High efficiency inline duct fan for ventilation systems in residential and commercial applications where infinite airflow controllability is required. Economical use of energy and ease of control help this fan match the demand of any job. The fan comes with a built-in 0-10 V potentiometer that makes it easier to find the preferred working point without any additional wiring. Typical applications for FG. EC fans are supply or exhaust air duct systems in offices, day care facilities, schools, gymnasiums, crawl spaces, manufacturing facilities. Product can be configured with external devices that adjust airflow-based on actual demand such as day/time schedule, occupancy, CO2 level and more. The fan can also be used as a duct booster for extra long duct runs in single-family homes. The housing is manufactured from a two-piece stamped, galvanized construction. The two halves are joined using Fantech's unique folded seam closure, which gives the fan the first in class, airtight seal. The fan motors can operate in temperatures of air up to 140 deg F and the motor bearings are permanently sealed, self-lubricated for maintenance-free life. FG 4XL EC has built-in thermal overload protection with automatic reset needing no user intervention. With the motor in the airstream, the fan provides the constant dissipation of heat build-up thus giving the fan best in class for longevity and reliability. For the same air volume, FG 4XL EC consumes considerably less energy than an AC fan of its size. The mounting bracket and hardware are included, the fan is ENERGY STAR certified and comes with 5 years factory warranty.
