The "Deep purification Guardian" of hydraulic systems - Mitsubishi 35A40-01800 bypass filter
Although the bypass filter is not a core component of the hydraulic or lubrication system, it plays an "active purification" role and directly affects the cleanliness of the system oil and the lifespan of the components. The Mitsubishi 35A40-01800 bypass filter, with its original factory-level quality and precise design, has become the key to ensuring the long-term operation of the system. Its core value lies in the dual advantages of "precise matching" and "deep filtration".
As an original Mitsubishi accessory, the size, interface and system pipeline of 35A40-01800 are perfectly matched (for specific compatible models, please consult customer service). Its bypass structure and flow parameters are calibrated by the original factory and can be seamlessly integrated into the hydraulic or lubrication circuit. Unlike the possible installation misalignment or flow mismatch of general filters, it can achieve oil "diversion and purification" without interfering with the pressure of the main oil circuit. Some of the oil is precisely filtered by the filter and then returned to ensure that there is always clean oil circulating in the system, avoiding the "purification blind zone" caused by improper filter matching.
Filtration efficiency is its core competitiveness. It adopts multi-layer gradient filter materials: the outer layer intercepts large particles such as sand and metal debris, the middle layer adsorbs the gum produced by the oxidation of oil, and the inner layer filters fine impurities smaller than 5 microns. Even in a construction site environment with a lot of dust and high vibration, it can still maintain a filtration efficiency of over 98%. More crucial is the "bypass protection" design: when the filter material is clogged (due to excessive resistance), the bypass valve automatically opens to prevent dry grinding of the system caused by oil flow interruption - this is particularly important for high-pressure hydraulic systems, as it can prevent the cylinder and pump body from being damaged instantly due to lack of oil.
Durable design is designed to handle complex working conditions. The filter housing is made of high-strength engineering plastic combined with metal, which is impact-resistant and resistant to oil erosion. The sealing rubber ring is made of high and low temperature resistant rubber, which remains elastic in an environment ranging from -30℃ to 120℃, effectively preventing oil leakage. This durability extends its lifespan by more than 50% compared to aftermarket parts, indirectly reducing faults such as valve group jamming and cylinder wear caused by impurity contamination. For equipment that relies on hydraulic systems, the selection of a high-quality filter can reduce maintenance costs several times over.
Maintenance suggestions: It is recommended to check the filter condition every 200 to 300 hours (or according to the cycle in the equipment manual). If the filter material is obviously dirty or the bypass valve is frequently opened, it should be replaced in time. When replacing, give priority to using original factory parts to ensure they are compatible with the system pressure and flow rate, and avoid the risk of "insufficient purification".
