Frequently Asked Questions
A hydraulic filter removes solid contaminants such as metal particles, dirt, wear debris and sludge from hydraulic oil. Clean hydraulic oil prevents abrasion and damage to precision components including pumps, valves and cylinders, extends system service life, reduces maintenance costs and minimizes equipment downtim
Hydraulic filters are classified by installation position: suction filters (pump inlet protection), return line filters (system return oil filtration) and high-pressure filters (downstream of pump for component protection).
They are also available as complete filter assemblies or replaceable filter elements, with different filtration ratings for different system requirements.
Replacement intervals depend on operating environment and system type.
For standard construction machinery, return line filters are typically replaced every 500–1000 operating hours, and high-pressure filters every 1000–2000 hours.
In dusty, mining or heavy-duty environments, more frequent replacement is required. We recommend following equipment manufacturer guidelines.
Filtration rating indicates the size of particles the filter can effectively remove, measured in microns (μm). Common ratings are 3μm, 5μm, 10μm and 25μm.
The required rating depends on the sensitivity of system components — high-precision proportional valve systems require finer filtration than simple heavy-duty hydraulic circuits.
For standard stock hydraulic filter models, our MOQ starts at 20-50 pieces per model.
For custom OEM branded or custom specification orders, the MOQ starts at 300-500 pieces per model. We support mixed model orders to fill full containers for optimized shipping cost.
We could offer samples of standard production models for quality and dimensional evaluation, with the buyer covering express shipping costs. Custom prototype samples require a tooling and sample fee, which will be credited against your first bulk order.
