ZK2, Vacuum Unit, Ejector System with Valve
[Features]
· Built-in digital pressure switch for vacuums, with energy-saving function. Cuts the air supply upon reaching vacuum: Leading to 90% reduction in air consumption
· Has a 2-stage ejector structure that increases suction flow rate by 50% and reduces air consumption by 30% (compared to SMC's single-stage ejectors)
· Compact and lightweight, with a 28% reduction in volume (88 cm3) and a 59% reduction in weight (81 g) compared to conventional products
· Reduced wiring for single units as well as manifolding.
· Once the supply valve is switched ON, the vacuum generation state is maintained even if the power is cut off. This reduces power consumption.
