When determining a single vacuum generator that will fit a variety of demands, whether it be varying weights, surface finishes or materials, the Adjustable E-Vacs can make quick work of the task at hand. This minimizes the number of parts needed for a variable product line. It also means each application can be adjustable as well. So why would this be needed?

Let’s look at a custom woodworking shop. They could be lifting slabs of lumber that may be rough cut, maybe they are lifting a smooth epoxy river slab, or even sheet of MDF. Each one of these materials will require some adjustment on the vacuum end. The reason being the surface finish and porosity of each material is considerably different.

MDF, expanded out as Medium Density Fiberboard is a common material for woodworkers to use. This material looks and feels smooth and fairly solid. The trick is, it is actually a porous material. You can hook a vacuum hose to one side of it and hold a piece of notebook paper to the other side because the vacuum flow will be pulling through the MDF. This presents a problem when trying to use vacuum to pick and place the board. You will need a higher vacuum flow in order to compensate for the leakage of air when pulling a vacuum. An epoxy coated slab on the other hand, is generally a smooth surface that is non-porous and will require less vacuum flow.

The greatest benefit to the Adjustable E-Vac is being able to easily adapt to meet the needs for both of these materials with a tool-free adjustment. A great example of this is in the video below.
