The FAUDI K.4-1093 is a high-precision aviation-grade coalescer element, widely used in fuel separator systems for aviation fuel depots, petrochemical terminals, and low-viscosity hydrocarbon fluid purification. Renowned for stable water coalescence and solid contamination interception performance, the original FAUDI cartridge is limited by high import prices and long overseas delivery cycles. Our K.4-1093 replacement coalescer provides a fully drop-in, 1:1 interchangeable solution that duplicates all OEM structural designs, installation dimensions and filtration standards. It delivers identical industrial-grade purification performance while greatly reducing procurement and operational costs, becoming a reliable cost-saving alternative for long-term industrial filtration operation and maintenance.
Original FAUDI VS Our K.4-1093 Replacement
Most industrial operators face high operational costs and supply instability when adopting genuine FAUDI K.4-1093 filter elements. Our replacement version achieves full performance equivalence with prominent cost and supply advantages, solving core user pain points:
100% Performance Consistency: Completely consistent with original FAUDI products in filtration precision, water separation effect, dirt holding capacity and pressure resistance. It can effectively remove pipeline rust, fine catalyst impurities and emulsified water from various hydrocarbon fluids, ensuring the final fuel cleanliness fully meets OEM and aviation industry qualification standards.
Zero-Modification Compatibility: Fully replicates the original size, end cap structure, sealing interface and installation stroke. It can be directly installed into original FAUDI filter housings and separation skids without any equipment modification, avoiding installation errors, leakage risks and extra engineering costs.
Remarkable Cost Reduction: Factory direct sales eliminate import tariffs and multi-level distributor markups. The overall procurement cost is reduced by 35%–60% compared with genuine FAUDI elements, effectively cutting annual consumable expenditure for enterprises with large filter consumption.
Fast & Stable Supply: Original imported FAUDI filters require 30–45 days of long lead time; our factory has sufficient stock and mass production capacity, with bulk orders delivered within 7–10 working days, preventing production shutdown losses caused by supply delays.
Reliable After-Sales Service: Equipped with 12-month factory warranty, consistent with original brand service standards, with faster after-sales response and technical support.

Complete Factory Testing Process & Quality Certification System
Raw Material Incoming Inspection: Batch sampling tests on glass fiber media, sealing gaskets and structural accessories to verify hydrophobicity, corrosion resistance and structural firmness, eliminating unqualified materials from the source.
Semi-Finished Product Inspection: Check pleat uniformity, media bonding tightness and structural flatness to prevent fiber shedding and structural deformation during high-flow continuous operation.
Finished Product Performance Test: Conduct full-pressure leakage test, solid particle interception test and emulsified water coalescence efficiency test to ensure all technical indicators fully meet OEM and EI industry standards.
Durability Simulation Test: Simulate long-term temperature cycling and pressure fluctuation working conditions to verify structural stability and service life under harsh industrial environments.
Standard Quality Certification: All products comply with ISO9001 quality management system certification. Complete test reports and qualification documents are available for batch orders to support customer factory inspection and project acceptance.
Aviation Fuel Facilities: Airport fuel storage depots, refueling truck filtration systems and aviation hydrant pipeline separators to ensure jet fuel purity and protect aircraft engine components.
Petrochemical Terminals: Gasoline, diesel and LPG purification, as well as aromatic solvent filtration, removing emulsified water and fine chemical impurities to improve finished fuel quality.
Power Generation Industry: Gas turbine and industrial generator fuel pretreatment, stabilizing combustion efficiency and extending the service life of turbine nozzles and blades.
Marine & Offshore Systems: Offshore platform fuel supply equipment and ship diesel pre-separation systems, adapting to fluctuating marine temperature and pressure working conditions.
