1. Core Advantages

• Precise Adaptation to 200℃ High-Temperature EnvironmentsThe filter media mainly adopts high-temperature resistant glass fiber or synthetic high-temperature fiber. Frames (galvanized steel, aluminum, 304 stainless steel) remain undistorted at 200℃ and can operate continuously for 6-12 months (depending on dust concentration). This avoids the softening and failure of conventional filters (e.g., PP media) at temperatures above 80℃.

 • Smaller Space OccupancyThe non-pleated design uses hot-melt adhesive for separation. With the same filtration area, its thickness is only 1/2 to 2/3 of traditional pleated filters. For example, the 24×24 inch size can be made with a thickness of 1-2 inches, making it suitable for narrow installation spaces such as ceilings and equipment interiors.

• Balanced Filtration Efficiency and Energy ConsumptionThe filtration efficiency is stably maintained at F5-F9 class (per EN 779 standard), with a filtration efficiency of 40%-95% for 0.5-5μm dust particles. The initial resistance is only 40-80Pa (under rated air volume), much lower than that of pleated filters, reducing fan energy consumption by approximately 10%-15%.

• Controllable Maintenance CostsDue to strong high-temperature resistance, frequent shutdowns for replacement are unnecessary. Under normal working conditions, the replacement cycle is 30%-50% longer than that of ordinary medium efficiency filters. Additionally, 304 stainless steel frames are recyclable, reducing the cost of consumable waste.    

2. Typical Application Scenarios Industrial High-Temperature Processing

• High-Temperature Drying for Food/PharmaceuticalsSuitable for tunnel dryers (e.g., biscuit dryers) and vacuum dryers. It prevents dust in the air from contaminating food surfaces and meets food-grade (e.g., FDA) or pharmaceutical-grade (GMP) cleanliness requirements.

 • Painting and Baking for Automotive/Home AppliancesUsed for air intake and circulating air filtration in high-temperature baking ovens (150-200℃). It avoids "particle" defects on paint surfaces caused by dust, ensuring the qualification rate of painted products.

• Plastic/Rubber ThermoformingMatched with the hot air system of injection molding machines and rubber vulcanizing machines. It filters impurities in the air to prevent adhesion to high-temperature plastic/rubber surfaces, which could affect product appearance and strength.  Energy and Environmental Protection Equipment

 • Air Intake for Medium-Low Temperature BoilersSuitable for pre-filtration of air intake in biomass boilers and gas-fired boilers. It traps impurities such as dust and wood chips, preventing ash accumulation inside the boiler that would reduce heat exchange efficiency of heating surfaces and minimizing boiler ash cleaning frequency.

• Sludge Drying TreatmentUsed for pre-filtration of exhaust gas in disc sludge dryers and paddle dryers. It traps dried sludge particles, protecting subsequent bag filters or activated carbon adsorption equipment and extending their service life.  Laboratory and Special Environments

• High-Temperature Aging TestsMatched with high-temperature aging test chambers (e.g., for aging tests of electronic components). It maintains air cleanliness inside the chamber, preventing dust from adhering to test samples and ensuring the accuracy of aging test data.

• Auxiliary for High-Temperature SterilizationUsed for cooling air filtration in pulsating vacuum sterilizers. It prevents dust from outside air from entering after sterilization, avoiding secondary contamination of sterile items and complying with medical cleanliness standards (e.g., YY 0033).
