Filter elements are efficient and fully utilized only if their capacity to remove contaminants is fully-exploited. This, can be achieved by use of clogging indicators mounted onto filter assemblies/housings.

Knowing when your filter element needs to be changed is essential. Changing it early could result in the underutilization of filter elements, while changing it late could lead to the system operating in Bypass mode, wherein contaminated oil is allowed into the system.

The guarantee of operational safety for a system and the efficient utilization of a filter element can only be ensured if there is an installed effective filter clogging indicator.

As the hydraulic oil flows through the filter, dirt particle retention by the filter element increases, which leads to a loss of pressure in the filter housing. As this pressure drop builds up, it will reach a particular limit value, thereby triggering the hydraulic filter clogging indicator alarm. This indicates an imminent element replacement.

These indicators are designed for use on a wide range of filters and are suitable for competitive interchange. Available options to indicate filter elements in use condition, are visual, electrical, combined visual-electrical, and electronic feedback. These facilitate effective maintenance and assists to ensure your hydraulic systems, machine / mobile/industrial machines are protected from particulate contamination.

Some users save costs, use filters without clogging indicators and instead prefer to change or clean the elements as per a specified schedule or a set number of operating hours. However, this involves some risk.

Advantages of Fitting a Clogging Indicators

  • Gives a correct indication of element clogging to its max capacity, the benefit of full product utilization
  • The operator is no longer is required to estimate when the element is clogged
  • Eliminates the cost of changing the element too early
  • Can be fitted to any standard filter at any time without any difficulty, simply need to screw it in.

Available Types and Features of Clogging Indicators:

  • Visual clogging indicator: Manual Reset or Auto reset feature
  • Electrical clogging indicator: With electrical output signal
  • Electronic clogging indicator: Pressure switch with electronic output signal with stages of clogging
  • Combined Visual + Electrical type
  • Wide range of vacuum pressure range for suction applications
  • Wide range of normal pressure range from 1 bar to 8 bar depending on application requirements.
