Overview
The Dayton 3LE75 is a standard square AC axial cooling fan designed for compact equipment and cabinet ventilation in industrial automation applications. Operating at 115V AC with 50/60Hz dual-frequency support, this fan delivers 31 CFM of airflow in a space-constrained footprint. The cast-aluminum housing and shaded-pole motor design make it a reliable choice for spot cooling of electrical enclosures, control panels, and instrumentation cabinets.
Key Features
- 31 CFM airflow — adequate spot cooling for standard electrical cabinets
- Dual-frequency 50/60Hz — operates globally; 50 Hz reduces CFM by approximately 20%
- Compact square form factor — 3 1/8 in width, 1.5 in depth; fits tight enclosure spaces
- Low power consumption — 0.13A at 115V for energy-efficient operation
- Shaded-pole motor — single-speed, non-speed-controllable design for reliable long-term service
- RoHS Compliant and CE Certified — meets international electrical safety and environmental standards
