Air intake filter

製品・サービス説明

Donaldson air filters are designed to efficiently remove dust, dirt, and other contaminants from the air entering engines and machinery, helping maintain equipment performance and extend service life. In environments where construction and industrial equipment operate, airborne contaminants such as sand, dust, and fine particles are common. If these contaminants enter the engine, they can cause accelerated wear, reduced efficiency, and potential damage to critical components. For this reason, reliable air filtration is essential to protect equipment and maintain stable operation. Drawing on decades of filtration expertise, Donaldson develops air filters that deliver consistent and reliable filtration performance even in harsh operating conditions.

The featured technology, ArmorSeal, is a next-generation air filtration innovation developed by Donaldson. It incorporates an advanced sealing structure that significantly improves the sealing performance between the filter and the housing. In demanding environments where vibration, shock, and temperature changes are common, maintaining a reliable seal is critical. ArmorSeal is designed to maintain high sealing integrity even under these severe conditions, reducing the risk of unfiltered air entering the system. By preventing air bypass, the filter can deliver its full filtration performance and provide more effective protection for engines and equipment.

Hydraulic Filter

製品・サービス説明

One of the most important factors determining the performance of a hydraulic filter is the filter media. Donaldson’s Alfa-Web is a high-performance filter media developed for hydraulic systems using advanced nanofiber technology. It is designed to efficiently capture fine contaminants while maintaining stable filtration performance. In hydraulic systems, even very small particles can cause wear or damage to precision components such as pumps, valves, and actuators. This contamination can reduce system efficiency, shorten equipment life, and lead to unexpected maintenance or downtime. Therefore, reliable and highly efficient filtration is essential for maintaining the performance and durability of hydraulic equipment.

Alfa-Web features a unique structure in which an extremely fine nanofiber layer is applied to the surface of the filter media. This nanofiber layer captures very small particles efficiently, delivering higher filtration efficiency compared with conventional media. Because contaminants are trapped primarily on the surface of the media, Alfa-Web promotes surface filtration rather than depth loading. This helps prevent particles from penetrating deep into the media structure, allowing the filter to maintain lower pressure drop and more consistent performance over time. As a result, Alfa-Web can contribute to longer filter life and improved protection of hydraulic systems.

Donaldson’s Alfa-Web media is designed to perform reliably even in demanding operating environments such as construction and industrial machinery. By providing superior contamination control, it helps protect critical hydraulic components, reduce maintenance costs, and support stable machine operation. Alfa-Web represents Donaldson’s continued commitment to advancing filtration technology and delivering high-performance solutions for modern hydraulic systems.

Liquid Filter

製品・サービス説明

Donaldson fuel filters are designed to protect engines and fuel systems by removing contaminants and water from fuel before it reaches critical components. As modern engines increasingly use high-pressure fuel injection systems, effective filtration has become even more important. Even very small particles or trace amounts of water can damage sensitive components such as fuel injectors and pumps, leading to reduced efficiency, increased wear, and costly downtime. To address these challenges, Donaldson has developed advanced fuel filtration media technologies that provide high filtration efficiency and reliable system protection.

Synteq XP is a high-performance fuel filter media developed using Donaldson’s proprietary synthetic fiber technology. It is designed to capture fine particles efficiently while maintaining stable filtration performance throughout the filter’s service life. Its engineered fiber structure offers high contaminant-holding capacity, allowing the filter to retain more particles while maintaining stable fuel flow. This helps extend service intervals and improves protection of critical fuel system components.

Synteq Dry is a media technology developed to efficiently separate and remove water from fuel. Water contamination can cause corrosion, microbial growth, and damage to fuel system components. Synteq Dry provides excellent water separation performance, helping ensure that cleaner and drier fuel reaches the engine. This contributes to improved engine reliability and stable operation.

Together, Synteq XP and Synteq Dry represent Donaldson’s advanced fuel filtration technologies. By combining efficient particle removal with reliable water separation, these solutions help protect modern fuel systems, improve equipment reliability, and support stable operation in demanding environments such as construction and industrial machinery.
