Question: 1 / 400

At what angle should grease filters be installed in commercial cooking hoods?

30 degrees

45 degrees

60 degrees

The grease filters should be installed at a 60-degree angle in commercial cooking hoods to optimize their effectiveness in capturing grease and other contaminants from the cooking processes. This angle allows for proper airflow and ensures that grease-laden vapors are efficiently directed toward the filters without causing excessive turbulence. The slope is designed to facilitate drainage of accumulated grease, which helps prevent buildup and maintains the filter's performance over time.

Having the filters at this angle also supports ease of cleaning and maintenance, as the grease can run off effectively rather than pooling or collecting in places that are hard to reach. Ensuring that the filters are installed correctly is crucial for maintaining the overall efficiency and safety of the kitchen ventilation system.
