Hydraulic filters are sized based on the flow passing through them at an acceptable pressure drop. Hydraulic filters protect your hydraulic system components from damage due to contamination of oils or other hydraulic fluid in use caused by particles. A hydraulic filter helps to remove these particles and clean the oil on a continuous basis. The performance for every hydraulic filter is measured by its contamination removal efficiency,
i.e. high dirt-holding capacities. The hydraulic filters between pump and actuators are referred to as pressure filters and the hydraulic filters between the actuators and tanks are low pressure or return line filters.
- Housing and filter assemblies have built-in casings or enclosures that cover and/or protect the filter assembly.
- Filter elements or cartridges are porous devices that perform the actual process of filtration. A filter element uses pleated or mesh construction and can be disposable (one-time use) or reusable.
- The filter is mounted on top of or on the side of the reservoir.
- Magnetic filters are designed to trip ferrous particles.
- Products filter particles and contaminants from coolants.
- Products filter particles and contaminants from hydraulic fluid supply lines.
- This is the maximum pressure at which the filter is designed to operate.
