The most popular use for our Electronic Flow Control units is for an intermittent operation for blow off. This would be jobs such as computer monitors that need the screen blown off as they are coming down a conveyor belt. While this is ideal for the EFC there are other ways you can use this compressed air saving device.
One way would be for part ejection. This would be a case where maybe some pieces are taller than others and so you want to blow off the tall parts into a bin. Simply set the sensor at the height just above the height for the short product and then every piece that is above that height will trigger the sensor and blow it off the line.
Another use would be to tell when a hopper that is being filled by a Line Vac is empty or over filled. You can adjust the sensor and the control module to sense that the hopper is empty and it will turn the compressed air on to the Line Vac to then feed the hopper. Then set the timer module so it will run for the length of time it takes to fill the hopper. The other way would be to place the sensor at the top of the hopper and have it sense when the pile of media has reached the full level.
As with many of the other EXAIR products the Electronic Flow Control offers a solution to more than just one application.
