Filter Housings

Hydrocarbon Filtration Systems has a range of filter vessels available for rental and purchase.

We also provide sizing, design, and fabrication of custom ASME code and non-code filter housings for a broad range of industrial applications.

You can choose from a selection of metals, including carbon steel or 304 and 316 Stainless Steel, all of which are meant to increase corrosion resistance and eliminate the need for expensive coatings and oxidation within the filter vessels.

We also offer a wide range of exterior finishes and interior linings customized specifically for your needs.

Available Filter Housings and Filter Vessels: 

Our standard Bag Filter Housings are made in number 2 and number 4 Type Industrial Bag Filters, which are 7" in diameter by 32" in length and 4" in diameter by 12" in length, respectively.

We specialize in cartridge and bag vessels for many different processes and kidney loop filtration applications.

Our primary cartridge filter housings range in size from 4" in diameter by 20" in length (the 420 series) to 6" in diameter by 40" in length (the 640 series) and come in a number of housing configuration options including single, dual, tri, quad, 6, 8, 12, and 18, all of which help to further optimize filtration performance.

Many ports are available for filter housings, but we prefer Code 61 style O-ring flanges because they offer superior sealing protection from leaks. O-rings are a far superior design when compared to flat or gasket seals, but we still offer other option such as ASME Flanges and NPT Ports.

We also like to include differential pressure gauges on our filter housings so that users know when to change filter elements.

A question we are commonly asked by customers is how long a filter will last.

The best answer we can give is that it all depends on how much contamination is present in the fluid you are trying to filter.

It is important to remember that a differential pressure gauge will show you an amount based only on differential pressure, and when using a new filter, the pressure will present very low. As contamination begins to accumulate, the differential pressure will increase.

We typically recommend that bag filters be changed at 20 pounds per square inch differential (PSID) and cartridge filters at around 40 PSID.

Another great option to include on a filter vessel is a pressure gauge.

Let's say, for example, your main pump pressure is at 100 PSI. In that case, you would want a compound pressure gauge that can go up to 160 PSI. This way, you have a buffer in case the filter vessel becomes dead headed where the max pump pressure is subjected to the filter vessel.

We would also recommend a vent and drain valve for all filter vessels. A vent valve is used to purge off any air or gasses present in the filter as it fills with oil. Note that these vents are generally located at the highest point of the filter vessel whereas drain valves are located on the bottom of the vessel.

Another great feature to include is a small ¼" upstream and downstream sample port valve. By taking samples of both upstream and downstream ports, you can determine the overall efficiency of the filter element.

Keep in mind that as a filter element loads, it will indicate noticeable different pressures on the differential pressure gauge and will show much less particle upstream than downstream.

All this means is that the filter is working by taking particle count samples from both upstream and downstream locations and you are given a positive confirmation of the effectiveness of your filtration application.

Filter Vessels can be used as an inline filtration process, also known as Kidney Loop Filtration, where fluids are transferred and filtered between a reservoir and filter housing. This process is very similar to how your kidneys continuously filter blood throughout your body. After 10 to 20 passes, particulate contamination generally meets or exceeds new oil cleanliness results.

Many of our filter vessels are based on the following criteria:

  • Vertical configuration
  • Materials of construction: Carbon Steel, 304/L and 316/L Stainless Steel, Duplex Stainless Steel and other Stainless alloys.
  • ASME code and additional standards or non-code design
  • Temperature and pressure requirements
  • Process flow rate
  • Physical and chemical properties of the process fluid
  • Preferred Inlet/Outlet Nozzles Sizes
  • Flanged, NPT, BSPT, SAE connections are available.
  • Closure styles, i.e. quick-opening, swing-bolt, and flanged
  • Non Destructive exemption requirement such as RT, UT, PT, MT, WFMT, PMI, Hardness, PWHT and ferrite level testing.
  • Supplemental nozzles: vents, delta P ports, clean drains, dirty drains, sample ports etc.
  • Cover Davit System Mechanical or Hydraulic
  • Internals (baskets, hold down plates, etc.)
  • Finishing's for exterior and interior lining available: Electropolishing, Passivation, Hot-Dip Galvanizing, Nickel Plating, Painting, Powder Coating, Media/Abrasive Blasting, Zinc Plating, Teflon® Coating, Rubber Coating, Epoxy Coating, Thermal Spray Aluminum, and Fireproofing.
  • Supported File Formats/Software AutoCAD (DWG, DWZ) IGES, STP, JPG/JEPG, PDF.
