Dri-Eaz vortex axial fan is a single-speed fan with a 1. 0 horsepower motor that draws 7. 4 amperes on a 115 volts power supply for energy efficiency. It has a maximum rated airflow of 2041 cubic feet per minute and can propel air across large open areas like gyms, hallways, concrete pads, and similar spaces for drying applications. This fan can propel air through up to 125-feets of ducting (sold separately) for ventilation or to create negative pressure in confined areas such as crawlspaces. It is stackable with other Dri-Eaz vortex axial fan units for efficient use of storage space, and it is built to comply with Underwriters Laboratories and Canadian Standards Association safety standards. Air movers increase airflow to ventilate spaces and to help evaporate water from carpets, drywalls, baseboards, sub-floors, and many types of building materials or structures that need to be ventilated or dried. They typically consist of a motorized fan or blower wheel, and housing. Air movers are commonly used for drying applications in the cleaning, building maintenance, and restoration industries. Improve indoor air quality; remove unwanted odors. A built-in handle and simple 1-speed switch make operation a snap. Static pressure: 3. 2-inches. Blue color. Measures 19-13/64-inches height by 18-45/64-inches width by 15-45/64-inches depth.
