LHC685AF Original Excavator Air Conditioning Filter for ZX240-3

The part number LHC685AF is an original air conditioning filter provided by Hitachi for medium-sized hydraulic excavators such as ZX240-3. This component is used for air filtration in the cabin air conditioning system, protecting the blower, evaporator, and ensuring clean air in the cabin. Its universal models usually cover 20-24 ton same platform models such as ZX240-3, ZX240-5G, ZX210-3, as well as other Hitachi equipment with similar air conditioning box structures. As a core maintenance component of the original factory, its size is precisely matched with the air conditioning filter slot. It is strictly prohibited to use auxiliary components with dimensions that do not match, in order to avoid filter failure, insufficient air volume, or dust entering the cab.

This product is a Hitachi pure dry air conditioning filter element, with a black engineering plastic frame and a white high-performance electrostatic melt blown non-woven filter material inside. Its fibers are fine and evenly arranged. High filtration accuracy, capable of effectively intercepting particles such as dust, pollen, and willow catkins with a size of ≥ 0.3 microns, with an initial filtration efficiency typically ≥ 99.5%. The frame edge is equipped with foam rubber sealing strips to ensure no unfiltered air leakage after installation. The working temperature range is about -20 ℃ to+60 ℃, and it can withstand the humidity and wind pressure of the air conditioning system. Its low wind resistance and high dust holding capacity design can provide long-term protection while ensuring sufficient air intake. The "1" on the packaging label indicates a single package.

Replacement cycle: It is recommended to replace it every 250-500 working hours or every 3-6 months. In dusty environments such as mines and demolition, it should be shortened to 100-250 hours. Replacement steps: 1 Turn off the air conditioning and engine; 2. Open the inspection cover of the passenger side or rear filter element in the cab; 3. Remove the old filter element in the direction indicated by the arrow; 4. Clean the dust in the filter slot with a damp cloth; 5. Install the new filter element in the direction of the arrow, ensuring that the sealing strip is tightly pressed and there are no gaps; 6. Reinstall the maintenance cover.
