This 4-inch premium inline fan features overall dimensions of 11 inches x 11 inches x 7.5 inches. A tough, powder-coated finish allows it to withstand high-humidity environments, giving it versatility. It can be used in hydroponic systems, indoor growing rooms, clean-rooms, commercial filtration, cooling, air-scrubbing and ventilation, or anywhere a premium-grade inline fan is needed. Its professional grade motor uses a precision wound .70-amp, 80-watt motor with a sealed bearing system designed for continuous use. An aerodynamic body and ducted fan design combine for maximum efficiency, overcoming long ventilation runs and/or dense filtration. The body halves are sealed to eliminate air loss. The static pressure for this inline fan is 5.38 millibars. Its squirrel-cage turbine features 7 curved impeller blades each measuring 2 inches x 2 inches. Each blade is weighted and balanced within the cage and spin with the convex side facing forward for vibration-free, whisper quiet operation at just 55 decibels. The sturdy metal housing and turbine impeller are designed so they do not break or become brittle. It includes a removable leg/standoff for easy mounting. Its 1-inch deep collars allow for the easy connection of the ducts. Includes 4-inch premium inline fan, attached 10-foot grounded power cord with USA-standard 3-prong plug, and mounting brackets.
