Q: What is the function of the 11NA-72011 filter?

The core function of the 11NA-72011 fuel filter is to purify fluids, mainly including:
Removing impurities: By physical interception or chemical adsorption, particles, pollutants or harmful substances in fluids (such as water, oil, air) can be removed. For example, water treatment filters can reduce hardness or suspended solids.
Suppressing harmonics: In the electrical field, filters can attenuate high-order harmonics in the power supply (such as 10kHz~30MHz frequency band), reduce interference, and ensure stable operation of equipment.
Protection system: By filtering impurities or noise, it extends the lifespan of downstream equipment and improves overall efficiency. ‌

Q: How do you know if your fuel water separator is bad?

Malfunctions of automotive fuel water separators are usually manifested as abnormal engine performance, such as unstable or weak acceleration, emission of black or white smoke, due to the entry of moisture and impurities into the fuel system, wear of fuel injectors, or insufficient combustion; At the same time, it may be accompanied by an increase in carbon deposits and fuel consumption, and long-term neglect may damage the engine. The malfunction indicator light on the vehicle dashboard is also an important signal (if it flashes, it indicates excessive moisture, and if it stays on, it may be a sensor malfunction).
The general diagnostic method includes observing the separation effect and checking the operating parameters:  the exhaust color and engine vibration can be observed

Q: How do you clean a micron filter?

Cleaning micro filters (such as microporous filters) requires corresponding methods based on specific types (such as household pre filters, water pipe filters, or industrial microporous filters). The following provide general steps and key precautions.

Preparation before cleaning:

First, turn off the water or power source, remove the filter, and record the installation sequence to prevent reset errors; Wear protective equipment such as rubber gloves, and prepare tools such as a soft bristled brush, neutral detergent, and clean water.

Cleaning steps:

• Rinse the surface: Rinse the surface of the filter element with clean water to remove large particles and impurities.
• Soaking and Brushing: Choose a mild detergent (avoiding corrosive cleaning agents) according to the filter material, gently scrub with a soft bristled brush, and do not use hard tools to avoid damaging the microporous structure.
• Thoroughly rinse: Rinse repeatedly with running water until there is no detergent residue.
• Drying and resetting: After natural air drying or blowing with compressed air, reinstall and check if the sealing ring is intact.

Attention: If the filtration efficiency of the filter element is still low after multiple cleaning, it may need to be replaced; If the industrial microporous filter is severely clogged, backwashing or alkali soaking can be attempted, but the operating pressure limit must be strictly followed (such as not exceeding 0.3MPa).
