Overview
The Dayton 4WT40 is a standard square axial fan engineered for reliable cooling in industrial control panels and electronic enclosures. Operating at 115V AC with 60/50Hz dual frequency capability, this fan delivers 30 CFM of airflow at zero static pressure. The compact square form factor (3-1/8″ × 3-1/8″) makes it ideal for space-constrained installations while maintaining robust thermal performance for continuous operation.
Key Features
