Perfect for gyms, workshops, studios, and other quiet but warm environments, the SD4X features a totally-enclosed 1.5 HP TEFC motor that is built to run for years in tough conditions. Easy to install and maintain, this ceiling fan offers powerful ventilation to keep your space comfortable and productive.
Built with efficiency and versatility in mind, the SD4X operates quietly even while moving large volumes of air—making those dangerously hot summer days much more manageable.
