Superior dry air quality achieves very low dew points (as low as –80 °f) and relative humidity down to 0.01% rh — ideal for critical applications where moisture damages tools or processes. Pre-filtration ensures that oil and particulates are removed before drying, maximizing desiccant life. Pre-filtration overview: tsunami filters are machined from the highest quality materials and are anodized inside and out to ensure ultimate durability against corrosion and trapped contaminates. Water separator removes water and filters particulate down to 10 micron. The oil coalescing filter removes oil aerosols down to .001 ppm and particulates down to .01 micron. Tsunami pure series two-tower contains two parallel desiccant towers filled with high-performance molecular sieve desiccant. Only one tower is actively drying at any given time. While one tower dries air, the other tower regenerates, allowing for continuous drying. Drying phase: moist compressed air enters the active tower. Moisture molecules stick to the molecular sieve surface (adsorption). The outgoing air is extremely dry with a very low dew point suitable for sensitive applications. Regeneration phase: after a set interval (usually ~2–3 minutes), flow shifts to the other tower. The off-line tower is regenerated using a small portion of the already dried air (sweep air). This removes the moisture previously captured by the desiccant, restoring its drying capacity. Simple regenerative design with few moving parts reduces stress points and maintenance. Cycling design continuously refreshes desiccant, minimizing downtime. How the automatic float drain works: Condensate fills a chamber containing a mechanical float. As the float rises, it mechanically opens a drain orifice. Once the liquid level drops, the float falls and closes the valve.
