LHC689AF Original Excavator Air Conditioner Filter for ZX200-5A

The part number LHC689AF is the original air conditioning filter (air conditioning filter element) provided by Hitachi for the ZX200-5A hydraulic excavator. As the intake air filtration core of the cabin air conditioning system, it is used to efficiently intercept particles such as dust, pollen, and dust in the air, ensuring clean air in the cabin and the health of operators. According to the universality rules of Hitachi accessories, this filter is usually also suitable for ZX200-5A same platform models (such as ZX200-5G, ZX210-5A, etc.), and the universal number may include similar models such as LHC689AE, LHC689AG, etc. It is strongly recommended to check the equipment nameplate to confirm the exact range of adaptation for the part number.

This product is a Hitachi pure air conditioning filter element, using ultrasonic and rubber fiber composite technology, with high filtration accuracy and long service life. The typical structure is a folding design to increase the filtering area and reduce wind resistance; The filter material is usually high-performance polyurethane material or fiberglass composite material, and the filtration efficiency for particles ≥ 0.3 μ m can reach 99.97%. The external dimensions should match perfectly with the filter slot of the ZX200-5A air conditioning bellows, with a wide and reliable sealing surface to prevent unfiltered air leakage. The working temperature range is about -30 ℃ to+70 ℃, with high humidity resistance, suitable for the dusty and vibrating working environment of construction machinery.

Replacement cycle: It is recommended to check/replace every 200-500 working hours, and in dusty and highly polluted environments (such as mines and demolition sites), it should be shortened to 100-200 hours. Daily inspection: visually inspect the surface of the filter element weekly for severe dust accumulation and any damage. Cleaning method: If there is only a lot of dust on the surface of the filter element, compressed air (pressure ≤ 0.3MPa) can be used to blow it in reverse from the inside to the outside; If it has turned black, moldy or structurally damaged, it must be replaced with a new part. Replacement steps: 1 Turn off the air conditioning power and disconnect the negative terminal of the battery; 2. Open the passenger compartment storage box or the rear filter access cover of the driver's cabin; 3. Remove the old filter element in the direction of the arrow, paying attention to the installation direction; 4. Clean the filter slot, install a new filter, and ensure that the sealing strip is tightly pressed; 5. Restore the power and test whether the air conditioner is running normally.
