COMPRESSED AIR FILTERS COMPRESSED AIR DRYERS SUB-MICRON FILTERS FILTER-DRYER COMBINATIONS Compressed Air Filters Ultra clean compressed air for packaging, fluidics, laboratory, and instrumentation. CATALOG 6000-KF17 AIR-GUARD Filter AIR-GUARD Filter Compressor, aftercooler, receiver tank Compressed Air Filtration End-Use Filters Filtering the entire compressed air system at one central location does not generally provide sufficient cleaning for all end-use applications. Moreover, most compressed air piping contains some amount of rust, scale, and condensed liquids. Water vapor that may be present in warm air will tend to condense into liquid when the air cools. A compressed air filter installed just upstream of the end-use is generally the most efficient means of ensuring clean, dry air. These end-use filters can provide clean air to meet individual process requirements. A coalescing filter should be specified due to its long service life where liquid contaminants may be encountered. You should not undersize a compressed air filter. Exceeding the listed flow rate of the filter will have a proportionate decrease in the service life of the cartridge elements. Frequent cartridge replacement necessitated by under sizing an application significantly increases maintenance costs. Maximum efficiency is generally obtained between 15%–100% of the maximum rating. Vapor and Condensation Many types of pneumatic equipment and processes use compressed air that must be clean, dry, and oilfree. This requires the removal of liquids, aerosols, dust, and solid particulates from the airstream. Generally, only condensed liquids need to be removed. Visible fog or mist is actually composed of condensed liquid droplets. These are easily removed by using a coalescing 2 compressed air filter at the end-use point. Vapor is liquid in evaporated form. In this gaseous state, the liquid vapor will be invisible. Oil and water vapor are commonly present in compressed air systems. If either type of vapor must be removed, a compressed air dryer must be used. Desiccant dryers, for instance, use media that attracts the vapor molecules through a process called “adsorption”. KING Ultra-C Filters The preferred choice for high efficiency compressed air filtration, KING Ultra-C Filters utilize a two stage design with a color indicating cartridge. These filters deliver extremely clean air for fluidic systems, critical instrumentation, packaging, paint, and coatings systems. The primary first stage element effectively removes not only solid particulate but also the extremely small aerosols of water and oil present in compressed air systems. A second “polisher” cartridge element guards against any carryover of contaminants and helps deliver even cleaner air output from the filter. KING Ultra-C filters are available in three configurations to suit the specific application. All are based on the high efficiency coalescing action Ultra-C cartridge elements which remove oil, water, and particulate from the air stream. A compact single stage model doesn’t skimp on performance while offering a small footprint. The standard two stage color-change model incorporates a color change feature to signal the need for cartridge www.kingfilters.com ULTRA-C Color Change Filter VISI-GUARD Filter-Dryer ULTRA-C Color Change Filter METL-GUARD Desiccant Dryer (Oil Vapor) replacement. A combination filter-regulator-gauge com prises the Ultra-C Air Control Station. Each is offered with an automatic drain sump to reduce maintenance and assure continuous dry compressed air. KING Air Guard Filters Larger capacity flow rates and more durable construction mark our KING Air Guard line of compressed air filters. As with all KING filters, they deliver extremely clean air for fluidic systems, critical instrumentation, packaging, paint, and coatings systems. Models rated for 60 scfm and up incorporate right angle inlet/outlet porting for optimal air line piping arrangement.

This allows for filter cartridge replacement without service interruption. Shut off valves quickly permit temporary re-routing of the air flow. For extremely critical air quality applications, another filter should be present in the bypass as well. Air Flo w Shut Off Valve Main Air Supply Intake Air Temperature End Use Reduce energy consumption by supplying compressors with outside air ducted directly to the intake. Cooler air is denser and will require less energy to compress. Simply introducing outside air into the space where the compressor resides will not realize these savings because of the ambient heat it will absorb. Distribution Piping System Pressure Insufficient air flow or pressure is often caused by the compressed air system piping. Incorrect pipe size may cause pressure drops. Try to reduce the number of sharp right angle bends in piping and ensure adequate size of the main piping run in the facility. When pressure is set relatively high in the attempt to deliver adequate air flow to the end use points, compressors increase their energy demand and air consumption may needlessly rise at discharge points. Vertical Take-Off (180 Bend) Main Air Supply KING Filters Pressure Regulator with Gauge 60 80 Air distribution piping should be large enough in diameter to minimize pressure drop. A loop system is generally recommended, with all piping sloped away from the compressor to accessible drop legs and drain points. Piping from the header to points-of-use should connect to the top or side of the header to avoid being filled with condensate.

Recommended options are listed below. Our Ultra-C and Type 750/800 cartridges meet the particulate require ments of ISO 8573-1* Quality Class 1 speci fication for compressed air. Type 300/300 cartridge sets provide lower pressure drop in applications and meet ISO 8573-1 Quality Class 3 specification for particulate removal. KING filter cartridge elements provide equal efficiency regardless of flow rate. Filtering efficiency does not diminish during the life of the cartridges so you can be assured of consistent performance and air quality. Without question, most compressed air systems contain solid and liquid contaminants that affect performance and increase wear on equipment. Precision pneumatic instrumentation including KING-GAGE tank level gauging systems require clean, dry, and oil-free compressed air for trouble free operation. * ISO 8573-1:2010 specifies purity classes of compressed air with respect to particles, water and oil independent of the location in the compressed air system at which the air is specified or measured. ISO Class noted is for particulate removal only. 20 scfm cartridge sets 0.1 micron 99.998% U3002, U3003 0.1 micron 99.998% A22-11-6-5 cartridge set 2.0 micron 98.0% A22-11-1-1 cartridge set Ultra-C scrubber Ultra-C polisher Type 750 scrubber Type 800 polisher Type 300 scrubber Type 300 polisher 60 scfm cartridge sets 0.1 micron 99.998% 22-31-6-5 cartridge set 2.0 micron 98.0% 22-31-1-1 cartridge set Type 750 scrubber Type 800 polisher Type 300 scrubber Type 300 polisher Type 750 scrubber Type 800 polisher Type 300 scrubber Type 300 polisher Type 750 scrubber Type 800 polisher Type 300 scrubber Type 300 polisher Type 750 scrubber See desiccant selections below: 80 scfm cartridge sets 0.1 micron 99.998% 22-41-6-5 cartridge set 2.0 micron 98.0% 22-41-1-1 cartridge set 100 scfm cartridge sets 0.1 micron 99.998% A22-51-6-5 cartridge set 2.0 micron 98.0% A22-51-1-1 cartridge set 12 scfm cartridge & desiccant 0.1 micron 99.9% 9318-80 1730 SG-1 desiccant Water vapor (-50° F / - 45° C dew point) Service Temp. 100° F / 38° C 1730-5 MS-1 desiccant Water vapor (-100° F / -73° C dew point) Service Temp. 200° F / 93° C 1730-4 AC-1 desiccant Oil vapor (≤ 0.5 ppm w/w) Service Temp. 120° F / 49° C 11 Industries Served Founded in 1937, King Engineering supplies the food, dairy, beverage, personal care, pharmaceutical, industrial, and chemical sectors as well as specialized applications for the marine industry.
