How do you know when to replace hydraulic filter?
How do you know when to replace hydraulic filter?
Once it reaches a critical level (e.g., 2 bar for a filter that has a 3 bar pressure drop when it is at capacity), the indicator reveals that you need to change the filter. Filters are then changed when the element indicators reveal that the filter is getting near capacity.
How do you change a hydraulic filter?
Changing a Hydraulic Filter: Step-by-Step Instructions
- Lock out the machine.
- Affix filter wrench or strap wrench to the bottom of the filter.
- Turn the wrench to remove the filter.
- Once removed, verify the old seal came out completely and clean the filter head.
- Rub the seal on the new filter with clean oil.
Do hydraulic systems have filters?
Nearly every hydraulic system has a return line filter, which traps particles ingested or generated our in the hydraulic circuit. The return line filter traps particles as they enter the reservoir, providing clean fluid for reintroduction into the system.
When to change oil filter in hydraulic system?
If you change them late – after the filter has gone on bypass, the increase in particles in the oil quietly reduces the service life of every component in the hydraulic system–costing a lot more in the long run. Mistake #2 in “6 Costly Hydraulic Mistakes… And How To Avoid Them!” is changing filters on hours in service.
What happens when you drop a hydraulic filter?
Not only has the filtered contamination entered the system, but it has contaminated the filter itself. In some systems, the pressure drop can cause an extreme increase in pressure upstream of the filter. If that pressure reaches high enough levels and if the filter does not collapse, other components in the system can be seriously damaged.
How are off line filters used in hydraulic conditioning?
Off-line filtration enables continuous, multi-pass filtration at a controlled flow velocity and pressure drop, which results in high filtering efficiency. Filtration rates of two microns or less are possible, and water absorbent filters and heat exchangers can be included in the circuit for total fluid conditioning.
How does return filtration work in a hydraulic system?
For these reasons, return filtration is a feature of most hydraulic systems. Off-line filtration enables continuous, multi-pass filtration at a controlled flow velocity and pressure drop, which results in high filtering efficiency.

Why do I need off line filtration in my hydraulic system?
Off-line filtration is also useful in cleaning a system which has had a spike in contamination. Owners/ operators of hydraulic equipment should examine their equipment and the operations manuals so that they are aware of the types and positions of the filters in their system.
Not only has the filtered contamination entered the system, but it has contaminated the filter itself. In some systems, the pressure drop can cause an extreme increase in pressure upstream of the filter. If that pressure reaches high enough levels and if the filter does not collapse, other components in the system can be seriously damaged.
When to change hydraulic fluid in Mobile and industrial?
In most cases, pressure filters and return filters have a bypass that protects the system when the filter gets clogged or plugged. It allows the oil to go around the filter element and allows the system to run even though it’s not being filtered. Do keep in mind that your system would be running unfiltered with this setup.
