Q: How often should I change a hydraulic filter?
There is no unified fixed time for hydraulic filter, which depends on the type of filter cartridge, equipment operating conditions, and manufacturer's manual. The conventional reference range ranges from several hundred to several thousand working hours.
🔍 When should I switch
The most common judgment is based on the number of working hours. The return oil filter should be replaced every 500 hours after the first 250 hours, while the suction filter can last up to 2000 hours. Generally, it takes 3-6 months or 1000-2000 hours to inspect and replace, and for harsh working conditions, it should be done in advance.
📋 What are the differences between different filter cartridges
The return oil filter has high filtration accuracy but is replaced frequently, while the suction filter is relatively durable. The overall filter system can be considered for major replacement after about 3 years. It depends on the material of the filter element and the nominal filtration accuracy.
🎯 How to make a more reliable judgment
Prioritize checking the equipment manual for accuracy, or use a pressure difference alarm to determine (if the pressure difference exceeds 0.3MPa, it needs to be replaced), or observe whether the oil is turbid or has impurities. Steel mills and other environments with high dust and high temperature and humidity need to shorten the replacement cycle.
Q: Can you clean and reuse a hydraulic filter?
Whether a hydraulic filter can be cleaned and reused depends on the filter element material and the manufacturer's design: metal mesh/sintered metal filter elements can be cleaned and reused, while paper/glass fiber filter elements must not be cleaned and must be replaced as a one-time use.
Core Evaluation Criteria
- Washable and Reusable: Surface filtration or high-strength structural filters such as stainless steel woven mesh and metal sintered felt are resistant to chemical corrosion and structurally stable. They can restore performance after specialized cleaning processes (typically labeled as "washable type").
- Non-washable (disposable): Filtration media such as cellulose filter paper and glass fiber, which are prone to fiber breakage, pore deformation, or structural collapse upon cleaning, resulting in complete loss of filtration precision. Forced cleaning may damage the hydraulic system
