Protecting Components from Rogue Contamination and Debris

Hydraulic, fuel, and pneumatic systems are typically designed to withstand low levels of small-size contaminants but may be damaged by single pieces of large debris. This can result in reduced performance, damage, or even catastrophic system failure. Despite efforts to clean hardware prior to assembly, rogue particles and debris often materialize in fluidic systems. For example, contamination may be introduced prior to operation by either the manufacturing or assembly process.

Contamination may also be generated during operation, such as when meshing gears or friction between two sliding metal components results in erosion. Lastly, debris may be introduced during the maintenance or refilling of an open system. Placing Lee safety screens upstream of critical components and tight passages will help protect your system from the performance issues and damage associated with contamination.

Choose from a wide range of solutions, including different technologies such as woven wire mesh, etched, or drilled safety screen filters. You can also select from a variety of envelopes,retention methods, filtration ratings, materials, and sizes. Our robust designs will allow you to maximize the open area and reduce the pressure drop created by the safety screen.

Providing System Level Filtration

All fluidic systems must have adequate filtration to ensure that the fluid does not contain debris which will impact performance. This may mean using a 4 micron filter made from inert plastics to protect against dust particles entering a medical or scientific analyzer or using a 10 micron high pressure steel filter to protect gaseous satellite propulsion systems.

You can trust Lee components to deliver the performance you need.

We have a wide range of system filtration options, field-proven designs, and industry-specific knowledge to help you find the right solution.

Coarse Level Filtration

You may need coarse level filtration to protect a high flow system from everything from insects entering vent holes to a large piece of metal gear that breaks off during operation. At these times, you’ll want strainers or “rock catchers” that filter large pieces of contamination but have adequate maximum open areas to ensure that they don’t restrict flow to the point of reducing performance. For coarse level filtration over 965 microns, which is used in systems more tolerant of debris, we have robust designs that guarantee the performance you need even in challenging environments.
