ZK2 is an all-in-one solution that incorporates: a supply valve, a release valve, a vacuum switch, a vacuum break flow adjustment needle, a suction filter and a silencer. Thus it provides you with immediate savings in installation and maintenance expenditure.
Furthermore, ZK2 is an energy saving solution that promotes efficient air consumption thanks to a 2-stage ejector which, in principle, increases air suction by 50% while reducing the air consumption by 30%. The consumption can be reduced a further 90% when choosing the digital pressure switch with energy saving function, which allows intermittent energising; i.e. the vacuum unit only gets activated when vacuum level falls below the desired value.
