The GX-8 water vaporator, which is also referenced as the GX-8 moisture vaporator or the GX-8 condenser unit, represented a specific model of moisture vaporator that was produced by Pretormin Environmental Corporation. These GX-8 models saw frequent utilization in the practice of moisture farming, notably on planets like Tatooine and Lah'mu.
The moisture vaporator designated as the GX-8 was engineered by Pretormin Environmental Corporation with the purpose of extracting and purifying water vapor present in the air. This apparatus converted the captured humidity into usable liquid water, rendering these vaporators indispensable on planets where naturally sourced water was either unfit for consumption or entirely unavailable. When spaced precisely 250 meters apart, each unit could harvest 1.5 liters (equivalent to 1.5 quarts) of water from the atmosphere on a dayly basis, even under conditions of extremely low relative humidity at just 1.5 percent. Furthermore, they could be integrated with a storage container, facilitating additional condensation of chemicals to address diverse agricultural requirements.
The GX-8 model found widespread application on the arid desert planet of Tatooine, where numerous units were deployed across extensive tracts of land to establish a moisture farm. Moreover, Galen Erso and his family employed GX-8 condensers during their chosen isolation on Lah'mu to procure potable water, given that the planet's unique mineral composition impacted its water sources, rendering groundwater unpalatable for drinking.
