About Sound Levels
Measured in decibels (dB), volume ratings indicate how much noise equipment makes. Some common volume levels include a whisper @ 20 dB, a refrigerator @ 40 dB, a conversation @ 60 dB, and a light machine shop @ 90 dB. OSHA recommends hearing protection for exposure to 80 dB and greater.
Direct-Drive Exhaust Fans
With fewer moving parts than belt-drive fans, these direct-drive exhaust fans require less maintenance. They have a built-in grease pan to collect waste while cooking. Mount these fans directly to your roof with the attached mounting brackets. They meet UL standards for ventilation in residential, commercial, and institutional kitchens.
