The SMP provides a complete integrated vacuum solution using optimized venturi nozzles (5 sizes), control solenoid valves for turning on/off the compressed air, solenoid valves for converting suction to blow-off, vacuum switches, safety check-valves, filters and silencers. During "blow-off" mode, an internal piston diverts 100 percent of the compressed air supply through the vacuum port to create the fastest workpiece release times possible. Three types of vacuum switches can be directly mounted, ranging from a simple electro-mechanical switch to a programmable dual-output electronic switch with digital display for viewing vacuum pressure.
