Why the VAL?
The innovative nature of the vacuum airlift comes from the addition of a vacuum to an airlift. Compared to existing technologies, the result is a major improvement both in efficiency and energy consumption for each function of this process. Total energy cost savings range between 3X to 8X versus currently used competing systems. In addition, VALs are constructed of durable materials; they require little to no maintenance; the process uses no polluting material; and they provide added safety by distancing all electrical and mechanical equipment away from the operation.
