Dayton 2RTH1 Axial Fan 2 3/8 in² 31.5 CFM 24V DC HVAC Circulator

Description

Product Overview

The Dayton 2RTH1 axial fan is engineered to deliver consistent, high‑efficiency airflow in demanding industrial and scientific environments. With a rated capacity of 31.5 cubic feet per minute (CFM) and a low‑voltage 24 V DC power requirement, this fan balances performance and energy consumption, making it an ideal choice for HVAC circulators, equipment cooling, and ventilation systems where space is at a premium. Its compact 2 × 3/8 in² (approximately 2 × 0.375 in) footprint measures just 2 × 2 × 2 inches and weighs only one pound, allowing for easy integration into confined enclosures, control panels, and custom‑built machinery. Constructed from robust, corrosion‑resistant materials, the fan’s impeller and housing are designed to withstand continuous operation, dust exposure, and temperature fluctuations typical of industrial settings. The product’s specifications, including a package dimension of 2 × 2 × 2 inches and a first‑available date of September 5 2014, reflect a mature design that has earned a solid reputation among engineers and maintenance professionals.

Usage

Designed for versatility, the Dayton 2RTH1 axial fan excels in a variety of real‑world applications. In HVAC systems, it provides supplemental airflow to improve heat exchange efficiency, reduce fan noise, and maintain optimal temperature differentials across coils and ducts. Its low‑voltage operation makes it suitable for battery‑backed or solar‑powered installations, where energy conservation is critical. In manufacturing facilities, the fan can be mounted on machinery to cool motors, drives, and electronic controllers, preventing overheating and extending equipment lifespan. The fan’s small size also enables use in portable ventilation units, laboratory fume hoods, and enclosure cooling for 3D printers or CNC machines. Because the fan operates at 24 V DC, it integrates seamlessly with existing DC power rails, eliminating the need for additional AC‑to‑DC conversion hardware. The fan’s quiet operation and low vibration profile make it appropriate for environments where acoustic performance matters, such as clean rooms, medical equipment, and office‑grade HVAC retrofits.
