The AcornVac pneumatic control system is a low cost alternative to vacuum valve operation and control. The system includes pneumatic controllers which are used to operate the waste extraction valve. The valve controller is non-networked and is powered by vacuum pressure from the system, and thus requires no electrical service.
Low cost
Vacuum powered – no electrical service required
Pneumatic Controller includes manual activation button and adjustable valve control timing
When the flush pushbutton on a toilet is pressed or when a change in pressure occurs at the accumulator, a pneumatic signal is received at the Controller. When this signal is received, the Controller uses vacuum from the system to open the waste extraction valve for a pre-set period of time sufficient to remove the waste from the accumulator or the toilet. Once the cycle is complete, the waste extraction valve closes. The Pneumatic Controller includes a timing mechanism that can be field adjusted.
