Protecting Systems from Contaminants and Moisture: The Essential Role of Breather Filters

Breather filters are vital for maintaining the health of hydraulic systems by ensuring that only clean air enters the tank. They play a critical role in protecting machinery from contaminants like dust, dirt, and moisture, which can lead to expensive breakdowns.

Hengst’s breather filters are designed to promote long-term system performance by preventing harmful particles from entering the tank and keeping internal components safe.

The Challenges in Protecting Systems from Contaminants

When contaminants such as dust, dirt, and moisture enter hydraulic systems, they can create a number of issues:

  • Corrosion and Damage: Moisture can cause rust and deterioration of system components
  • Reduced Efficiency: Dirt and dust can cause seals and valves to wear out faster, affecting the system’s overall performance
  • Pressure Problems: Without proper airflow, the system may suffer from fluctuating pressures, risking internal damage.

These challenges highlight the importance of ensuring that the air entering hydraulic systems isproperly filtered.

A Better Solution: Protecting Systems with Advanced Filtration

Hengst’s breather filters ensure optimal system performance by combining multi-stage filtration, moisture control, and airflow management:

  • Filtration: The filter element traps dust, dirt, and other harmful particles, ensuring only clean air enters the tank.
  • Moisture Control: Certain Hengst breather filters, such as the BFSK model, contain moisture-absorbing materials that prevent water vapor from causing rust and corrosion.
  • Pressure Regulation: By allowing proper airflow, Hengst filters help maintain stable pressure within the tank, protecting internal components.

These features work together to extend equipment lifespan, improve efficiency, and prevent costly breakdowns.
