Type 3, 3R, 4, 4X Boxes and Enclosures WEATHERFLO Type 3R Vented Enclosures Critical Parameters (upper temperature limits) Enclosure Heat Load Calculations Drive heat: WD = [(HP x 745.7 Watts/HP) / E M] x (1-E D) [Watts] Total heat: Estimate an additional 25% a for wire connections and other components. W T = WD x 1.25 a [Watts] Required airflow: CFM = (W T x 3.16) / (Tint - Tamb) [ft. 3 / min.] This is an estimated factor.
