Filler and Breather Filter

Filler and Breather Filters reliably protect hydraulic systems against dirt, dust, and moisture, thus making a crucial contribution to the cleanliness of the hydraulic fluid. During filling, they prevent the ingress of particles, while breather filters enable a controlled air exchange and clean the intake air. Learn more...

Filler and Breather Filters – Frequently Asked Questions

What are filler and breather filters in hydraulic systems?

Filler and breather filters are essential components in hydraulic systems. They prevent contaminants from entering the reservoir and thus the entire hydraulic system during filling or through the necessary air exchange. This preserves the cleanliness of the hydraulic fluid and extends the service life and efficiency of the system.

What is the main purpose of filler filters?

Filler filters are located at the filler neck of the hydraulic reservoir and prevent coarse contaminants and dirt particles from entering the tank during filling. They ensure that only cleaned fluid is fed into the hydraulic system.

What is the function of breather filters?

Breather filters allow the necessary pressure and air compensation in the reservoir caused by temperature changes or movements of hydraulic cylinders. At the same time, they prevent the ingress of dust, dirt, and moisture from the ambient air. Modern breather filters are often equipped with desiccants, check valves, and splash protection to additionally prevent oil loss and moisture ingress.

What are the main differences between filler and breather filters?

  • Filler filters: Protect during tank filling by filtering the fluid from dirt particles.
  • Breather filters: Protect during operation by cleaning the intake air and preventing moisture and dirt from entering the system.

What materials are filler and breather filters typically made of and how is the size determined?

The filter elements are usually made of durable filter media such as plastic or polyurethane foam (e.g., 10 µm) in combination with wire or steel baskets for stabilization. The housings are manufactured from steel, aluminum, or plastic. The size is determined by the maximum oil or air flow rate to be filtered as well as the environmental conditions of the hydraulic system.

In which areas are filler and breather filters used?

They are used in mobile and stationary hydraulic systems, such as in agricultural and construction machinery, industrial equipment, cranes, and vehicle hydraulics. Wherever hydraulic systems need to be protected from contamination from the surrounding air, filler and breather filters are indispensable.

What advantages do filler and breather filters offer for hydraulic systems?

  • Protection against dirt and moisture
  • Extended service life of hydraulic components
  • Prevention of malfunctions and system failures
  • Preservation of oil cleanliness and quality
  • Cost reduction through lower maintenance requirements

How are these filters maintained and selected?

Filler and breather filters are usually installed as screw-in filters or with quick-release couplings directly on the reservoir. Maintenance includes regular visual inspections, cleaning or replacement of filter elements, and checking housings and seals. Selection is based on criteria such as flow rate, filtration rating, environmental conditions, and manufacturer recommendations. Proper design is essential to ensure system reliability and service life.
