Filtry.org supplies hydraulic filters for PM industrial machines from trusted manufacturers: HIFI Filter, SF Filter and PZL Sędziszów.

The role of hydraulic filters is to protect key components — the hydraulic filter maintains hydraulic oil cleanliness, protecting pumps and proportional valves. Replacement every 500-1,000 engine hours is fundamental to proper PM industrial machines maintenance.

All hydraulic filters for PM available at Filtry.org include cross-reference numbers and full technical documentation.

Frequently asked questions

How often should hydraulic filters be changed?

Every 500-1,000 engine hours or as indicated by the differential-pressure sensor. Also replace after every hydraulic failure, oil change or pump repair.

What is the difference between pressure-line and return-line filters?

The pressure filter protects valves and hydraulic motors at 200-400 bar. The return filter cleans oil flowing back to the reservoir at low pressure. Both are essential.

What does ISO 4406 oil cleanliness class mean?

ISO 4406 specifies the number of particles larger than 4, 6 and 14 um per millilitre of oil. A typical servo-hydraulic system requires class 16/14/11 or better.
