Water jeopardizes everything you want yourcompressed air system to do. It ruins product andfouls processes. Here’s how:

• In addition to water, compressed air can also contain dirt, wear particles,bacteria and lubricating fluid.

• Sludge blocks valves and orifices, causing high maintenance and costly air leaks.

How much water is too much?Any amount of water is too much.

• Relative humidity is the amount of water vapor in air relative to what it could

hold at a given temperature.

• Moisture in compressed air remains in a vapor state through the compression

cycle, so it is not a problem until it leaves the compressor.

• Air discharged from a compressor is approximately 150°F to 450°F.

• At 75°F and 75% relative humidity, a 75 HP compressor takes in 46 gallons of

water vapor in 24 hours. When this air is cooled to approximately 35°F at 100

psig, the water vapor condenses into 46 gallons of liquid!

The importance of clean, drycompressed Air

Water mixes with thesepollutants to form an

unwanted abrasive sludge.

This sludge, often acidic,rapidly wears tools andpneumatic equipment.

Sludge corrodes pipingand can foul product and

air-operated devices.

Sullair SD and SM Series Dryers provide clean, dry airby removing the water. The result: corrosion anddamage are eliminated.

• Productivity improves and maintenance costs are reduced.

• The service life of air tools, motors and cylinders is extended.

• The life of your entire compressed air system is prolonged.

The benefits of Sullair SD and SM SeriesRegenerative Dryers:

Clean, dry compressed airSullair SD dryers use desiccant material to adsorb water vapor from compressedair. By combining the proven benefits of desiccant drying with the most advanceddesigns, Sullair offers an extremely compact, reliable system to clean and dry com-pressed air for the most critical applications.

These regenerative dryers are ideal for processes that require an extremely lowdew point to -40°F (-40°C) as standard and optional -100°F (-77°C).

Reliable operation.Simple circuit design, minimal moving parts plus quality manufacturing and

materials assure long, trouble-free service life.

The SM dryers are designed fordew points of -40°F standard andoptional -100°F.

Modular design flexibility.In the SM dryers, Sullair presents anew concept in technology. Sullair’smodular dryer design offers totalinstallation flexibility to meet yourspecific needs. The design utilizesaluminum extrusions that are fullycorrosion-protected, inside and out,resulting in a dryer that canwithstand rigorous environments.

The SM dryers are available from 3to 1650 scfm (.1 to 46.8 m3/min).

Easy expansion.The modular construction allowsyou to expand your dryer packageby adding individual units to meetincreased compressed air needs in the future.

Multiple banking.With multiple banking, you can isolate individual units forservice and maintenance, whilemaintaining a continuous supply ofdry, clean compressed air.

Less than half the size.Sullair’s SM dryer design iscompact and lightweight, and is lessthan half the size of traditionaltwin-tower dryers.

…an air quality guarantee that’s as good as gold.

Sullair assures that its System—compressor, dryer and filter—will meetspecific performance levels throughout its operational life. We offer aone-year test/review period, backed by a purchase refund guarantee, toverify the performance of the Sullair System.

The Sullair System. The Sullair System matches a Sullair compressor, aSullair dryer and Sullair filters. Dry air is filtered to remove atmosphericparticulate, aerosols and other pollutants to provide compressed air for generalpurposes to the most critical application.

Two levels of air quality. Sullair recognizes that the requirements forair quality vary according to each compressed air application. For thisreason, we provide Systems that achieve two distinct levels of air quality.

Level 1 consists of a Sullair compressor and Sullair MPF and MPH orPF/PH filters. The compressed air from this system contains particulates nolarger than .01 micron, including coalesced liquid water and lubricants.Maximum remaining oil aerosol content is 0.01 parts per million byweight (ppm/w) @ 70°F, including oil vapor. The air from this SullairSystem meets the most stringent ISO standard(ISO 8573.1, Class 1) for air quality.

Level 2 offers the highest qualitycompressed air for critical applications. The

air from this Sullair System exceeds the ISO standard(ISO 8573.1, Class 1) for air quality with the use of the MPC or PC filter. TheSystem includes a Sullair compressor and Sullair MPF, MPH and MPC or PF, PHand PC filters. The odor-free compressed air from this system containsparticulates no larger than 0.01 micron, including water and oil aerosol content of0.01 ppm/w @ 70°F. The remaining oil vapor content is less than 0.003 ppm/w.

Select the System. Select the air quality level to meet your plant air orprocess requirements. You can be assured that the quality of air from the SullairSystem you specify will remain consistent for the life of the equipment. Sullairguarantees it. And that’s as good as gold.

Sullair air quality guarantee

These Systems are not intended to remove carbon monoxide, methyl isocyanate or other noxious, corrosive or toxic gases, vapors or fumes. The system does not provide breathing air.
