High-Limit Controls remove grease particles of which size?

High-Limit Controls remove grease particles of which size?

• A. 1 micron
• B. 50 micron
• C. 10+ micron
• D. 100 micron

Answer: (C)

The key idea is how grease-laden air is filtered by kitchen exhaust components: bigger grease droplets are much easier to trap than tiny ones. In practice, devices positioned in the system are designed to capture grease particles that are about 10 microns or larger. Smaller particles tend to stay suspended in the airstream and require more advanced filtration stages to remove. So, grease particles that are 10 microns and larger are what high-limit control-related filtration can effectively remove, making the 10+ micron option the best fit. The smaller 1 micron particles are too fine for this stage, and extremely large droplets (like 50 or 100 microns) are less representative of how grease aerosols behave in typical kitchen exhaust setups, so they’re not the standard benchmark for this requirement.
