The Spirovent® Air Eliminator / Dirt Separator employs a patented Spirotube® coalescing / barrier medium that "scrubs" the air from the system fluid and gives the dirt something to collide into. Simple to install with a straight in-line design it is available in the "Dirt" model as a sealed vessel and the "Drain" model that includes a removable head and tube sheet construction. This allows access to the Spirotube bundle for inspection or cleaning.

All units are fabricated steel and available from 2" through 36" pipe size and can handle flows to over 30,000 GPM. Custom fabrication is available for special project requirements. For large high velocity systems the "HV" Series is available specifically for central plants and district systems where large volumes of water are being distributed.

The air/water/dirt mixture enters the Spirovent and the Spirotube coalescing / barrier medium combined with a drop in velocity allows the air and dirt to break free of the flow path. All free and entrained air is removed through the integral vent mechanism along with up to 99.6% of the dissolved air. The dirt falls to the collection chamber in the bottom where it can be purged through the standard ball valve. Dirt and sediment with a specific gravity greater than water and to below 30 microns are separated in a continuous circulating system.
