Delta BreezGreenBuilder Ventilation Fan / Light Combo
Model: VFB050C4L1 (50 CFM)
Description
Low noise ceiling mount ventilating fan with DC Motor and light rated for continuous running. Evaluated by Underwriter Laboratories and conforms to both UL and cUL safety standards.
Dimensions
The fan unit has a main housing approximately 8.25 inches wide and 8.0 inches deep. The grille assembly is approximately 11.0 inches by 11.0 inches. It features a detachable 4.0-inch diameter duct adapter and a housing depth of approximately 5.75 inches.
Fan Curve
The fan performance curve graph plots Air Flow (CFM) on the horizontal axis against Static Pressure (in inches w.g.) on the vertical axis. The curve indicates that at 0.1 inches w.g. static pressure, the fan delivers 50 CFM, and at 0.25 inches w.g. static pressure, it delivers 38 CFM. The graph also shows performance points corresponding to increasing duct lengths (10ft to 50ft), indicating higher static pressure.
