Tsunami Pure-7 Series

25 CFM Compressed Air Dryer

Regenerative Desiccant

The Pure-7 Series Regenerative Dryer is rated for 25 CFM airflow, and fitted for 7 Hp compressors. The Pure-7 system uses a Solenoid Timer Valve to control the dryer and Tsunami pre-filtration to assure removal of water, oil, and particulates before entering the dryer.

Tsunami Pre Filtration

Tsunami pre-filtration includes the water separator and oil coalescing filter to remove liquid water, bulk oils and particulate.

Regenerative Towers

Tsunami’s Regenerative Drying Technology uses sweep air to regenerate the towers during operation. It's like changing the desiccant every two minutes.

Efficient Construction

Tsunami Dryers are efficiently designed and constructed with very few moving parts, reducing potential stress points.
