Material: grade flameretardant nonwoven fabric for durable filtration and safety in suction systems. Function: Soot filter designed to capture oilcontaining stains drawn into the suction line, helping keep the system cleaner and protecting downstream components. Convenience and maintenance: Replacing the filter regularly is quick and reduces maintenance downtime. Sanitation: Reduces oily residues where bacteria may breed, contributing to a cleaner and more hygienic system. Compatibility and performance: Designed to fit standard suction systems with compatible filter sizes. Check dimensions for proper fit. Effective filtration of oilcontaining soot helps maintain suction efficiency and protect equipment. Replacement guidance: at the recommended intervals to maintain filtration performance and system cleanliness. Use scenarios: In commercial kitchens or cafe kitchens with range hoods, to filter oilbased soot from cooking and help keep ducts cleaner. In workshop vacuums or machines using lubricants and metalworking fluids, to trap oilladen residues and prevent clogging. In automotive service bays or industrial suction systems where oilcontaminated particulates are present, to protect fans and downstream filters.
