Aerotec was a design and manufacturing company founded in Brazil in 1962 under the auspices of the Brazilian General Command for Aerospace Technology (CTA) in Sao Jose dos Campos. Beginning in the late 1960s, the firm manufactured a two-seat trainer for the Brazilian Air Force, the Aerotec Uirapuru. A small number were also built for the civil market, and still others were exported to other Latin American countries. In 1987, the firm was sold to Embraer. The Aero Tec is also an air circulation fan produced by DL Manufacturing.
