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.

What is a Tubeaxial Fan? 3234 Items
A Tubeaxial Fan (FAN,TUBEAXIAL) is a nonpositive displacement mechanical device without guide vanes and having an axial fan impeller inclosed within a tubular housing. It is designed primarily for duct installation to move air or gas axially over a wide range of volumes at medium pressures.
What is a Vaneaxial Fan? 2436 Items
A Vaneaxial Fan (FAN,VANEAXIAL) is a nonpositive displacement mechanical device with guide vanes and having an axial fan impeller(s) inclosed within a tubular housing. It is designed primarily for duct installation to move air or gas axially over a wide range of volumes and pressures.
What is a Centrifugal Fan? 3621 Items
A Centrifugal Fan (FAN,CENTRIFUGAL) is a nonpositive displacement mechanical device having a centrifugal fan impeller inclosed within a housing. It is designed to move air or gas over a wide range of volumes and pressures. The air or gas is drawn in axially and discharged radially or drawn in radially and discharged axially by centrifugal force through an outlet in the housing.
What is a Ventilating Fan? 952 Items
A Ventilating Fan (FAN,VENTILATING) is a nonpositive displacement mechanical device having either an axial or centrifugal fan impeller. It is designed to move free air or gas from indoors to outdoors or vice versa over a wide range of volumes at low pressures. It is supported by a ring, plate, or shroud or may be inclosed in a housing. It is designed for installation in a window, roof or wall opening, or the like.
What is an Axial Fan Impeller? 2360 Items
An Axial Fan Impeller (IMPELLER,FAN,AXIAL) is an item with blades or vanes equally spaced radially around the periphery of a hub, flange, or rotor. It is the rotating part of an axial type fan, electric motor, generator, and the like which creates a flow of air or gas parallel to the axis of rotation.
What is a Centrifugal Fan Impeller? 1385 Items
A Centrifugal Fan Impeller (IMPELLER,FAN,CENTRIFUGAL) is an item with blades, vanes, or paddles equally spaced radially or horizontally around the periphery of a hub, rotor, or wheel.
