Our filter fan series includes NEMA ratings for virtually every application. The Advantage Series Filter Fans, with a NEMA 12 rating, are available in a variety of sizes and cooling capacities. The Advantage Sentry Series electrical control panel fans, rated for NEMA 3R, offer the versatility and convenience of indoor or outdoor cooling, and are available in a variety of sizes, voltages and protection levels for electrical control panels. Our exclusive Guardian/GuardianX Series Filter Fans are rated for NEMA 4 or 4X, and are perfect for wash-down environments, wastewater and other challenging applications where the electrical control panels only require enclosure fans to provide the cooling. A variety of accessories and options for enclosure fans are available, including airflow detectors (to alert users to low air volume), reverse airflow options, and replacement filters. Keeping the enclosure fan filter clean will optimize airflow, resulting in better electrical cabinet cooling. Kooltronic also designs and manufactures a variety of enclosure fans to meet unique specifications. If this is something you may be interested in, please inquire about our modification and custom-design capabilities. For proper enclosure cooling fan selection, it is important to consider the heat that needs to be removed from the electrical cabinet and the required airflow against static pressure to achieve the desired result. Space limitations, the enclosure's NEMA requirements, and available power voltage should also be considered. However, if conditions require below ambient cooling of an enclosure, an air conditioner or a water-to-air heat exchanger should be considered, along with additional enclosure accessories that can help customize the unit.
