishing options include stainless steel, powder coating, or galvanized finishes to resist corrosion and withstand high heat environments. Available with fire suppression system integration, variable speed control, and UL or NSF certification upon request.


Our exhaust hoods are widely deployed in commercial kitchens for capturing grease, smoke, and odors from cooking equipment such as ranges, griddles, fryers, and charbroilers. They are also used in industrial facilities for extracting welding fumes, chemical vapors, and airborne dust at manufacturing workstations. Additional applications include laboratories for fume containment during chemical handling, food processing plants for removing steam and heat, and automotive shops for exhausting exhaust gases and paint fumes. They provide essential air quality control, worker protection, and regulatory compliance in demanding environments. Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 5,000 units.
An exhaust hood is a ventilation device designed to capture and remove airborne contaminants—such as smoke, grease, fumes, heat, steam, and dust—from the air at their source. It is typically mounted above cooking equipment or industrial workstations and connected to a duct system that exhausts contaminated air to the outside. Exhaust hoods are essential for maintaining indoor air quality, ensuring worker and patron safety, and complying with fire and health regulations. They are widely used in commercial kitchens, industrial facilities, laboratories, and automotive shops. Available in wall-mounted, island, proximity, and custom configurations, exhaust hoods can be fabricated from stainless steel or galvanized steel with integrated filters, lighting, and fire suppression systems.
Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 5,000 units.
When designing and fabricating exhaust hoods, consider the following guidelines:
Material thickness typically ranges from 1.0mm to 2.0mm depending on hood size and structural requirements.
Precision is critical for exhaust hoods to ensure proper fit, efficient airflow, and reliable performance. Lingyufab maintains the following accuracy standards:
These standards are maintained through advanced laser cutting, CNC bending, and welding equipment, combined with rigorous in-process inspection and final quality control checks.
Lingyufab implements a comprehensive quality control system for exhaust hoods:
Exhaust hoods and related components can be fabricated into various configurations to suit different applications:
