1. Basic Product Information
Brand: Xuman
Model: P763995
Primary Type: Heavy-Duty Air Filter
Secondary Application: Can also be used as a safety filter element (secondary filter) or as a crankcase ventilation filter for internal combustion engines in certain equipment.
Installation Method: Radial seal, installed in a specific air filter housing.

2. Key Features and Applications
Primary Function (as Main Air Filter): Used to filter dust, sand, and other impurities from the air entering the engine, serving as a critical component to protect the engine from wear.
Primary Function (as Safety Filter): In a two-stage air filtration system, it acts as an internal second line of defense. If the main filter is accidentally damaged or improperly sealed, the safety filter provides protection to prevent dust from entering the engine. When used as a safety filter, its filtration efficiency is typically extremely high.
Application Areas: This filter is widely used and is a standard configuration for many top-tier construction machinery and diesel engines, such as excavators, loaders, bulldozers, and generator sets.

3. Technical Parameters (Typical Characteristics)
Filtration Efficiency: Utilizes high-efficiency nanofiber or premium filter paper technology, offering high initial and full-life efficiency, effectively capturing sub-micron particles.
Dust Holding Capacity: Designed with deep pleats for high dust holding capacity and long service life, reducing replacement frequency.
Sealing Material: Typically uses high-quality polyurethane (PU) end caps and sealant to ensure perfect sealing even under harsh operating conditions, preventing air leakage.
Structure: Equipped with a metal inner mesh support tube for robust construction, preventing the filter pleats from collapsing.
