Maintaining the integrity of a hydraulic system requires a deep understanding of the specific components that keep it running. Filtration is not a one size fits all solution, as each stage of a fluid power system presents unique challenges. Choosing the wrong media or placement can lead to pump cavitation, component wear, or total system failure.

Our team specializes in engineering precision components that ensure maximum uptime and operational efficiency for your fleet, from suction filters to can filters, air filters and more. You can trust DOMS Incorporated to deliver the reliability your heavy duty equipment deserves. Contact us today to learn more!
Basic Qualities of Common Filter Types
Suction Filters
These components are specifically designed to remove fine contaminants from the suction line of a hydraulic system. They typically capture solid particulates and pollutants that are smaller than 50 microns in size. By cleaning the fluid before it reaches the pump, suction filters provide a critical line of defense. Our designs feature a rounded root and crest pleat that maximizes the available surface area for better flow.
Can Filters
These units are often utilized for their versatility and ease of installation within various fluid systems. Many operators prefer can filters when they need a self contained unit that protects against external debris. They are common in both industrial and mobile applications where space and accessibility are primary concerns. Using high quality can filters ensures that your system remains sealed and free from environmental pollutants.
Hydraulic Filters
Effective hydraulic filters are essential for maintaining the cleanliness of the fluid that powers your actuators and motors. They are strategically placed throughout the system to catch wear debris generated by moving parts. Without reliable hydraulic filters, these small metal shavings can cause significant internal damage over time. We offer these in various configurations to handle different pressure levels and flow requirements across your machinery.
Air Filters
Air filters are used to boost the quality of air in systems like motors and air compressors. They are designed with high air permeability to prevent dangerous pressure differentials and contamination buildup. You can choose from synthetic or stainless steel construction depending on the harshness of your environment. These filters ensure that the air entering your equipment is clean and free of abrasive particles.
Spin-On Filters
For systems that require quick and easy maintenance, spin-on filters are an excellent and economical choice. They are designed for direct in-line mounting, which simplifies the replacement process and reduces housekeeping requirements. These are ideal for low pressure systems like cooling circuits and fuel transfer lines. Their design ensures that you can perform field maintenance without specialized tools or extensive downtime.
Reservoir Breather Filters
As fluid levels change within a tank, reservoir breather filters allow the system to breathe while blocking moisture and dust. They are mounted on the tank or reservoir to ensure that only clean air enters the headspace. This prevents the ingestion of airborne contaminants that could otherwise degrade the hydraulic fluid. These breathers are a simple yet vital component for extending the life of your entire hydraulic circuit.
How to Choose the Right Filter
Selecting the proper filtration starts with understanding the operating pressure and flow rate of your specific application. You must also consider the type of fluid being used and the environment where the machine operates. A filter that works well in a controlled factory setting may fail in a dusty mining operation. Always evaluate the micron rating to ensure the media can capture the specific types of debris common to your industry.
Determining the bypass valve settings is another critical step in your selection process. If the pressure drop becomes too high, the fluid might bypass the media entirely to prevent housing rupture. This means your suction filters or return line units must be sized correctly to handle cold starts. Proper sizing ensures that your hydraulic filters protect the system even during fluctuating temperature conditions.
