Overview of UltraPierce Vacuum Assist
Component ID
How it works
UltraPierce Vacuum Assist works on a simple principle—create a vacuum in the cutting head, then
use this vacuum to draw abrasive into the mixing chamber before turning on the high-pressure
water.
A compressed air-driven eductor supplies the vacuum, and a pinch valve opens and closes the port
that connects the educator to the cutting head. The system uses a vacuum to remove the abrasive
pulled through the head by the vacuum eductor.
When the vacuum assist is off, there is no air supplied to the eductor. However, air is supplied to the
pinch valve in order to close it and isolate the chamber. When the vacuum assist is on, air is
supplied to the eductor to generate a vacuum. No air is supplied to the pinch valve, allowing it to
remain open.
