A Filter Element is the center component in a filtration system, where the real filtration occurs. The element and filter medium utilized determine crucial filter properties such as retention capacity, dirt holding capacity, and pressure loss. A hydraulic filter element is a component that is built into its corresponding housing to reduce fluid pollution to the required level, which is then maintained and stabilized during the system’s operation.
Why Are Hydraulic Filter Elements Important?
A hydraulic filter eliminates impurities from hydraulic oil, such as dirt, debris, and other pollutants that can cause wear and tear on hydraulic components. They are put in the hydraulic circuit to safeguard hydraulic components by catching impurities before they can cause harm to the system.
Modern high-pressure hydraulic systems with components constructed to tighter tolerances are vulnerable to a variety of contaminants. Contaminants can lead to premature wear of interior surfaces. They also cause leaks and obstruct the flow pathways. As a result, every hydraulic system should have an effective and properly designed filtration system to separate particulate matter of a specific size or larger from the system fluid. They should be installed at strategic positions throughout the hydraulic circuit to efficiently control pollution.
Types of Hydraulic Filter Elements
There are several varieties of hydraulic filters, and they are frequently classed based on where they are intended to be installed in the hydraulic system. The most often used hydraulic filter types are:
1. In-Line Filters
Placed directly on the fluid line, may be suction side (before the pump) or pressure side (after the pump but before the valves and cylinders); intake, exit, and media are aligned.
2. Off-Line Filters
Consists of a separate pump and filter connected directly to the reservoir, commonly used to complement main system filters.
3. Tank Filters
May be placed on or within the fluid reservoir, with an accessible head on the tank’s exterior for quick access and media replenishment.
4. Spin Filters
On consists of an in-line head screwed onto. Threaded canister, easy to install, and inexpensive.
5. Return Line Filters
Filter is installed directly on the return line; it can also be spin-on, in-line, or tank mounted.
6. Duplex Filters
A valve/filter combination that allows flow to two distinct filters while maintaining flow during filter maintenance.
