G3 G4 Primary Efficiency Activated Carbon Panel Performance Folding Aluminum Alloy Pre Air Filter Cardboard Honeycomb

Pleated carbon filters are an effective way to remove and prevent odors and fumes, and are widely used in air conditioners. The activated carbon materials are folded and supported by paperboard sheets, metal meshes, or other materials to maintain a rigid structure. The pleated carbon filter is then surrounded by a firm frame made of paperboard, foam, aluminum alloy, or galvanized metal. This sturdy frame extends the service life of the pleated carbon filter and allows for easy installation on machines or air conditioners.

The activated carbon bag filter uses a double U-shaped aluminum alloy and a galvanized iron outer frame. The bag is supported by a grille locked into the U-shaped frame, with adjacent grilles pressing the bag tightly. This special construction ensures that the bag is securely locked to prevent it from falling off or getting damaged during handling. All metal edges of the filter are rolled to avoid scratching the filter during installation and replacement, making the operation easy and safe.
