Product Introduction
The stainless steel mesh air filter on this page is a flat, panel-type metal filter. Multiple layers of crimped stainless steel mesh are packed into a rigid metal frame, creating a washable primary filter for HVAC systems, air handling units and exhaust hoods.
Installed at the first stage of filtration, this stainless steel mesh panel captures grease droplets, coarse dust and fibres before they reach coils or higher-efficiency filters. It is especially suitable for kitchens, food processing areas, spray booths and industrial ventilation where air contains oil mist or heavy dust and a robust, reusable metal mesh pre-filter is required.

Key Advantages
1
The multi-layer stainless steel mesh offers a large open area, keeping pressure drop low and helping fans run efficiently even when the filter is installed as the first stage.
2
The crimped mesh structure provides many contact points for catching oil droplets and sticky particles, making this stainless steel mesh primary air filter ideal for greasy air streams.
3
Stainless steel media and, when required, stainless steel frames withstand high temperatures and many corrosive atmospheres better than synthetic or paper filters.
4
he flat panel frame resists vibration and handling damage, so the filter keeps its shape even in large-airflow AHUs or exhaust systems.
Application Scenarios
Our stainless steel mesh air filter is widely used in:
Commercial Kitchens & Food Processing
Used as a primary washable grease filter in canopies, exhaust hoods and make-up air units to capture oil mist and cooking fumes, protecting ducts, fans and downstream filters in restaurants, central kitchens and food factories.
Industrial Ventilation & Process Exhaust
Installed in production workshops, metalworking shops and spray areas where air contains oil smoke, welding fumes or coarse particulate. The stainless steel mesh panel takes the main dust and grease load and helps extend the service life of bag filters or cartridges.
Air Handling Units & Fresh-Air Systems
Mounted in AHU fresh-air or return-air sections as a sturdy metal mesh pre-filter to stop fibres, insects and larger dust before finer filters. Suitable for office buildings, malls, public facilities and general commercial HVAC systems.
High-Temperature & Special Environments
Configured with appropriate stainless steel grades for drying ovens, baking lines and other high-temperature processes where conventional media would deform or burn, while still allowing easy removal and washing.
Marine & Offshore Ventilation
Used on fresh-air intakes for ships, offshore platforms and coastal buildings where air carries salt spray and moisture. The stainless steel mesh and optional stainless frame resist corrosion and can be washed down during routine maintenance.
Compressor, Blower & Equipment Protection
Installed in front of air compressors, large blowers, heat recovery units and energy plant equipment to prevent scale, fibres and coarse dust entering the machinery. The rigid, washable metal mesh design provides reliable protection in continuous-duty operation.
International Exhibitions
Our products have been featured at several international exhibitions, including the 2023 Shanghai International Air & Ventilation Exhibition. At these events, we've highlighted our Stainless Steel Pleated Mesh Primary Air Filter-putting on live demos to show how effectively it handles grease filtration, and sharing real-world examples of its use in kitchens and factories.
These exhibitions have proven to be excellent platforms, allowing us to fully showcase the filter's strong performance and wide range of applications. Many international clients stopped by our booth, diving into details like its service life in high-grease environments, installation adaptability for different systems, and cost advantages over similar products. Some even brought up specific scenarios from their own facilities, discussing how the filter could integrate-clear signs that the product has sparked genuine interest.
Company Profile
We were founded in 1997 and over the years we have accumulated over 15 years of expertise in international trade. We have sold our products to over 50 countries. Our team has over 70 employees, including engineers, production experts and sales specialists, all of whom have many years of experience. Our factory covers an area of over 6,500 square meters and has all the space and supporting facilities needed to produce first-class products.
You will be surprised to know where our filters end up. In electronics factories, they protect sensitive components from dust. Hospitals rely on them to keep the air in operating rooms clean. Food processing plants use them to ensure that there are no contaminants around the products. Even automotive production lines rely on our filters to keep the workspace clean. You will find our products all over China, and we also sell them to many countries around the world.
Production Workshop
Our production workshop has advanced automated lines and precision testing gear-these aren't just fancy tools, but what let us make filters that hit high-quality marks every time. The automated lines handle cutting, assembling, and shaping with consistent precision, way more reliable than manual work. The testing equipment checks things like filtration efficiency and material strength before anything leaves.
But we don't stop there. From picking raw materials-we only work with trusted suppliers meeting strict standards-to packaging finished products for shipment, every step gets a close eye. Inspectors check materials on arrival, monitor production, and do a final review before shipment. It's all to ensure what you get is reliable, stable, and exactly what you need.
