Full Product Description
The Tsunami Pure-10 Pure Series Regenerative Air Dryer is a compact, wall-mounted compressed air treatment system engineered to provide exceptionally clean, dry compressed air for commercial shops, manufacturing equipment, paint applications, and other moisture-sensitive processes.
Rated for up to 40 CFM and designed for approximately 10 HP compressor systems, the Pure-10 combines Tsunami's integrated two-stage pre-filtration system with twin regenerative desiccant towers to remove liquid water, compressor oil, aerosols, particulates, and water vapor from the compressed air stream.
The Pure-10 can provide dew points down to -80°F and relative humidity levels down to approximately 0.01% RH, making it an excellent choice when compressed air must be significantly drier than the air produced by a conventional refrigerated air dryer.
Before compressed air reaches the regenerative dryer, it passes through two stages of filtration:
-
First Stage Water Separator: Removes liquid water and particulate contamination down to 10 micron.
-
Second Stage Oil Coalescing Filter: Removes bulk oils and aerosols while filtering fine particulate contamination down to 0.01 micron.
After pre-filtration, the compressed air enters the twin regenerative desiccant towers. One tower actively removes water vapor while the second tower regenerates using a small amount of previously dried compressed air.
Approximately every two minutes, the Pure-10 automatically switches between towers. One molecular sieve desiccant bed remains in service while the other regenerates, providing a continuous supply of extremely dry compressed air.
The Pure-10 uses approximately 2.2 CFM of compressed air during regeneration, with each tower operating for approximately 120 seconds before switching.
The Pure-10 is available in four primary voltage and drain combinations:
- PN 21999-1010 – 120V with Float Drains
- PN 21999-1010-220 – 220V with Float Drains
- PN 21999-1010-MM – 120V with Moisture Minder® Pneumatic Drains
- PN 21999-1010-MM-220 – 220V with Moisture Minder® Pneumatic Drains
All four configurations provide the same 40 CFM maximum flow capacity, twin-tower regenerative drying performance, 175 PSI maximum operating pressure, and dew points down to -80°F.

Benefits
Provides Extremely Dry Compressed Air
The Pure-10 can achieve dew points down to -80°F, providing substantially drier compressed air than a conventional refrigerated dryer.
This makes the Pure-10 well suited for applications where moisture can affect equipment performance, product quality, paint finishes, or manufacturing processes.
Complete Filtration and Drying Package
The Pure-10 combines:
- Water separation
- Oil coalescing filtration
- Fine particulate filtration
- Twin-tower regenerative desiccant drying
into one compact wall-mounted air treatment system.
Continuous Regenerative Drying
The twin-tower design allows one tower to actively dry compressed air while the second tower regenerates.
Approximately every two minutes, the system automatically switches towers, allowing the molecular sieve desiccant to continuously restore its moisture-removal capacity.
120V or 220V Electrical Options
The Pure-10 can be ordered for either 120V or 220V electrical power, providing greater installation flexibility than the smaller Pure Series dryers.
Choice of Automatic Drain Systems
The Pure-10 is available with either standard automatic float drains or Tsunami Moisture Minder® pneumatic drains.
This allows the dryer configuration to be matched to the customer's preferred condensate management system.
Protects the Desiccant
Liquid water and compressor oil can quickly contaminate molecular sieve desiccant.
The Pure-10's integrated water separator and oil coalescing filter remove these contaminants before the compressed air enters the regenerative towers, helping maintain drying performance and extend desiccant service life.
Compact Wall-Mounted Design
Despite its 40 CFM capacity, the Pure-10 packages the pre-filters, controls, and twin regenerative towers into a compact wall-mounted design, eliminating the floor space required by many larger industrial desiccant dryers.

Proper pre-filtration is especially important with regenerative desiccant dryers because liquid water, compressor oil, and particulate contamination can contaminate molecular sieve desiccant and reduce dryer performance.
How the Tsunami Pure-10 Works
Compressed air first enters the integrated water separator, where liquid water and larger particulate contamination are removed.
The air then passes through the oil coalescing filter, which removes bulk compressor oil, aerosols, and fine particulate contamination before the compressed air reaches the regenerative dryer.
Inside the dryer, molecular sieve desiccant adsorbs water vapor that cannot be removed by conventional compressed air filtration.
The Pure-10 contains two regenerative desiccant towers:
- One tower actively removes water vapor from the compressed air.
-
The second tower uses approximately 2.2 CFM of dry sweep air to regenerate its desiccant.
-
Each tower dries for approximately 120 seconds.
- Approximately every two minutes, the control system switches air flow between the two towers.
- The regenerated tower begins drying while the previously active tower begins regeneration.
This automatic cycling provides a continuous supply of extremely dry compressed air without requiring manual desiccant regeneration during normal operation.
120V vs. 220V Pure-10
The Pure-10 is available for either 120V or 220V electrical power.
120V Models
-
PN 21999-1010: Float drains
-
PN 21999-1010-MM: Moisture Minder® pneumatic drains
The 120V configuration is convenient for installations where standard 120V electrical service is readily available.
220V Models
-
PN 21999-1010-220: Float drains
-
PN 21999-1010-MM-220: Moisture Minder® pneumatic drains
The 220V configurations provide the same compressed air drying capacity and performance but allow the dryer controls to operate from a 220V electrical supply.
Voltage selection does not change the 40 CFM rated drying capacity.
Float Drain vs. Moisture Minder® Pneumatic Drain
Float Drain Models
PN 21999-1010 – 120V
PN 21999-1010-220 – 220V
These configurations use automatic float-operated drains on the integrated pre-filtration system.
Condensate is automatically discharged as it accumulates within the filter bowls, providing a simple and economical automatic drainage solution.
Moisture Minder® Pneumatic Drain Models
PN 21999-1010-MM – 120V
PN 21999-1010-MM-220 – 220V
These configurations use Tsunami Moisture Minder® pneumatic drains for automatic condensate removal.
The Moisture Minder system provides pneumatic condensate drainage without relying on an electrical timer drain.
Important Sizing Information
The Pure-10 has a maximum rated capacity of 40 CFM and is designed for approximately 10 HP compressed air systems.
Tsunami's published flow rating is based on operating conditions of approximately:
- 100°F inlet air temperature
- 175 PSI inlet pressure
- 100 PSI outlet pressure
- 80 PSI minimum inlet pressure
Lower inlet pressure and higher inlet air temperatures can reduce dryer capacity and downstream air quality.
The Pure-10 also consumes approximately 2.2 CFM of compressed air during regeneration. This air consumption should be considered when calculating the total compressed air capacity required from the compressor.
For best performance, the dryer should ultimately be selected according to:
- Actual system CFM demand
- Operating pressure
- Inlet air temperature
- Available compressor capacity
- Required downstream dew point
Compressor horsepower should be considered a general sizing reference rather than the only sizing factor.
