About Sound Levels

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

About Exhaust Fans

About Air Conditioner Cooling Capacity

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.

DC Equipment-Cooling Fans

Running on 48V DC power or lower, these compact fans fit inside electronics and other small, heat-sensitive equipment to keep things cool. They're also known as muffin fans. Some meet American and Canadian safety standards.

Fans with ball bearings generate less heat as they run, so they have a longer life than fans with sleeve bearings.

Fans with sleeve bearings are good for less demanding applications, such as cooling prototypes or parts that aren’t used often.

Fans with quick-disconnect (QD) terminals are compatible with quick-disconnect power cords.

DC Wet-Location Equipment-Cooling Fans

Operate these fans with a DC power source. Also known as muffin fans, they keep heat-sensitive equipment such as electronic components cool. All have ball bearings to lower the heat that is generated from the fans for a longer service life.

High-Pressure Washdown DC Equipment-Cooling Fans

Keep electronics from overheating in places that must be sanitized often. These DC-powered fans are rated IP69K, meaning you won’t damage them with harsh jets of water and they block out dust. For a long life, all have ball bearings that reduce friction and heat as they operate. Also called muffin fans.

Submersible DC Equipment-Cooling Fans

Keep electronics cool in wet areas. These fans withstand weather, washdowns, and occasional time spent underwater. A ball bearing keeps them running smoothly and quietly, reducing friction to increase their lifespan.

Edge-Flow Equipment-Cooling Blowers

For use in tight spaces where other equipment-cooling blowers won't fit, air enters through the center of these blowers and then expels along the edges. They create a more concentrated stream of air than equipment-cooling fans to blow away the heat generated by electronic equipment, induction heaters, and high-wattage bulbs. Use them to keep heat-sensitive equipment such as electronic components cool.

Square blowers have UL recognized components and are CSA certified.

Bench-Top DC Fans

With Slotted Guard

With Honeycomb Guard

Mount these fans on a bench top or in a vehicle.

Ball-and-socket swivel base fans easily adjust with a thumb screw and do not oscillate, so they are ideal for applications where you need to move your fan frequently. However, they may loosen in applications with frequent vibration. Adjustable-tension swivel base fans tighten into place with an L-key and a wrench, so they are ideal for applications with frequent vibration. However, they are not as easy to reposition as fans with a ball-and-socket swivel base.

Slotted guards prevent debris and other objects from coming into contact with the fan blade. Honeycomb guards prevent fingers and small objects from coming into contact with the fan blade.

DC Heater and Air Conditioner Duct Booster Fans

Often used in vehicles, these fans operate on DC power. Insert them directly into your ductwork. They give small heaters and air conditioners a boost to circulate air through ductwork. All have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

DC Blowers

Operate these blowers with a DC power source, such as your vehicle battery. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting.

Blowers with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments.

Blowers with a multidirection mounting bracket can be rotated to discharge air in any direction.

Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Thermoelectric Coolers for Enclosures

Cooler Shown with Extension Bracket Installed

Cooler

Extension Bracket

Drain Kit

Also known as Peltier coolers, these coolers use electrical current to transfer heat away from your enclosure while sealing out contaminants. They cool the enclosure to below the ambient temperature. The solid-state thermoelectric components require no maintenance and take up less space than an air conditioner or heat exchanger.

Rated IP66 and NEMA 4X, these coolers withstand weather, washdowns, and corrosive environments. They meet American and European safety standards.

Coolers without a thermostat run continuously when powered. Add a thermostat, timer, or switch to turn them on and off.

An optional extension bracket holds the cooler away from the enclosure wall for more space inside the enclosure.

Add a drain kit to remove moisture when condensation is likely, such as in humid environments and enclosures exposed to rapid temperature changes. The included hose directs water away from electrical components.
