Full Product Description
The Tsunami Pure-5T Pure Series Regenerative Air Dryer combines Tsunami's compact twin-tower regenerative drying technology with an integrated 1-gallon storage tank for applications requiring exceptionally clean, dry compressed air.
Rated for up to 15 CFM and designed for approximately 5 HP compressor systems , the Pure-5T is ideal for automotive finishing, professional paint applications, woodworking, pneumatic equipment, small manufacturing systems, and other applications where moisture can negatively affect equipment or finished products.
Unlike the standard wall-mounted Pure-5, the Pure-5T incorporates a 1-gallon storage tank attachment . Tsunami designed this small receiver to help maximize laminar airflow during the regeneration cycle, creating a smoother air supply as the dryer alternates between its two desiccant towers.
Before compressed air reaches the regenerative dryer, it passes through an integrated two-stage pre-filtration system:
- First Stage Water Separator: Removes liquid water and particulates down to 10 micron.
- Second Stage Oil Coalescing Filter: Removes bulk oils and aerosols while filtering particulates down to 0.01 micron.
After pre-filtration, compressed air enters the twin regenerative desiccant towers. One tower actively dries the compressed air while the second tower regenerates using a small amount of previously dried sweep air.
Approximately every two minutes, the dryer switches between towers. This allows the molecular sieve desiccant to continuously regenerate while providing a steady supply of dry compressed air.
The Pure-5T consumes approximately 1 CFM of compressed air during regeneration and can achieve dew points down to -80°F and relative humidity levels down to approximately 0.01% RH under proper operating conditions.
Two drain configurations are available:
- PN 21999-1105-T – Float Drains: Standard automatic float drain configuration.
- PN 21999-1105-T-MM – Moisture Minder® Pneumatic Drains: Pneumatically operated automatic condensate drains.
Both configurations include the 1-gallon storage tank and outlet regulator and provide the same 15 CFM regenerative drying capability.

Benefits
Extremely Dry Compressed Air
The Pure-5T can provide dew points down to -80°F , making it ideal for applications requiring significantly drier compressed air than a conventional refrigerated air dryer can typically provide.
Integrated 1-Gallon Storage Tank
The Pure-5T differs from the standard wall-mounted Pure-5 by incorporating a 1-gallon receiver tank . The tank helps support smooth, laminar airflow as the regenerative dryer switches between towers.
Complete Filtration and Drying System
The Pure-5T includes two stages of pre-filtration, regenerative drying, a storage tank, and an outlet regulator in one compact system.
Continuous Twin-Tower Regeneration
One tower removes water vapor from the compressed air while the second tower regenerates. Approximately every two minutes, the towers alternate automatically.
Automatic Desiccant Regeneration
The dryer uses approximately 1 CFM of dry sweep air to regenerate the inactive desiccant tower during operation, eliminating the need to manually regenerate the desiccant between operating cycles.
Protects the Desiccant
The integrated water separator and oil coalescing filter remove liquid water, compressor oil, aerosols, and particulate contamination before these contaminants can reach the molecular sieve desiccant.
Choice of Drain Systems
Choose PN 21999-1105-T with standard float drains or PN 21999-1105-T-MM with Moisture Minder® pneumatic drains depending on your preferred condensate management system.
Compact Wall-Mounted Package
Despite incorporating filtration, twin desiccant towers, and a 1-gallon receiver, the Pure-5T maintains a compact footprint suitable for wall mounting near the compressor or point of use.

Integrated Two-Stage Pre-Filtration
Every Pure-5T includes Tsunami two-stage pre-filtration before the regenerative dryer.
Stage 1 – Water Separator
- Removes liquid water
- Filters particulate down to 10 micron
- Automatic condensate drain
- Water Separator: PN 21999-0390
- Replacement Element: PN 21999-0846
Stage 2 – Oil Coalescing Filter
- Removes bulk oils and aerosols
- Filters fine particulate down to 0.01 micron
- Automatic condensate drain
- Oil Coalescing Filter: PN 21999-0390-Z-FD
- Replacement Element: PN 21999-0394
Proper pre-filtration is particularly important for regenerative desiccant dryers because liquid water and compressor oil can contaminate molecular sieve desiccant and reduce dryer performance and service life.
How the Tsunami Pure-5T 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 oil aerosols and fine particulate contamination.
Once properly filtered, the compressed air enters the regenerative dryer.
The Pure-5T contains two molecular sieve desiccant towers :
- One tower actively removes water vapor from the compressed air.
- The second tower regenerates using approximately 1 CFM of dry sweep air.
- Each tower operates for approximately 120 seconds.
- The dryer automatically switches towers approximately every two minutes.
- The previously regenerated tower begins drying while the saturated tower begins regeneration.
The integrated 1-gallon storage tank helps smooth airflow through the system during these regeneration cycles, helping maximize laminar airflow as the dryer alternates between towers.
Why Does the Pure-5T Have a 1-Gallon Tank?
The 1-gallon tank is not intended to function as the primary compressed air receiver for a 5 HP compressor.
Instead, Tsunami incorporates the tank into the Pure-5T to help maximize laminar airflow during the regenerative drying cycle .
As the dryer switches between desiccant towers, airflow conditions can change momentarily. The small receiver helps provide additional air volume and smooth airflow through the drying system.
For applications that experience fluctuating or intermittent air demand, this configuration can provide advantages over the standard Pure-5 wall-mounted dryer.
Float Drain vs. Moisture Minder® Pneumatic Drain
PN 21999-1105-T – Float Drain
The standard Pure-5T uses automatic float-operated drains on the pre-filtration system.
Condensate is discharged automatically as it accumulates in the filter bowls, providing a straightforward automatic drainage solution.
PN 21999-1105-T-MM – Moisture Minder® Pneumatic Drain
The 21999-1105-T-MM uses Tsunami Moisture Minder® pneumatic drains for automatic condensate removal.
The pneumatic system provides dependable automatic drainage without relying on an electrical timer drain.
Important Sizing Information
The current Tsunami Pure-5T is rated for a maximum airflow of 15 CFM and is designed for approximately 5 HP compressor systems .
Tsunami's published dryer flow rating is based on 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 affect dryer performance and downstream air quality.
The dryer also consumes approximately 1 CFM of compressed air during regeneration , which should be considered when calculating available compressed air capacity.
The Pure-5T should ultimately be selected according to actual system CFM, operating pressure, inlet temperature, and available compressor capacity , rather than compressor horsepower alone.
Why Choose the Tsunami Pure-5T?
The Tsunami Pure-5T combines the compact design and regenerative drying performance of the Pure-5 with an integrated 1-gallon storage tank and outlet regulator .
This configuration is particularly useful for applications where smooth air delivery during tower regeneration is important.
The Pure-5T packages:
- Two-stage compressed air pre-filtration
- Twin regenerative desiccant towers
- Automatic desiccant regeneration
- 1-gallon storage tank
- Outlet pressure regulator
- Automatic condensate drainage
into one compact wall-mounted compressed air treatment system.
For users who prefer pneumatic condensate management, the 21999-1105-T-MM Moisture Minder® version provides pneumatic drains while maintaining the same drying capacity and 1-gallon tank configuration.
