OEM HITACHI ZAXIS ZX120 130 SERIES OUTER AIR FILTER (OEM L4486002) | Tonkee®

This outer air filter is constructed using high-quality materials designed to withstand the harsh operating conditions commonly encountered in construction and excavation equipment.

It typically consists of a sturdy plastic or metal frame, which provides structural support, and a filter media that is often made of pleated paper or synthetic fibers. These materials are chosen for their ability to effectively trap dust, dirt, debris, and other particulate matter that could enter the engine's air intake system.

Functionality:
The primary function of the outer air filter is to act as a barrier between the external environment and the engine's intake system. As air is drawn into the engine for combustion, the filter captures and retains harmful particles. This prevents contaminants from entering the engine, where they could potentially cause damage by abrasive wear, fouling of combustion components, or decreased overall efficiency.

Filtration Efficiency:
The performance of this outer air filter, like any other filter, is measured in terms of filtration efficiency.

It is designed to efficiently remove particles of various sizes, including fine dust and larger debris, ensuring that only clean air is allowed into the engine. The filter media's pleated design provides a larger surface area for trapping particles, thus enhancing filtration efficiency.

Compatibility:
The Hitachi ZAXIS ZX120/130 Series Outer Air Filter with OEM part number L4486002 is specifically engineered to fit these particular models. It is essential to ensure that replacement filters are compatible with the specific machinery to maintain optimal performance and prevent any issues related to incorrect fitment.

Maintenance and Replacement:
Regular maintenance and replacement of the outer air filter are crucial to keep the engine functioning optimally. The frequency of replacement depends on operating conditions, including the amount of dust and debris encountered during typical operations. In dusty environments, more frequent changes may be necessary to prevent clogging and maintain efficient filtration.
