Air compressors play an important role in an industrial environment, providing the compressed air to the pneumatic controls, valves, process applications and various instruments throughout the plant. In industrial environments, it is critical that gaseous contaminants and particulate matter be removed from the intake air stream of all air compressors. Unfortunately, standard particulate filters offer insufficient protection.  

The CIF is a non-powered unit designed to remove gaseous contaminants that attack intercoolers and other parts of centrifugal compressors, as well as downstream instrumentation. The CIF contains an optional rain louver, pre-filter, two or three banks of modules and a high efficiency final filter. The CIF connects to the compressor with the outlet plenum. Galvanized metal is the standard material used for the construction of the unit housing. Construction is also available in cold rolled steel, aluminum and stainless steel.

THE CIF SYSTEM

THE AIR PURIFICATION PROCESS
  • Air moves through the CIF system in several sections, each treating the air and removing various airborne contaminants. 
  • Purafil media within the CIF reacts with and neutralizes corrosive contaminants in the intake air, preventing corrosion within the compressor.
If the ambient intake air contains corrosive gases such as Sulfur Dioxide (SO2), Oxides of Nitrogen (NOx), and Hydrogen Sulfide (H2S), it will raise the acidity level of the compressed air creating a corrosive condensate which attacks metal surfaces.

Critical copper, aluminum and cast steel compressor parts (photo) are the most susceptible to these corrosive gases. An air compressor intercooler can be severely damaged if it comes in contact with this corrosive condensate. Other key components of the compressor - impellers, diffusers and the compressor casings - can also be damaged.
SECTION 1
The first section of the process is a particulate prefilter designed to remove dust and dirt. This prefilter removes particulates 10 microns in diameter or greater. The primary purpose of the prefilter is to protect the chemical filters and the high efficiency final filter. The prefilter retains its structural integrity in moist environments and it, therefore, also serves as a low efficiency mist eliminator.
SECTION 2
The second section is the chemical filtration section where Purafil chemical media is used to remove gaseous contaminants from the air stream. Multiple stages of media may be required.
SECTION 3
The last section is the final particulate filter. This filter is a high efficiency filter which removes particulates equal to or greater than 1-2 microns.


Purafil, Inc., the industry leader in gas-phase filtration, developed the Compressor Intake Filter (CIF) system to remove corrosive gases such as Sulfur Dioxide (SO2), and Hydrogen Sulfide (H2S). These gases increase acidity levels which lead to decreased compressor efficiency. Interestingly, concentration levels of these gases, which are acceptable for humans, are dangerously high for air compressors. The service life of a compressor is extended and costly repairs are avoided when corrosive gases are removed from the intake air stream.

The CIF is a multi-stage, highly efficient air purification system that removes gases and particulates, and prevents corrosion caused by airborne contaminants. In the absence of CIF protection, these contaminants can result in reduced efficiency, costly repairs, and equipment downtime.

Industry leaders recognize Purafil's expertise in this field and rely upon Purafil to protect their expensive air compressors from corrosive gases commonly found in industrial environments.

Purafil's CIF is compatible with most major air compressor manufacturers, including Ingersoll-Rand, Elliott, Demag, IHI, Joy Cooper, and Atlas Copco to name a few.
