BaseVac is constantly asked why our vacuum is so powerful. Our reasoning? Dentists like the BaseVac system because it is strong. We also say the extra suction power ("Hg, inches of mercury) helps to balance the load with multiple user clinics by sucking more air out of the system when the hand tools are throttled or temporarily not in use.
If we set our vacuum regulating valve at 12"Hg (everyone's best vacuum) the volume of the pump
would remove air from the system up to the 12" Hg vacuum level. After that, the vacuum relief
valve opens and the pump starts sucking air from the suction piping and the utility room. When the Dentists start to require suction again, the valve will slowly close until the pump volume equals the
volume allowed to enter the suction tools being used. At this point, "perfection."
What can happen is that more users come online with more open suction tools and the vacuum
energy level drops. This happens because the pumps capacity to suck air (volume) is not big
enough to keep up. In reality, the Dental suction system now fluctuates from perfection to very low
and back to perfection. We call this "less than perfect fluctuation."
Putting BaseVac into Perspective
At BaseVac, we have a vacuum pump that can create 25"Hg suction power. It does this by
sucking more air out of the piping system beyond the perfect point of 12” Hg. The vacuum relief
valve stays closed; no air is sucked out of the utility room. We call this "stored volume." To make it
easier to visualize the benefit consider this:
- ln a system set of 12"Hg, the vacuum empties the piping system of air so you can fill it with
the air you evacuate through your suction tools. The air and liquids enter the empty space if space is
available.
- Consider your system as ten empty bags waiting to be filled up to 12” Hg then the pumps
stops filling for you. The "less than perfect fluctuation" occurs while the pump is trying to empty
more space for you to fill.
- The stronger the vacuum the faster the air moves into the empty space. Velocity (speed)
helps to move liquid and particles.
- The BaseVac system gives you empty space on both sides of "perfection." The second a user stops using the system even for a few seconds the BaseVac system keeps sucking air making more space for others to fill. This causes the vacuum to rise higher than 12”'Hg emptying more bags to fill. If no one requires suction for a few minutes the vacuum energy level can rise to 25"Hg before our valve opens and sucks air from the utility room. We have however already created empty bags on both sides of 12"Hg (perfection); sucking air from the utility room of this point does not affect the fluctuation of flow.
So, when BaseVac can empty bags on both sides of perfection, a multi-user clinic can achieve
"greater than perfect fluctuation" or stored volume. Of course, it is possible that a single user in a multiple user clinic may, for a short time, have very strong suction but rarely for very long. If it is a
small clinic it is smart to set the vacuum relief valve of a vacuum level of 12” Hg “perfection" if you
and a few others are the only ones filling the empty bags; you can predict the volume of air you
need and set the vacuum relief valve accordingly.
What the BaseVac system is intended to do when it is delivered set at 25"Hg maximum suction
is allow you to set your comfort level of fluctuating suction and fluctuating flow. It gives you the
option of setting and maintaining your individual level of "perfect fluctuation." BaseVac Dry Dental
Suction system is the only dental suction on the market that offers this unique advantage.
