A Fluid Filter Cover (COVER,FLUID FILTER) is a rigid item of various shapes designed as a component of a fluid filter, acting as the cover and retaining the filter element in place. The item does not have an inlet or outlet connection. It is fastened onto the FILTER BODY, FLUID by means of clamps or bolts. For items with inlet and/or outlet connections, see HEAD, FLUID FILTER.

What is a Fluid Filter Head?

A Fluid Filter Head (HEAD,FLUID FILTER) is a component of a fluid filter designed to contain the inlet and/or outlet ports of the filter. It acts as a cover and attaches to the fluid filter body or mounts directly to an integral cavity in an engine, manifold, casing, or the like. The item may include relief, check, by-pass valves, and/or fluid filter element(s). It may have means for supporting the filter element(s), and means for mounting the filter. Excludes HEAD, SEDIMENT STRAINER and COVER, FLUID FILTER.

What is a Fluid Filter Body?

A Fluid Filter Body (FILTER BODY,FLUID) is a component of a FILTER, FLUID designed to contain the FILTER ELEMENT, FLUID and attach to the HEAD, FLUID FILTER or the COVER, ACCESS. It may have inlet and/or outlet connections, means for mounting a drain plug(s), check, relief and or by-pass valves. Excludes BOWL, SEDIMENT.See also STRAINER BODY, SEDIMENT.

What is a Fluid Filter?

A Fluid Filter (FILTER,FLUID) is a filter having inlet and outlet connections and designed to be connected in a pipe, tube or hose line. For spin-on, base-mounted filtering devices with integral outer casings, see FILTER ELEMENT, FLUID. Excludes AIR CONDITIONER.

What is a Fluid Filter Assembly?

A Fluid Filter Assembly (FILTER ASSEMBLY,FLUID) is two or more FILTER, FLUID on a common mounting or mounted on each other. They may be separable and operate in series, parallel, or individually.

What is a Fluid Filter Element?

A Fluid Filter Element (FILTER ELEMENT,FLUID) is a replaceable device designed to remove solid particles from fluids ranging in density from heavy liquids to gases. The removal of particles is accomplished by porous material (metallic or non-metallic), stacked disks, wound wire, or the like, constructed so the fluid can flow through the device while the solid particles are retained. It may be designed to fit into a FILTER, FLUID (or similar cavity), or it may have an integral outer casing and mounting facilities and be designed to connect directly to an engine, compressor, or the like. The degree of removal of particles must be nominally rated at less than 50 microns or absolutely rated at less than 75 microns. Excludes FILTER ELEMENT, AIR CONDITIONING. See also STRAINER ELEMENT, SEDIMENT.

What is an Air Filter Parts Kit?

An Air Filter Parts Kit (PARTS KIT,AIR FILTER) is a collection of items used to repair/replace air filters. May include mounting hardware. Excludes PARTS KIT (1),BRAKE CHAMBER.

What is an Intake Air Cleaner Filter Body?

An Intake Air Cleaner Filter Body (FILTER BODY,INTAKE AIR CLEANER) is a part of an AIR CLEANER, INTAKE designed as a housing for a FILTER ELEMENT, INTAKE AIR CLEANER. Depending on the configuration, the item may be mounted at the top, the bottom or by means of a flanking flange. In general, the housing is a multipiece item and has air intake and air outlet.

What is a Vehicular Engine Filter Warning Indicator?

A Vehicular Engine Filter Warning Indicator (INDICATOR,FILTER WARNING,VEHICULAR ENGINE) is a mechanical indicator used on vehicular engines for dry or liquid type clearners to provide a visual warning signal when filter needs cleaning or changing.

What is an Intake Air Cleaner Filter Element?

An Intake Air Cleaner Filter Element (FILTER ELEMENT,INTAKE AIR CLEANER) is a replaceable device designed to remove dust, pollen or other foreign matter from the air passing through it. The removal of particles is accomplished by porous material (metallic or non-metallic), wire mesh, or the like. It is designed to fit into an AIR CLEANER,INTAKE.

NATO Supply Class 2940 is a classification within NATO Supply Group 29, which is dedicated to Engine Accessories. Specifically, NATO Supply Class 2940 focuses on Engine Air and Oil Filters, Strainers, and Cleaners for non-aircraft applications.

This class includes various types of filters, strainers, and cleaners that are used in engines to ensure the quality and cleanliness of the air and oil that flows through them. These components play a crucial role in maintaining the performance and longevity of engines by preventing contaminants from entering and causing damage.

Engine air filters are designed to remove dust, dirt, and other particles from the air intake, ensuring that only clean air enters the engine for combustion. Oil filters, on the other hand, are responsible for removing impurities and contaminants from the engine oil, preventing them from circulating and causing wear and tear on engine components.

Strainers are used to filter out larger particles or debris from fluids, such as fuel or coolant, before they enter the engine. This helps to prevent blockages and damage to the engine's internal components.

Cleaners in this class refer to products used to clean and maintain the filters and strainers, ensuring their optimal performance and longevity. These cleaners may include specialized solvents or cleaning agents designed to remove accumulated dirt, oil, or other contaminants from the filters and strainers.

It's important to note that this classification specifically pertains to non-aircraft applications. For aircraft engine filters and accessories, there are separate classifications within the NATO Supply System.

Overall, NATO Supply Class 2940 encompasses a range of essential components for maintaining the cleanliness and efficiency of engines in non-aircraft applications.
