Air cleaning system product lineup
Compressed air is produced by the compressor which sucks, compresses, and concentrates suspended substances in the air. Compressed air is added with impurities generated in the line, resulting in further contamination.
A wide variety of systems compatible with air purity satisfying the customers’ needs are available. It's our pleasure to help you with your order.
What is a KONAN air cleaning system?We developed the system to efficiently remove contaminated substances in the compressed air according to usage in combination with 5 types of air filters that satisfy the quality standard of compressed air based on ISO8573.1. We offer this cleaning system to help customers improve the quality control in various types of production processes.

(Note) In compressed air after condensed oil was removed up to 0.001PPM w/w by UN series, vapor oil at approx. 0.05 to 2PPM is included though it varies depending on the oil type, air temperature and pressure.
Low pressure loss : Employment of mixed-fiber-made coalescing filter media with a very large surface area achieves the high capturing ratio and low decrease in pressure.Increased corrosion resistance : Use of stainless-steel-made punching metal and screen increases corrosion resistance to oil and acid.Silicon free : Non-use of silicon prevents troubles such as welding failure and coating material adhesion failure on the filter downstream side.66ºC heat-resistant temperature : Optimal as a drain separator of after-cooler.Plug-in type : Plug-in element enables easy replacement and minimizes a lower space for replacement.Unified processing ability : Even when series is changed, if the housing type is the same, the treated air volume is the same. Filter selection, mounting and piping are easy as a system.Lineup : Elements selectable from 5 types achieve appropriate system combination suitable for applications.
Two-stage type element which maintains the condensate water separation efficiency of 99% even under the maximum drain loading conditions of 25,000PPM w/w is mounted.●First stagetwo stainless steel orifice tubes provide 10 micron mechanical separation●Second stagein-depth fiber media captures solid and liquid particles to 3 microns
Two-stage type element which removes oil content up to 1PPM w/w even under the maximum drain loading conditions of 2,000PPM w/w is mounted.Suitable for protection of AN/UN series●First stagecaptures larger particles with alternate layers of fiber media and media screen●Second stagecoalesces aerosols and captures solid and multiple layers of epoxy bonded, blended fiber media
Two-stage type element which removes condensed oil content up to 0.01PPM w/w even under the maximum drain loading conditions of 1,000PPM w/w is mounted to remove mist oil content.●First stagemultiple layers of fiber media and media screen remove larger particles, prefiltering the air for the second stage●Second stagemultiple layers of bonded, blended fiber media for fine coalescence-Outer coated, closed cell foam sleeve
Two-stage type element which removes oil and hydrocarbon vapor up to 0.003PPM w/w by activated carbon from compressed air which does not include liquid or mist-like drain is mounted to remove vapor-like oil content.●First stagea stabilized bed finely divided carbon particles removes the majority of the oil vapor●Second stagemultiple layers of fiber media with bonded microfine carbon particles removes the majority of the oil vapor---Multiple layers of fine media prevent particle migration---Outer coated, closed cell foam sleeve prevent fiber migration---Designed for 1000 hour life at rated conditions
Two-stage type element which removes condensed oil content up to 0.001PPM w/w even under the maximum drain loading conditions of 100PPM w/w is mounted to remove mist oil content.●First stagecoated, closed cell foam sleeve acts as prefilter and flow disperser●Second stageimultiple layers of matrix blended fiber media for ultra-fine coalescence-Outer coated, closed cell foam sleeve
All filters are delivered with the maintenance stickers attached. Replace elements at least once a year. (However, replacement interval varies depending on quality of air.)The service life of activated carbon of HN series is determined by time and an amount of vapor oil which inflows (depending on temperature, kind of oil, etc.). The reference service life is 1,000 hours on the rated conditions. Replace elements every 1,000 hours or replace them earlier if odor of oil is detected.

(Note 1) In case of NI-CN8 to NI-CN23, 0.14 to 1.37MPa. In the case where auto drain is not equipped, 0 to 2.06MPa.(Note 2) In the case where auto drain is not equipped, 0 to 0.98MPa. 0 to 1.55MPa as an option.(Note 3) 0 to 1.55MPa as an option(Note 4) Increase the replacement frequency when the quality of air is not good.(Note 5) Cannot be judged by a differential pressure because the service life is determined by time and an amount of vapor oil which inflows. Replace elements every 1,000 hours or replace them earlier if odor of oil is detected.
(Note 1) In the feed-oil type air compressor, aerosol-like oil particle and vapor-like oil particle are mixed with compressed air and discharged together.Aerosol-like oil particle can be removed up to 0.001PPM w/w by UN series, however, vapor-like oil particle is formed by gas molecule, which cannot be mechanically removed.In HN series, vapor-like oil particle and odor of hydrocarbon are removed by activated carbon (0.003PPM w/w)
Do not select filters based on the pipe size but select them with a sufficient margin in consideration of treated air amount and usable pressure.For the maximum treated air amount except for rated pressure conditions of 0.69MPa, multiply the treated air amount on P.3 “Standard specifications” by the correction coefficient equivalent to the minimum usable pressure at the filter inlet.
