NATO Supply Class 4140 is a classification within NATO Supply Group 41, which is dedicated to Refrigeration, Air Conditioning, and Air Circulating Equipment.

Specifically, Class 4140 focuses on Fans, Air Circulators, and Blower Equipment. This class includes various types of equipment used for air circulation and ventilation purposes.

Fans are devices that create airflow by rotating blades or impellers. They are commonly used in HVAC systems, industrial settings, and residential applications to circulate air and maintain proper ventilation.

Air circulators, also known as air movers or air amplifiers, are designed to move large volumes of air in a specific direction. They are often used in industrial environments to improve air circulation, cool machinery, or remove fumes and odors.

Blower equipment refers to devices that generate a high-velocity airflow by using centrifugal force or positive displacement. They are commonly used in HVAC systems, industrial processes, and pneumatic conveying systems to move air or other gases.

NATO Supply Class 4140 covers a wide range of equipment, including various types and sizes of fans, air circulators, and blowers. These devices can be powered by electricity, gas, or other energy sources, depending on their intended application.

It is important to note that the NATO Supply Classification (NSC) system is used by NATO member countries to standardize the identification and classification of military and non-military items. The NSC helps facilitate procurement, logistics, and inventory management within NATO and its member nations.
