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.

Low-Voltage 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. All have UL recognized components.

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

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.

Low-Voltage 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. All blowers have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments. An included multidirection mounting bracket lets you rotate the blower 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.

Enclosure Spot-Cooling Fans

DIN-Rail Mount

Surface Mount

Aim a stream of air at hot spots and equipment inside your enclosure to prevent overheating. Unlike other enclosure fans, they circulate air within your enclosure, so you don’t need to cut out an air intake. For precise adjustment, tilt the housing and spin the fan head to direct air where you need it. Use a thermostat, timer, or switch to turn fans on and off.

DIN-rail-mount fans snap onto DIN rail in four orientations with a dual DIN clip. Surface-mount fans can be screwed into the enclosure in any orientation.

Fans meet American, Canadian, and European safety standards. They also meet UL 94V0, so if they catch fire, they self-extinguish within 10 seconds and won’t spread the fire by dripping. Rated IP20, they’re designed so fingers can’t fit inside and get shocked.

Workstation Static Eliminators with Fan

With Quiet Mode

Replacement Filter

Replacement Filter Kit

Optional Articulating Arm

Spread the range of static control further than static eliminators without a fan. Small enough to fit on your desktop, these create an ionized field across your immediate workspace to protect against electrostatic discharge.

Static eliminators with a quiet mode have a slower fan speed than other static eliminators and are often used in small-parts and soldering applications. They’re also suitable for use in clean rooms rated to both Federal Standard and ISO classes.

Use the optional articulating arms for positioning the static eliminators.

The replacement filter kits contain one filter retainer, which holds a filter in place, and one filter.
