Full Product Description
The Tsunami Portable Pure-5TMM Regenerative Desiccant Air Dryer combines Tsunami's Pure Series twin-tower drying technology with a portable frame, integrated 1-gallon storage tank, and Moisture Minder® pneumatic condensate drains.
Rated for up to 15 CFM and designed for approximately 5 HP compressed air systems, PN 21999-1100-MM provides a complete portable compressed air treatment package for applications that require exceptionally clean, dry air but do not justify or allow a permanently installed dryer.
The Portable Pure-5TMM is particularly useful for automotive refinishing, professional painting, temporary production equipment, equipment demonstrations, compressed air troubleshooting, mobile service applications, woodworking finishes, and other processes where moisture can compromise equipment performance or product quality.
Before compressed air reaches the regenerative dryer, it passes through Tsunami's integrated two-stage pre-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, compressed air enters the twin regenerative desiccant towers. One tower removes water vapor from the compressed air while the second tower regenerates using a small amount of previously dried sweep air.
Approximately every two minutes, the dryer automatically switches between towers. This allows the molecular sieve desiccant to continuously regenerate while providing a steady supply of exceptionally dry compressed air.
The Pure-5 regenerative drying system consumes approximately 1 CFM of compressed air during regeneration and can provide dew points down to -80°F and relative humidity levels down to approximately 0.01% RH under proper operating conditions.
The Portable Pure-5TMM also incorporates a 1-gallon storage tank designed to help maximize laminar airflow during regeneration cycles. An outlet regulator provides control of downstream pressure, while the integrated carrying handle allows the complete system to be transported between applications.
What separates PN 21999-1100-MM from the standard Portable Pure-5T is its Moisture Minder® pneumatic drain system. These drains use an intermittent pneumatic pilot signal to automatically discharge collected condensate without requiring electrical power at the drain valves.
Key Features
15 CFM maximum air flow
Designed for approximately 5 HP compressed air systems
Portable regenerative desiccant dryer
Moisture Minder® pneumatic drains
Pneumatic drains require no electrical power at the drain valve
Designed for automatic condensate removal with minimal compressed air loss
The Portable Pure-5TMM provides regenerative desiccant drying performance in a package that can be moved between compressed air systems, work areas, or pieces of equipment.
Instead of permanently installing a dryer in one location, the complete air treatment package can travel wherever extremely dry compressed air is required.
Dew Points Down to -80°F
Tsunami's Pure Series regenerative drying technology can provide dew points down to -80°F under proper operating conditions.
This makes the Portable Pure-5TMM suitable for applications requiring considerably drier air than a conventional refrigerated compressed air dryer can typically provide.
Moisture Minder® Pneumatic Drains
The 21999-1100-MM is equipped with Tsunami Moisture Minder® pneumatic drains rather than standard float drains.
The pneumatic drains use a pilot air signal to automatically discharge collected condensate. They do not require electrical power at the drain valve and are designed to minimize compressed air loss during drainage.

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 drying performance.
How the Tsunami Portable Pure-5TMM 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.
The Moisture Minder® pneumatic drains automatically remove collected condensate from the pre-filtration system using a pneumatic pilot signal.
Once filtered, compressed air enters the regenerative desiccant dryer.
The Portable Pure-5TMM contains two molecular sieve 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 between towers.
The regenerated tower begins drying while the previously active tower begins regeneration.
The integrated 1-gallon tank helps smooth airflow through the system during these regeneration cycles.
How the Moisture Minder® Pneumatic Drains Work
The 21999-1100-MM replaces conventional float drains with Tsunami Moisture Minder® pneumatic drain valves.
The drain uses an intermittent pneumatic pilot signal to control condensate discharge.
During operation:
Condensate collects within the drain.
A pneumatic pilot signal actuates the internal piston.
Condensate is moved into the pressurized discharge reservoir.
When the pilot signal is relieved, the drain port opens.
The stored condensate is automatically discharged.
The design requires no electrical power at the drain valve and minimizes the loss of compressed air during condensate removal.
Why Choose Pneumatic Drains?
Condensate drainage is critical to maintaining compressed air filtration performance.
If water and contamination are allowed to accumulate in the pre-filters, filtration efficiency can decrease and downstream equipment may be exposed to moisture and contamination.
Tsunami's Moisture Minder® pneumatic drain system provides several advantages:
Automatic condensate removal
No electrical power required at the drain valve
Minimal compressed air loss
Simple pneumatic operation
Reliable condensate management
Helps protect downstream filters and dryer components
For applications where dependable automatic drainage is a priority, the 21999-1100-MM provides an upgrade over the standard float-drain Portable Pure-5T.
Why Does the Portable Pure-5TMM Have a 1-Gallon Tank?
The integrated 1-gallon storage tank is part of Tsunami's Pure-5T regenerative dryer design.
The tank is designed to help maximize laminar airflow during regeneration cycles as the dryer switches between its two desiccant towers.
This small receiver is dedicated to dryer operation and should not be considered a replacement for the compressor's main air receiver.
Portable Pure-5T vs. Portable Pure-5TMM
Both portable models provide the same 15 CFM regenerative drying capacity, 1-gallon storage tank, 120V operation, and portable configuration.
The primary difference is the condensate drain system.

Important Sizing Information
The Portable Pure-5TMM is rated for a maximum airflow of 15 CFM and is intended for approximately 5 HP compressed air systems.
Tsunami's published Pure Series 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 temperatures can reduce dryer performance and downstream air quality.
The Pure-5 drying system also consumes approximately 1 CFM of compressed air during regeneration, which should be considered when determining available compressor capacity.
For best dryer performance, sizing should be based on:
Actual compressed air demand in CFM
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.
Why Choose the Tsunami Portable Pure-5TMM?
