Electric Air Admission Control (EAAC)
The Electronic Air Admission Control (EAAC) admits air into the vacuum main independently of the controller. The EAAC acts on a preset time interval and vacuum levels in the main. It is used to improve performance of the system.
The EAAC can be installed in vacuum valve collection chamber or its own in a bespoke manufactured air terminal post. The EAAC is designed to assist vacuum mains were the injection of air is required to assist in propelling the sewage along the vacuum main and improving the vacuum system performance.
