Product Introduction

Main Application Scenarios

This replacement element is specially developed for hydrocarbon liquid water removal and impurity filtration, covering aviation, petrochemical, energy storage core industries:

Airport Aviation Fuel System

Airport refueling vehicles, underground hydrant dispensers, aviation fuel depots, filter water separator first-stage coalescing filtration for jet fuel/kerosene. It removes emulsified free water and rust, sand particles to guarantee fuel meets aviation safety standard, protecting aircraft engine fuel nozzles from corrosion and blockage.

Oil Depot & Refinery Filtration

Diesel, gasoline, kerosene storage depots, crude oil refinery intermediate liquid filtration; separates free water in bulk oil during tank car unloading and pipeline transportation, reduces tank bottom water sediment and equipment corrosion.

Petrochemical & Light Hydrocarbon Treatment

LPG, benzene, toluene, xylene, low-viscosity turbine hydraulic oil, industrial solvent filtration; FKM rubber option adapts aromatic solvent to avoid seal swelling leakage.

Mobile Fuel Refueling Equipment

Mining site refueling trucks, construction machinery fuel supply stations, marine fuel separators, stable performance under frequent vibration and variable flow conditions.

Core Advantages vs Original FAUDI Filter

Basic Compatibility: The overall dimensions, end cap structure and sealing grooves are basically matched with the original FAUDI MIL.4-1422 filter, enabling direct installation for most original filter housings with no major equipment modification.
Stable OEM-level Performance: Adopts optimized gradient glass fiber media and hydrophobic coating, with dirt holding capacity reaching the original standard, maintaining long-term stable aviation-grade water and impurity removal performance.
Longer Service Life: Effectively slows down differential pressure rise rate under continuous operation, with a longer service cycle than ordinary generic replacement filters.
Flexible Material Matching: Supports free switching between NBR and FKM sealing materials to adapt to different fuels and chemical media, solving the single configuration limitation of original filters.
Customization Support: Can customize filter media thickness and surface printing according to actual working conditions to meet personalized filtration demands.
Cost & Delivery Advantages: No long overseas delivery cycle of original imported parts; standard models are in stock for same-day delivery, customized products take 3–7 working days, greatly reducing procurement costs.

Installation and Daily Maintenance Guidelines

1. Pre-installation Preparation: Thoroughly clean dirt and accumulated water inside the filter housing to avoid secondary pollution to the new filter element. 2. Installation Inspection: Check the size, sealing position and flow direction of the filter to confirm basic matching with original equipment; avoid forced installation for slight assembly tolerance. 3. Regular Inspection: Inspect the operating differential pressure of the filter every week to monitor working status in real time. 4. Timely Replacement: Replace the filter when the differential pressure reaches 1.0 bar; appropriately shorten the replacement cycle for high-impurity and high-water content oil media. 5. Daily Maintenance: Standardize operation and maintenance to prevent pressure surge, ensure stable filtration efficiency, and extend the service life of filter elements and supporting equipment.
