Full Product Description
The Tsunami Portable Pure-5T Regenerative Desiccant Air Dryer brings the performance of Tsunami's Pure Series regenerative drying technology into a compact, portable compressed air treatment package.
Rated for up to 15 CFM and designed for approximately 5 HP compressed air systems, PN 21999-1100 combines two-stage pre-filtration, twin regenerative desiccant towers, a 1-gallon storage tank, outlet pressure regulation, and a carrying handle into one portable system.
This makes the Portable Pure-5T an excellent solution when extremely dry compressed air is required at multiple locations, for temporary installations, troubleshooting air quality problems, demonstration applications, automotive refinishing, or other processes where permanently mounting a dryer is not practical.
Before compressed air reaches the regenerative dryer, it passes through Tsunami's integrated two-stage pre-filtration system:
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, 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 dryer automatically switches between towers. This allows the molecular sieve desiccant to continuously regenerate while providing an uninterrupted supply of exceptionally dry compressed air.
The Pure-5 drying system consumes approximately 1 CFM of compressed air during regeneration and can produce dew points down to -80°F and relative humidity levels down to approximately 0.01% RH under proper operating conditions.
The Portable Pure-5T also incorporates a 1-gallon storage tank to help maximize laminar airflow during regeneration cycles. An outlet regulator and high-flow connection provide convenient control and connection to downstream equipment.
Unlike the wall-mounted Pure-5 and Pure-5T models, the 21999-1100 is specifically designed for portability, allowing the complete drying system to be moved between work areas or connected temporarily where clean, dry compressed air is needed.

Benefits
Portable Extremely Dry Compressed Air
The Portable Pure-5T provides the drying performance of a regenerative desiccant dryer in a package that can be moved to the application instead of permanently installed in one location.
This makes it ideal for shops, service technicians, testing, temporary installations, and applications requiring dry air in multiple work areas.
Dew Points Down to -80°F
The Pure Series regenerative drying system can provide dew points down to -80°F, making it suitable for applications requiring considerably drier compressed air than a conventional refrigerated air dryer can typically provide.
Complete Air Treatment Package
The Portable Pure-5T integrates:
Water separation
Oil coalescing filtration
Regenerative desiccant drying
1-gallon storage
Outlet pressure regulation
into one portable compressed air treatment system.
Integrated 1-Gallon Storage Tank
The included 1-gallon tank helps maximize laminar airflow during regeneration cycles as the dryer alternates between its two desiccant towers.
The tank is part of the dryer system and is not intended to replace the compressor's primary receiver tank.
Continuous Twin-Tower Regeneration
One desiccant tower dries the compressed air while the second regenerates. The dryer automatically switches towers approximately every two minutes, allowing the system to continuously regenerate its desiccant while operating.
Protects the Desiccant
Liquid water and compressor oil can quickly contaminate molecular sieve desiccant. Tsunami's integrated water separator and oil coalescing filter remove these contaminants before they reach the regenerative drying towers.
Easy to Move Between Applications
The portable frame and carrying handle allow the complete dryer package to be transported between work areas, equipment, or compressed air sources without requiring a permanent wall-mounted installation.
Useful for Air Quality Troubleshooting
Because the complete filtration and drying system can be connected temporarily, the Portable Pure-5T is especially useful for diagnosing whether moisture or compressed air quality is contributing to paint, coating, pneumatic equipment, or production problems.

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 Portable 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 bulk 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 through conventional compressed air filtration.
The Portable Pure-5T contains two regenerative desiccant towers:
One tower actively removes water vapor from the compressed air.
The second tower uses approximately 1 CFM of dry sweep air to regenerate its desiccant.
Each tower dries for approximately 120 seconds.
Approximately every two minutes, the dryer automatically switches air flow between the two towers.
The regenerated tower begins drying while the previously active tower begins regeneration.
The integrated 1-gallon storage tank helps stabilize airflow through the system during these regeneration cycles.
Why Does the Portable Pure-5T Have a 1-Gallon Tank?
The integrated 1-gallon tank is part of Tsunami's Pure-5T regenerative drying design.
Its purpose is to help maximize laminar airflow during regeneration cycles as the dryer switches between its two desiccant towers.
The 1-gallon tank should not be confused with the primary compressed air receiver used with the compressor. It is a small dedicated tank designed to support dryer performance and smoother air delivery.
Portable Pure-5T vs. Wall-Mounted Pure-5T
The Portable Pure-5T uses the same basic Pure-5 regenerative drying technology but packages the system for mobility.

Important Sizing Information
The Portable Pure-5T has a maximum rated capacity of 15 CFM and is designed for approximately 5 HP compressed air systems.
Tsunami's published flow ratings are 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 performance and affect downstream air quality.
The Pure-5 drying system also consumes approximately 1 CFM of compressed air for regeneration, which should be considered when determining total compressor capacity.
For best performance, the dryer should be selected according to actual CFM demand, operating pressure, inlet air temperature, and available compressor capacity, rather than compressor horsepower alone.
Why Choose the Tsunami Portable Pure-5T?
The Tsunami Portable Pure-5T provides a practical solution for applications that need extremely dry compressed air without permanently installing a regenerative dryer.
Its integrated pre-filtration protects the molecular sieve desiccant, while the twin-tower regenerative design continuously restores the desiccant during operation.
The 1-gallon storage tank, outlet regulator, and carrying handle make the dryer particularly useful for temporary installations, troubleshooting, service work, demonstrations, and shops where dry compressed air is needed at multiple locations.
For applications requiring up to 15 CFM of extremely dry compressed air, PN 21999-1100 provides a complete portable filtration and drying solution in one compact package.
