Welcome to this critical analysis of the Filtre à air externe FAW J6P system for the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. This is the first line of defense for the cab’s HVAC system and the driver’s health. This guide analyzes the 5 key components that create this vital filtration system.
Le Filtre à air externe FAW J6P, also known as the cabin air filter, is a non-negotiable component for a heavy-duty dump truck. Operating in the extreme dust of quarries, chantiers de construction, and unpaved roads, the CA3250P66K2L1T1E is constantly exposed to airborne silica, pollen, suie, et débris.
This filter’s job is twofold: d'abord, it protects the driver’s respiratory health by providing clean, breathable air. Deuxième, it protects the HVAC system itself. Without this Filtre à air externe FAW J6P, the evaporator core would become clogged with a “blanket” of dust, destroying its ability to cool the cab.
This deconstruction will analyze the full assembly, including the two-piece housing, the all-important filter element, the rubber gasket, and the mounting hardware. Pour un technicien, a clogged or missing Filtre à air externe FAW J6P is the number one cause of all “low airflow” ou “poor A/C” complaints.
This is the functional heart of the Filtre à air externe FAW J6P. It is the single, replaceable component that does all the work.
1. Composant: ‘Filter Element-External Air Filter’ (8101574-A01) – Quantité 1
Ce (Marque 4) is the filter element, ou “cartridge.” It is a high-efficiency, pleated-media filter designed for a high-dust environment.
The Media Logic: This is not paper. The filter media is a synthetic, non-woven, electrostatically-charged material. Le “non-woven” design creates a complex, three-dimensional web of fibers that traps particles of different sizes. Le “electrostatic charge” acts like a magnet, actively pulling and holding microscopic particles (like dust and pollen) that would otherwise pass right through.
The Pleating Logic: The media is heavily “pleated” (folded) to maximize its surface area within a small box. This is critical. A high surface area allows the Filtre à air externe FAW J6P to hold a massive amount of dust before it becomes restrictive, extending its service life.
The Activated Charcoal Logic: Many high-end filters, especially for the Filtre à air externe FAW J6P, are “combination filters.” They embed a layer of activated charcoal into the media. This charcoal’s function is to absorb odors, such as diesel fumes, exhaust gases (NOx, SOx), and other chemical smells from the job site, preventing them from entering the cab.
The System Protection Logic: Le #1 enemy of an A/C system is dust. This filter element is the only thing protecting the evaporator core. Without it, the evaporator’s fine aluminum fins become clogged with a thick, wet mat of dust. This blocks all airflow, causing the driver to complain of “no A/C” ou “no heat.” The evaporator ices over, and the backed-up condensation can flood the cab floor.
La logique de service: This is a primary, mandatory service item. For a dump truck, this filter may need to be replaced every 5,000 miles (or even more frequently) in severe dust. Un bouché Filtre à air externe FAW J6P is the most common, and cheapest, fix for a poor-performing HVAC system.
This is the two-piece, protecteur “shell” that holds the filter element (Cœur 1) and seals it against the truck’s body.
1. Composant: ‘Box A-External Air Filter’ (8101571-B27) – Quantité 1
Ce (Marque 1) is the main body or base of the Filtre à air externe FAW J6P housing. It is the part that bolts to the cab’s air intake plenum.
2. Composant: ‘Box B-External Air Filter’ (8101572-A01) – Quantité 1
Ce (Marque 2) is the removable “cover” ou “couvercle” of the housing. It is the part the technician removes to access and replace the filter element.
The Two-Piece Logic: Ce “clamshell” design is purely for service. The Box A (base) is semi-permanently mounted to the truck. The Box B (cover) is designed for quick removal, held on by clips or the two tapping screws (Cœur 4). This provides fast, “no-tools” access to the filter element.
La logique matérielle: Both housing pieces are injection-molded from a durable, high-temperature, and impact-resistant polymer (like glass-filled Polypropylene). This material is chosen because it is lightweight, résistant à la corrosion, and inexpensive to manufacture in complex shapes. It must be strong enough to resist cracking from vibration or minor impacts.
The Water Drainage Logic: This is a critical design feature. Le Filtre à air externe FAW J6P is located in the fresh-air plenum, which is exposed to rain and snow. The housing (Box A) is designed with a “water-shedding” shape and has built-in drain holes. This allows any ingested water to drain out *before* it can soak the filter element. A water-soaked filter blocks all airflow and will grow mold.
This group contains the components that ensure a perfect, airtight seal. An unsealed filter is a useless filter.
1. Composant: ‘Rubber Gasket-External Air Filter’ (8101573-A01) – Quantité 1
Ce (Marque 3) is a precision-molded rubber gasket. It is the most critical part of the Filtre à air externe FAW J6P housing.
The Sealing Logic: This gasket creates the airtight seal between the Box A (base) and the Box B (cover). It is designed to be compressed by the two tapping screws (Cœur 4). This seal is what *forces* all incoming air to go *through* the filter media (Cœur 1), rather than leaking around its edges.
Le “Unfiltered Air” Logique: A missing, cracked, ou “flat-spotted” gasket is a critical failure. It creates a path of least resistance. Air (et la poussière) will bypass the filter entirely, flowing through the gap in the seal. This sends 100% unfiltered, dirty air directly into the HVAC system, destroying the evaporator. Ce Filtre à air externe FAW J6P gasket is just as important as the filter itself.
2. Composant: « Vis taraudeuse à tête cylindrique à empreinte cruciforme’ (CQ2714816) – Quantité 2
Ce (Marque 5) is the set of two screws that provides the clamping force for the seal.
The Clamping Logic: These two screws (often supplemented by plastic clips) are what draw the cover (Box B) down onto the base (Box A). Their job is to apply the even pressure needed to fully compress the rubber gasket (8101573-A01) and create the perfect seal for the Filtre à air externe FAW J6P.
La logique de service: A technician must inspect the gasket (Marque 3) every time they replace the filter element (Marque 4). If the gasket is hard, cracked, or missing, it must be replaced. A technician must also be careful not to over-tighten the tapping screws (Marque 5), as this will strip the plastic housing and prevent a good seal.
