Aviation oil purifiers are high-precision filtration equipment specially used in the aviation field. They are mainly used to purify aviation fuel, hydraulic oil, lubricating oil, etc. to ensure the safe operation of aircraft systems. The following are the main types of aviation oil purifiers and their characteristics:


1. Aviation fuel oil purifiers

1.1 Purpose

- Used to filter aviation fuel (such as Jet A, Jet A-1, JP-8, etc.) to remove moisture, solid particles and other pollutants.


1.2 Features

- High-precision filtration: The filtration accuracy is usually 1-5 microns to ensure that the fuel cleanliness meets aviation standards.

- Dehydration function: Equipped with a vacuum dehydration system to remove moisture from the fuel.

- Explosion-proof design: Meet the explosion-proof requirements of the aviation field to ensure safe operation.

- Portability: Some equipment is designed to be portable, which is convenient for use at airports or hangars.


2. Aviation hydraulic oil purifiers

2.1 Purpose

- Used to filter the hydraulic oil of the aviation hydraulic system to remove particulate pollutants and moisture to ensure the efficient operation of the hydraulic system.

2.2 Features

- High cleanliness: The filtration accuracy can reach 1 micron, meeting the strict requirements of aviation hydraulic systems.

- Efficient dehydration: Vacuum or coalescence separation technology is used to remove water from hydraulic oil.

- High-pressure resistance: The equipment can withstand the high-pressure environment of the hydraulic system.

- Automatic control: Equipped with an automatic control system to monitor the oil status in real-time.


3. Aviation lubricant oil purifier

3.1 Purpose

- Used to filter aviation engine lubricating oil, remove wear particles, carbon deposits and other contaminants, and extend engine life.


3.2 Features

- High-temperature tolerance: Able to handle high-temperature lubricating oil to ensure filtration effect.

- High-precision filtration: The filtration accuracy is usually 3-10 microns, which meets the engine lubrication requirements.

- Degassing function: Remove bubbles in the lubricating oil to prevent cavitation.

- Long-life filter element: Use high-quality filter elements to reduce the frequency of replacement.


4. Multifunctional aviation oil purifier

4.1 Application

- Suitable for filtering a variety of aviation oils, including fuel, hydraulic oil and lubricating oil.

4.2 Features

- Multifunctional integration: One device can handle a variety of oils and improve the efficiency of use.

- Modular design: Different modules can be configured according to needs, such as dehydration, degassing, heating, etc.

- Intelligent control: Equipped with an intelligent control system to achieve automated operation and remote monitoring.


5. Portable aviation oil purifier

5.1 Application

- Used for oil filtration and maintenance at airports, hangars and other sites.

5.2 Features

- Lightweight and portable: The device is small in size and light in weight, making it easy to move and operate.

- Quick connection: Equipped with quick connectors for easy connection to aircraft systems.

- High-efficiency filtration: Despite its small size, it still has high-precision filtration capabilities.


6. Key technologies of aviation oil purifiers

- High-precision filtration: Use multi-layer filter elements or special filter materials to ensure the cleanliness of the oil. - Vacuum dehydration: remove water from oil through vacuum technology.

- Coalescing separation: used to separate tiny water droplets in oil.

- Heating system: improve oil fluidity and enhance filtering effect.

- Explosion-proof design: meets safety standards in the aviation field.
