Specifications
The document outlines specifications for various models of industrial oscillating fans, including TW20B/W, TW24B/W, TW24HVB/W, TW30B/W, and TW36B/W. These models vary in size from 20" to 36" and have horsepower ranging from 1/4 to 1/2 HP. All models operate at 115 volts, 60 Hz, single phase, and offer high/low speed settings. They are available in black or white and come with a 10-foot cord.

Performance
The fans' performance is measured in terms of airflow (cfm), air velocity (fpm), efficiency (cfm/W), and sound level (dBA). For example, the TW20B/W model has an airflow of 4100/3400 cfm and a sound level of 63/60 dBA. The cooling area is determined by a minimum air velocity of 175 fpm, with coverage ranging from 1600 sq. ft for the 20" model to 4000 sq. ft for the 36" model.

Design and Technology
Schaefer's oscillating fans are designed for industrial use, providing extensive coverage in manufacturing, distribution, and service centers. The fans can be adjusted for targeted airflow, and the oscillation feature can be turned off if needed. The fans utilize high-quality metal gear design for the oscillating motors, offering greater load capacity, robustness, accuracy, and resilience compared to plastic gears.

Advantages of Metal Gears
Metal gears provide several benefits, including greater dimensional stability, the ability to operate at extreme temperatures, and resistance to chemicals and lubricants. They are less likely to stress and distort with aging, ensuring reliability and longevity.

Warranty and Assembly
The fans come with a 2-year warranty and are proudly assembled in the USA.
