The New Way low flow air bar provides FPD manufacturers with non-contact control of Flat Panel Display or Photovoltaic glass, optimized for applications with low airflow requirements.
The difficulty with high fly-heights of greater than 50 microns is that they typically result in low air film stiffness (less control) unless they also have correspondingly high pressures and flows. By plumbing most of the porous media face with low pressure air, and with high pressure air only around the vacuum holes, the flow requirements are greatly reduced. This is how New Way low flow air bars are designed. The periodic high pressure areas, preloaded by the vacuum, create high stiffness points which stabilize the glass dynamics even at high air gaps and low air consumption. And because the pressurized air bleeds out of the entire bearing face it provides a high margin of safety against glass touch-down.
In addition to the standard low airflow product line (shown), custom air bars are also available. Just contact the New Way Sales Department. |
