Dayton 5JLP4 Propeller 6 5/8 in 25 Degree Pitch

Dayton 5JLP4 Propeller Overview

The Dayton 5JLP4 is a high-temperature propeller designed for ceiling-fan applications where elevated ambient conditions occur. Its white plastic construction and press-fit bore suit maintenance teams and OEM integrators replacing worn impellers on compatible motor shafts. The five-blade layout with a 25-degree pitch targets airflow requirements in commercial or industrial settings. Buyers needing a different blade count, bore size or rotation direction should look elsewhere.

Sustained Airflow Performance

Rated at 180 cfm at 3000 RPM, the propeller delivers consistent air movement when driven by a 1/40 hp motor under continuous duty. The 25-degree blade pitch maintains steady pressure rise across the operating envelope without the drop-off seen in short-burst testing. Plastic blades resist deformation at the maximum ambient temperature of 200 degrees F, preserving aerodynamic profile during extended runs. Installations demanding higher static pressure or variable-speed curves will require a different blade geometry.

Thermal and Power Characteristics

The propeller itself adds negligible heat; thermal load is determined by the driving motor and the 200-degree-F ambient ceiling. With a recommended motor of only 1/40 hp, power draw remains minimal, keeping circuit loading low in multi-fan arrays. CW facing discharge rotation directs airflow predictably, simplifying duct layout. Environments exceeding the stated temperature limit or requiring reversible airflow are not served by this model.
