HVAC Filter Frame Materials
1.Cardboard / Paperboard Frame
Low cost, lightweight, and recyclable. Moisture-resistant coatings improve durability in damp conditions. Primarily disposable, ideal for residential HVAC systems and light commercial applications in standard dry environments.
2.Aluminum Frame
Lightweight, corrosion-resistant, and high in structural strength. Reusable for repeated filter changes. Well-suited for commercial buildings, cleanrooms, humid environments, and systems requiring frequent maintenance.
3.Galvanized Steel Frame
Offers excellent mechanical strength and resistance to deformation under high air pressure, with reliable rust protection. Used in industrial ventilation systems, large-scale commercial HVAC, and high-air-pressure applications.
4.Stainless Steel Frame (304/316)
Features superior resistance to acid and alkali corrosion, high temperature tolerance, and an extremely long service life. Applied in chemical processing, pharmaceutical, and food and beverage industries, as well as other harsh operating environments.
5.Plastic Frame (PP/ABS/PVC)
Moisture-resistant, corrosion-proof, and non-conductive, with customizable sizes and cost-effectiveness. Suitable for residential/light commercial HVAC, pool ventilation systems, and weight-sensitive equipment.
6.Wooden Frame
Eliminates metal contamination risks and allows for custom large dimensions. Used in cleanrooms, laboratories, and special environments where metallic components must be avoided.
7.Composite Frame (Paper + Metal/Plastic)
Combines the lightweight nature of cardboard with the structural strength of metal or plastic. Ideal for mid-to-high-end commercial HVAC systems seeking a balance of performance and cost.
