Because high durability stainless steel filters have a tremendous amount of adsorptive stainless steel surface area the surface will adsorb or capture H2S, mercaptans, and other sulfur compounds; making analyzers like CEMS (continuous emission monitors) ineffective. Sulfur adsorption can hold up accurate CEMS measurements by up to 90 minutes or more.
SilcoNert® 2000 gives the ultimate passivation treatment for stainless steel surfaces. This is not a consideration with our disposable filter media as these offer an inert surface, however, the stainless steel filter elements must be considered for treatment with SilcoNert® to create a completely inert flow path. SilcoNert® technology ensures the treatment penetrates even the smallest pores in the surface of the filter housing, and stainless steel elements. This should be used when analyzing in the parts-per-billion levels of sulfur compounds & mercury. Contamination by moisture is also reduced and overall sample system performance is improved.
Any stainless steel filters supplied by United Filtration Systems/Headline Filters can be SilcoNert® 2000 treated with a estimated delivery of 2-3 weeks. We have many customers that request our H series of heatable housings for automotive emission testing be SilcoNert® coated for the above reasons, but also because the coating helps prevent galling and makes element removal easier. The SilcoNert® creates a “smooth” surface which eliminates element sticking do to the constant high temperature operations.

Borosilicate glass microfibers are considered to be the ideal filter media available for the coalescing of liquid aerosols. This material is neither liquid adsorbent nor absorbent and consequently, is superior for retaining its original properties while in service. The C-Type element has a two-layer structure, an inner particle capture-layer and an outer drainage layer. Liquid droplets remain mobile once captured and travel through the fine-pored captured-layer, along the intersecting microfibers, growing in size as they progress. These coalesced droplets are transferred to the large-pored drainage-layer, from where they drain by gravity into the filter bowl.
The filter housing must be piped so that the gas stream enters port 2 (deep port) and exits port 1 (shallow port) so that the captured liquid can pass through the element (coalesce) and drop into the drain. Do not pipe backwards or the coalesced liquid will pass back into the system. Liquid collected in the filter bowl can be removed by a manual or fully automatic drain.
Metallic, plastic, paper (pleated), and baffle units do not exhibit the same natural properties as borosilicate glass microfibers, i.e. metallic and plastic elements do not have fibers to turn liquid contamination into droplet form. A film builds up on these elements, thus increasing ∆p and reducing long-term efficiency. Paper elements have fibers but tend to retain the water droplets like a sponge and there again, ∆p increases and reduces long-term efficiency. Baffles are fairly efficient at removing bulk contamination. Unfortunately, most contamination in compressed air lines is in the form of fine mist.
Compressed air, even from a new installation, is a heavily contaminated product. Dirt is ingested through the compressor inlet, oil is carried over from the piston, and water condenses out at the higher air pressure. The demand for more sophisticated and more reliable pneumatic systems can only be met by ultra-clean compressed air. Ultra-clean compressed air is most conveniently produced in the production plant by the installation of a well-designed Coalescing Filtration System. This system will remove essentially all solid and liquid contamination, with minimum maintenance and low operating costs. Our Coalescing Filters remove up to 99.99% of solid and liquid particles down to 0.01 micron, producing truly clean compressed air.
The C-type elements are completely self-supporting and are sealed into the filter housing simply by tightening a retaining nut. No end caps, gasketing materials or support cores for required. At element change only the filtering material itself is discarded, and this complete disposability keeps replacement element costs down.
The coalescing filters are designed to have an initial dry pressure drop of less than 2 psi. Thereafter the pressure drop will increase very slowly as solid particles are captured and retained in the captured-layer of the element. UFS recommends changing the filter element when the pressure drop reaches 10 psi. The optional differential pressure indicator will give a visual warning of the need to change the filter element.

Our Stainless Steel elements offer excellent chemical resistance and maximum differential pressure drop ratings. Try them in your most demanding applications.
Our Stainless Steel elements are recommended for filtration of heavily contaminated gases, liquids, polymers, and steam, since they are re-cleanable by back-flushing or ultrasonic cleaning. They should also be exclusively used in our Fast Loop Filters, due to the nature of the filter path. Keep in mind that back-flushing and cleaning can only be done for a limited time before the SS elements need to be replaced.
The elements consist of five layers of precision-woven 316L stainless steel mesh formed into cylinders and welded together, along one seam. The five layers offer surface area and depth filtration for removing solids and dropping out liquids. This rigid, durable construction provides precise pore size distribution, flow permeability and lower initial pressure drop than traditional powdered sintered metal elements. As mentioned, the element consists of five layers, with the two outside layers (from both directions) providing pre-filtration, and the inside layer providing the best actual micron rated purification.
Our stainless steel filter elements are made to industry size standards and therefore, fit many other brands of filter housings including Balston® and Finite®.
**Exotic metals including Hastelloy and Monel are also available**

Our wide range of filter housing and element combinations enable us to supply the most suitable product for your application and specifications.
To select the correct filter housing the following information about the application is required:
Questions:
1. Maximum Pressure
2. Maximum Temperature
3. Chemical & Physical Composition of the Stream
Items 1, 2, and 3 will determine the materials of construction of the filter housing, including the element and gaskets. Filter housings are available in a wide variety of standard and exotic materials to ensure there is a product for even the most demanding applications.
4. Type of Filtration Required: Particulate, Coalescing, Bypass, Fast Loop, Liquid-Liquid, Vacuum Inlet or Exhaust
Item 4 will determine the configuration of the housing, one port for inlet filters, two ports for in-line housings and three ports for coalescing, bypass or fast loop housings. Liquid-liquid housings may have variable designs based upon #9. Vacuum inlet filters generally have two ports, whereas, exhaust units have three for coalescing.
5. Contaminant To Be Removed
6. Maximum Flow Rate
7. Line Size And Port Type
8. Level of Filtration Required
9. Relative Importance of Cost, Response Time, Ease of Service, and Interval
Items 5, 6, 7, 8 and 9 will establish the most appropriate size of filter. This is generally a compromise between those factors favoring a small filter (fast response time, smallest space requirement, lowest cost) and those factors favoring a large filter (long service intervals, low pressure drop).
The exact choice will therefore depend on the relative importance of these factors in each particular application.

United Filtration offers a full range of filter assemblies to the Parker Finite H-Series for Compressed Air & Gas. Our assemblies are 100% machined anodized aluminum which provides superior pressure ratings than the Parker Finite H-Series for Compressed Air & Gas.
This design allows us to rate these housings at 500; 1,000; and 1,500 psig. They come standard with NPT threads but also available with SAE threads and we have CRN accreditation for our Canadian customers. Our CS grade of coalescing elements are ideal for compressed natural gas applications because of their robust design and high efficiency rating.
