Submicronic contaminants in compressed air systems often plug holes and gaps of sensitive pneumatic instruments, wear out seals, erode system parts, reduce the absorptive capacity of desiccant air/gas dehydrators, foul heat transfer surfaces, reduce air-tool efficiency, and corrupt the final products. Resulting in product rejects, lost production time and increased maintenance and expense. For example, trace amounts of submicronic oil can cause significant fish-eye blemishing in automotive finishing operations. Also, water that is left in air lines may freeze during exposure to cold temperatures, decreasing flow or rupturing pipes. Compressor lubricant that is not captured in a coalescing filter will eventually collect in pneumatic components, causing premature component repair or replacement. Environmental concerns may also be raised if oily, compressed air is continually discharged into the environment through a pneumatic muffler.
The client had several process holding tanks in its facility that are unpressurized and have ports for breathing. The Client was concerned about exposing their process tanks to plant air and the possibility of contamination. They installed a Micropure Sterile Tank Vent Filter on every tank on their process line to ensure that sterile air was entering each tank during the breathing process. However, the client found that they were sterilizing the media extremely often to avoid excess backpressure and the media was showing signs of deterioration every time it was checked.
Media type C | Available in grades 4,6,8 or 10 – Air Flow: Inside to Outside |
 | The coalescing element is made with our UNI-CAST construction. Which is composed of an epoxy saturated, borosilicate glass micro-fiber media, this media is used in applications requiring the removal of particulate and liquid contamination. The outer synthetic fabric layer allows quick removal of coalesced liquids. Media type I is fabricated similarly to the C media but includes an additional inner retainer intended for added strength where reverse flow is likely. |
Media type Q | Available in grades 4,6,8 or 10 – Air Flow: Inside to Outside |
 | This coalescing element is composed of an epoxy saturated, borosilicate glass micro-fiber media, and is also made with our unique UNI-CAST construction. This media has a builtin pleated cellulose prefilter as the inner layer. As with the C and I media types, the outer synthetic fabric layer aids in the fast and efficient removal of coalesced liquids. |
Media type D | Available in grades 4,6,8 or 10 – Air Flow: Inside to Outside |
 | Media type D elements are composed of a microglass coalescer, utilize a unique high temperature UNI-CAST formulation, however they are surrounded by inner and outer diameter metal retainers. These metal retainers, coupled with a glass drain layer, make this an extremely strong element designed to remove both solid and liquid contaminants at higher temperatures. |
Media type 7CVP or ME | Only available in 1¼” NPT port size housings and larger |
 | Finite’s 7CVP media type has two filter layers between metal retainers. The outer layer removes aerosols while the inner layer traps solid particles – this protects and extends the life of the outer layer. 7CVP elements are used in bulk liquid coalescing applications or when relatively high efficiency and low pressure drop are required. A distinctive 7DVP media is constructed the same way, but it allows for higher temperature applications. Finite’s ME media type are mist eliminator elements that are constructed comparably to the 7CVP, but offer even higher filtration efficiency for more critical compressed air quality demands. |
Media type 100WS | Water Separator Element (removal of bulk liquids) |
 | This rolled stainless steel mesh element has Inner and Outer Diameter metal retainers with rolled stainless steel mesh between them. It is an extremely sturdy design. With a nominal rating of 100 micron, this media is used for the elimination and reduction of excess liquids in gas streams. It is also a good choice as a prefilter for coalescing grades 6 and 10 where extreme volumes of liquid contaminants are present. |
Media type 3P | Interceptor Element (removal of solids) |
 | Finite’s 3P pleated cellulose element removes solid contaminants, with a 3 micron absolute rating. Because this element is designed to flow from its outside to the inside, it has a strong inner retainer that gives it added strength. 3P particulate “Interceptor” elements are used where relatively fine pore structure is required but very high dirt loading is expected. It may also be used as a prefilter to a coalescing filter in systems where high solid contamination exists. |
Media type A | Adsorption Element (removal of odor) |
 | This hydrocarbon vapor removal element contains an ultra-fine grained, highly concentrated, activated carbon sheet media. These elements are designed to flow from the outside to their inside, therefore they have a strong inner retainer giving them added strength. This media type of element is used to remove hydrocarbon vapor and is often used to remove the smell or taste of compressor lube oil from breathing air. |
Grade 4 | Grade 6 (Standard) | Grade 8 | Grade 10 |
| Parker Finite’s media grade 4 is usually chosen when an extremely high coalescing efficiency is required. Its 99.995% rating is the best available and is ideal for use as a final filter in applications with elevated operating pressures (up to 500 PSIG), or when removing liquid contaminants from gases that are lighter than compressed air. | Grade 6 filters are recomended when a “total removal of liquid aerosols and suspended fines” is required. Because of its overall performance characteristics, grade 6 is most often recommended in industrial applications. This grade is an excellent choice as a prefilter for regenerative desiccant air dryers, as it stops oil or varnish from coating the desiccant. | Grade 8 filters combine high flow rate with high efficiency (98.5%) and long element life. A separate prefilter is not necessary for “normal to light” particulate loading. A grade 8 element is often recommended as protection for refrigerated air dryers. This element allows the dryer to maintain efficiency by preventing the coating of copper coils with the buildup of varnish or oil. | Grade 10 filters are used as prefilters for grades 6 or 8 to remove large amounts of liquid or tenacious aerosols. Grade 10 is referred to as a coarse coalescer, or precoalescer. A grade 10 filter in a media type D filter element is recommended as an after filter for heat regenerated desiccant type air dryers as its one micron rating is perfect for collecting air dryer desiccant fines before they pass downstream. |
