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.

Light Duty Direct-Drive Wall-Mount Exhaust Fans with Louvers
These light duty fans are designed for use without duct. They come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Use these fans to draw stagnant and humid air out of a room or area. All have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

Corrosion-Resistant Direct-Drive Wall-Mount Exhaust Fans with Louvers
Rust won't be a problem with the durable plastic housing and louvers on these fans. The fans come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Use these fans to draw stagnant and humid air out of a room or area. All have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

Exterior-Wall-Mount Exhaust Fans
Good when you don't have room to mount an exhaust fan inside your facility, these fans attach to openings in outside walls. Use them to draw stagnant and humid air out of a room or area.
Direct-drive fans have fewer moving parts than belt-drive fans, so they’re easier to maintain. Belt-drive fans are quieter than direct-drive fans. They also last longer because their components can be replaced if damaged.
Fans with an open dripproof motor enclosure should be used in clean, dry, and indoor locations. You can use these fans with or without duct. To use them with duct, you'll need an angle ring (not included). Fans with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments. They mount through the wall, so you'll need to cut a hole on the inside of the wall as well.
Note: Airflow depends on the resistance created by louvers, filters, and ductwork in your system. This resistance, known as static pressure (SP), is measured in inches of water.
Grilles (sold separately) have fixed blades.
Louvers are gravity operated. The blades open when air flows and close when it stops, preventing backdrafts.

High-Capacity Heat Sinks for Oil
For greater cooling capacity and higher flow rates than other heat sinks for oil, these have a large fan. Also known as oil coolers, they're commonly used to cool hydraulic fluid and lubricating oil in cylinders and compressors. Cooling capacity is based on an initial temperature difference of 50° F.
