Q: How often should Donaldson filters be changed?

The replacement cycle of Donaldson filters varies greatly depending on the type of filter, specific application conditions, and usage environment, and there is no unified time standard. The core principle is to maintain according to actual needs, rather than relying solely on fixed time or mileage. ‌
The following is general reference information for different types of Donaldson filters:

1. Air filter (taking engine intake as an example)

Main criteria for judgment: resistance (pressure difference). Priority should be the pressure differential indicator attached to the filter element. When the resistance level reaches the maximum recommended value by the engine or equipment manufacturer, replacement is necessary. ‌
Theoretical mileage reference: For long-lasting air filters used in vehicles, some models (such as the Blue series using Ultra Web technology) have an average service life of over 60000 kilometers. But it is usually recommended to replace the air filter of a regular sedan at around 15000 kilometers, while it is about 20000 kilometers for commercial vehicles. ‌

Important influencing factors: In harsh environments with high levels of dust, the replacement cycle needs to be significantly shorten, possibly not exceeding 10000 kilometers.
Maintenance suggestion: Regularly check the dust collection cup and empty it according to the accumulation of dust. The safety filter element is usually replaced every three times after replacing the main filter element. ‌

2. Hydraulic system filter element

The replacement cycle of hydraulic filter element is relatively short because the hydraulic system requires extremely high oil cleanliness. ‌
Hydraulic filter element: You can replace it every 3 to 6 months.
Hydraulic oil filter element: The replacement cycle is slightly longer, usually 6 to 12 months.
Hydraulic return oil filter element: High filtration accuracy, relatively durable, generally can be for 2 to 3 years. ‌

3. Compressed air filter cartridge

For compressed air system filters used in factories and other places, the replacement cycle should also combined with monitoring and timing. ‌
Pre filter and final filter cartridge: You can check the condition of the filter cartridge every 3 months. The integrity can be monitored through the dryer display screen or a dedicated application, and whether to replace it can be determined according to actual needs. ‌
Adsorbent cartridge: It usually needs to be inspected and maintained annually or every time before replacing. ‌

Q: Do Donaldson filters come with a warranty?

Yes, Donaldson filters offer warranty service, but the specific warranty policy varies depending on the product type. ‌For example, for air filtration products, the warranty period is usually 1 year, calculated from the date the product is into use or first served. ‌

Other products such as liquid filters or exhaust components may have different warranty periods, for example, exhaust mufflers can provide up to 8 years of warranty. ‌But the warranty does not cover malfunctions caused by misuse, improper installation, negligence, or non Donaldson approved modifications. ‌If a malfunction occurs, You must write notice to Donaldson Company within one year, and they will decide on the repair or replacement method. ‌

If you have specific product models or application scenarios, we recommend contacting Donaldson's sales support team directly for more accurate warranty information. ‌

Q: How to Use Water Absorbing Filters?

This refers to "water absorbing filters" in industrial or professional fields
This type of equipment is usually used for precision filtration of liquids such as fuel and hydraulic oil. Its core function is to adsorb and filter out moisture in the liquid, rather than directly "absorbing water".

Core working principle and usage points:

Core function: It uses high-performance composite filter materials (such as absorbent media) internally to stably adsorb water in the liquid, ensuring that the filtered oil has an extremely low water content. ‌
Application scenarios: Commonly used in the fuel supply system of diesel engines, refueling equipment at gas stations, and fuel processing systems in laboratories. ‌

Precautions for use:

Installation and connection: Professional personnel must install it in the pipeline according to specifications and ensure that the connection is well sealed. ‌
Parameter setting: Adjust the filtration accuracy and working parameters of the system based on the impurities in the filtered liquid. ‌
Monitoring and maintenance: During operation, it is necessary to monitor the pressure difference. When the pressure difference exceeds the set value, it indicates that the filter element may be clogged and needs to be backwashed or replaced. It is crucial to regularly check the saturation water absorption and cleanliness of the filter element. ‌

Q: What are water absorbing filter elements?

A water absorbing filter element is a specialized filtration device used to remove moisture and impurities from liquids (usually oil products such as diesel and gasoline). It achieves filtration function through composite filter materials and uses high-performance absorbent media to ensure effective separation of moisture and interception of solid particles during the filtration process. ‌

This type of filter is commonly used in fuel dispensers and other scenarios, adopting a multi-layer structure design: the first layer filters impurities roughly, the second layer filters moisture specifically, and the third layer filters fine to prevent equipment failure or safety accidents caused by oil containing water or impurities. For example, at a gas station, it can handle situations such as unloading and dispensing at the same time, and oil tank seepage after rain to avoid adding water and impurities. ‌

The core function of a water absorbing filter element is to protect downstream equipment (such as engines or oil storage systems), extend their lifespan, and ensure the quality of oil products. ‌
