When considering a Schroeder process filter for your application, you can select from the three basic designs
1.	Inline Filters (simplex and duplex) for finer filtration Simplex requires the filter be taken out of service to effect element changes Duplex filters allow running changes of elements
2.	Basket Filters (simplex and duplex) for coarse filtration Simplex requires the filter be taken out of service to effect element changes Duplex filters allow running changes of elements
3.	Automated / Self-Cleaning Filters for all filtration requirements with water as the filtered medium Virtually maintenance free filter is PLC controlled and continuously “on line.”
There are eight (8) main considerations in choosing the proper filter housing
1.	Fluid Compatibility – How will the materials of construction and seals for both the housing and element withstand the process medium? Materials of Construction Housing Construction – Base Materials – see Technical Data section for more detailed information Seals – see Technical Data section for more detail on seals and compatibility Filter Elements – see Element Selection Guide (pdf) and Technical Data section for more detailed information
2.	Pressure Rating – The maximum sustainable working pressure of the system.
3.	Pressure Drop (loss) – How important is maintaining pressure rating and heat generation in the system?
4.	Process Connection Size – The process piping and specific requirements of the system determine these criteria.
5.	Filter Element Options – What is the desired pore size of the element and the requirements of the system (see Filter Element Selection)
6.	Overall Efficiency – based on filter element selection
7.	Accessories
8.	Economic Considerations

The fundamentals of filter element selection will focus upon the type of fluid you are filtering, and what filtration level you require.

In some cases, basic filtration is required when coarse materials in the fluid are to be removed. In other instances, extremely fine filtration may be needed for the specific process or equipment within the system.

There are two classes of Schroeder Industries LLC filter elements
1. Reusable
2. Disposable

Once again, Schroeder Industries LLC sets the standard for environmental stewardship with reusable filter elements. When choosing the proper filter element, you now have a choice not only based on filtration requirements, but on the materials of construction and the possibility of environmental impact. As you begin the selection process for filters and filter elements, you will be able to add to your criteria whether a disposable or reusable element suits your application best. Consideration should be given to all of the environmental consequences, and we urge you to contact our application engineers during the selection process.

Reusable Elements
Designed to allow the user to replenish the media through cleaning, these elements utilize metallic media for long-term usage. Re-usable elements are easily cleaned by the procedures described in the Technical Data section of this document. In some cases, “intelligence” is built into the filter housing and through an internal process, the filter performs the cleaning process itself. This feature is the benchmark of the SC products.

Disposable Elements
Schroeder disposable elements are manufactured of multi-layer synthetic microglass, engineered for high efficiency, large capacity, low pressure drop and excellent durability characteristics. The layered construction is unique, as each layer performs a specific function. This is the ultimate filter media for maximum cleanliness in your system.

The graphical representation on the following page demonstrates five differing element types and their corresponding micronic range. This is critical to selecting the level of cleaning required in your system. It is important to select the medium that is appropriate to your application. There are dangers in both under-sizing and over-sizing of the element. Selecting a pore size too large can have adverse effects on your process or the equipment you are trying to protect. Selecting a pore size smaller than your requirements will ad unnecessary protection and introduce pressure drop and heat that may affect your process. If you are unsure of your specific requirements, please contact our Application
Engineers for assistance.
