About Sound Levels
To choose an alarm or speaker that’s loud enough, first determine the decibel (dB) rating of background noise.

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.
About Exhaust Fans
More
Direct-Drive Upblast Roof-Mount Exhaust Fans
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. These exhaust fans draw stagnant and humid air out through your roof and then expel it up and away from the roof surface. All fans have a disconnect switch to turn off the power for servicing.
Fans with a brushless motor have advanced electronic controls that allow them to precisely operate at wide range of speeds, making them more efficient, quieter, and longer lasting than fans with a standard motor.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Direct-Drive Downdraft Roof-Mount Exhaust Fans
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. More economical than upblast roof-mount exhaust fans, these draw stagnant and humid air out through your roof and then direct it back toward the roof. All fans have a disconnect switch to turn off the power for servicing.
Fans with a brushless motor are more efficient than fans with a standard motor. They operate at a wide range of speeds for precise speed control and greater energy savings. They’re also quieter and have a longer lifespan because of their advanced electronic controls.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Motion-Activated Ceiling-Mount Lavatory Exhaust Fans
When a room is occupied, these fans detect the motion and turn on. Set them to turn off anywhere from 30 seconds to 80 minutes after motion is no longer detected. They also sense humidity levels in the room and turn the fan on until the humidity level falls below a set percentage. You can set them to a maximum of 80% relative humidity.

Smoke Removal Blowers
Quickly ventilate smoke, gas, and other fumes by forcing fresh air into your space instead of exhausting air out. These fans improve air quality and manage temperature and moisture levels.
Blowers with an aluminum housing are easy to roll and lift. Blowers with a plastic housing have good corrosion resistance.
