Guide to High-Pressure Filters

Guide to High-Pressure Filters

Jump To: 

High-pressure filters are essential for your system. Without them, a component can quickly be become less effective or damaged due to obstructions and an otherwise contaminated environment. Different high-pressure filters serve different purposes, but there is a wide variety available from Chase Filters ensuring your filtration system will work as well as it possibly can.

What Is a High-Pressure Filter?

High-pressure filters are most often used in hydraulic systems. They are designed to hold up against the maximum pressure the system can put out and are sized based on the flow rate of that system. They provide protection to sensitive components that are working downstream of the filters. Though they are located upstream from those components, they are downstream of the system pump.

How High-Pressure Filters Work

High-pressure filters work when fluid is pushed into the inlet of the filter. This allows the filter to block the contaminants and filter them out of the system.

This process is usually very fast because of the high pressure. Because it is so fast, it is important to keep an eye on your differential pressure indicator. If that number rises, there could be dirt clogging the filter element that means the element needs to be changed out or cleaned.

The high-pressure filter should have an indicator or a delta P device to read the inlet and outlet pressure thru the filter.

What Is a High-Pressure Filter Element?

What Is a High-Pressure Filter Element?

A high-pressure filter element protects the components against fluid containment and extends their working life. These can also be called cartridges. Elements can be customized to fit the needs of the high-pressure filter you have or need. The elements have low differential pressures, which keeps you from needing to clean or changing the filter frequently, reducing maintenance costs.

There are different types of high-pressure elements — specifically a high-pressure micro glass hydraulic filter element, fiber metal felt and a stainless steel filter element. The Chase micro glass elements are special design with any extra layer of support and drainage media. The stainless elements are all 304 stainless, with 4,500 – PSID capabilities and all welded construction.   The fiber metal felt elements are multi-layer and are rated at beta 1,000 down to 3 micron absolute.   The element you choose will be based on your system’s requirements, which will also determine how it is mounted, its dimensions and micron ratings.

Types of High-Pressure Filters

There are many types of high-pressure filters, each designed to fit specific commercial and industrial filtration needs.

51 Series

The 51 Series T-Type hydraulic filters are rated at 6,000 PSI in stainless steel or 5,000 PSI Operating Aluminum. All three types of elements are available in the 51 Series.  This series also offers visual indicators, bypass valves, delta P ports and bowl drains.  Port sizes range from ¼ to 1 ½ inch.  These filters are designed to ensure rust, scale, dirt and other substances you don’t want in your system are cleared out.

52 Series

The 52 Series T-Type high-pressure filter are intended to remove particles that can harm your system, increase maintenance cost and result in costly downtime. These could be particles of rust, dirt, water and scale. The 52 Series filter comes made in a variety of materials such as 17-4, 316 or 303 The elements are available stainless steel, micro-glass and fiber metal felt. The 52 series is available in ports sizes from ¼ to ¾ of inch in NPT, MP and HP threads.

Industries that use both the 51 and 52 Series high-pressure filter include the following:

  • Automotive
  • Energy
  • CNG
  • Extraction
  • Mining
  • Petrochemical
  • Hydrogen
  • Aerospace
  • Helium
  • Oil field services

50 Series Tee-Type Filters

High-pressure oxygen systems benefit from using the 50 Series Tee-Type filters. They work by reducing contamination levels and the risk of particle-related damage to critical parts of your system. The 50 Series filter’s design for oxygen makes it easy to remove and replace the 10-micron sintered bronze element. The filter offers a dependable and economical option for your system.

These filters are often used in the following industries:

  • Laser Cutting
  • Medical
  • Aerospace
  • Pharmaceutical
  • Space flight
  • Breathing air
  • Testing laboratory
  • Gas plants
  • Mining
  • Oil and gas
  • Test facilities
  • Navy Diving
  • Aerospace

25 Series Threaded Mini In-Line Filters

The 25 Series high-pressure threaded in-line filter is similar to the 20 Series but has a 10-micron sintered replaceable element with a fluted design. The fluted design allows it to lock in debris, lower pressure drop and increase the surface area so your filter works to its full potential.

These filters serve specific applications, including:

  • Space flight
  • Breathing air
  • Testing laboratory
  • Booster pumps
  • Laser cutting
  • Breathing apparatus for the mining industry

21 Series

The 21 Series mini-inline industrial fluid filters are economical and lightweight, featuring stainless steel wire mesh discs. These discs allow for a higher and more active filtration area.

This filter works in a variety of industries and is best for these specific applications: Instrumentation, gage protection, Aerospace

  • Flow meters
  • Case drains
  • Spray Nozzles
  • Pneumatic systems
  • Robotics
  • Hydraulic systems

31 Series

The 31 Series in-line filters are great for filtering the oil and gas streams in industrial and aerospace equipment, allowing them to perform to the best of their abilities. They are best used for removing the following contaminants:

  • Fiber
  • Iron
  • Dust
  • Dirt
  • Sand
  • Silt
  • Rust
  • Metal shavings

57 Series High-Pressure Compressed Gas Filters

The 57 Series filters are coalescing gas filters that withstand high-pressure compressed gas using coalescing filtration techniques. This filter removes 95% of 0.01 microns, effectively eliminating oils, water and other liquid from your filtration system.

High-Pressure Filter Applications

High-pressure filters are best suited to filter solids under high pressure compared to other filters. The point of a high-pressure filter is to protect the components and instrumentation downstream from contamination levels. Each system has a recommended cleanliness target that is important to keep in mind, as some contamination is inevitable. Having a high-pressure filter in your system is incredibly important to keep components from destructive failure across all applications.
