The Allpoints 261762 Aluminum Baffle Filter helps capture grease and maintain proper airflow in commercial kitchen ventilation systems.Designed for 20" x 25" hood openings, this filter uses a series of internal baffles that force air to change direction, causing grease particles to separate and collect on smooth metal surfaces. The grease then drains into the hood collection trough, supporting continuous operation. Its aluminum construction with seamless surfaces allows for easy cleaning by soaking or dishwashing. Additionally, it acts as a flame barrier, helping reduce fire risk while improving ventilation efficiency, supporting cleaner air, safer operation, and consistent kitchen performance.
