SUCTION MOTORS

Wet, liquid and dry. Let’s go see the differences and when we can install one of them!

LIQUID SYSTEM
It’s the old version of the wet suction motor. The main difference in this machine is that it needs a water supply to work. The consumption of water is very high, and for this reason, we don’t use it anymore.

DRY SYSTEM
In this suction system, only air arrives at the motors; we can not put water or fluids inside it. It does not need any pipe for the drain: if you have a machinery room without a connection to the waste net, this is a good solution!
Another advantage of this system is that can be installed in an upper position compared to the dental unit. A wet suction system can not be installed on the upper floor: it does not have enough power to bring the fluids upward. But if the suction motor works only with air, this is possible!
This kind of system also needs an air/water separator: if it can not vacuum fluids, they must go somewhere! The air/water separator can be installed at the chair base, and we can install the CS1 made by Dürr.

WET SYSTEM
We recommend installing the wet suction motor every time it is possible. It has many advantages: no valves are required, it costs a bit less, and the consumption is similar to the dry suction system. It’s the best choice in our opinion!
We said that it does not need any kind of valves, but it can work with a selection valve or a spittoon valve, but this is a different topic explained in this video.
When you install this kind of system, a drain pipe in the machinery room is required: it vacuums not only air but also fluid that needs to be wasted.

MAINTENANCE
While the dry suction system does not need any kind of maintenance, the wet one needs two interventions: cleaning the filter and using an anti-foam solution in order to keep the performance high.
The maintenance is very easy; it is a very simple system. We recommend this every day during an intensive work day or, at least, every week.

HOW DO I RECOGNIZE THE TYPE OF MY SUCTION MOTOR?
If you need to replace the dental units inside your clinic, we need to know what kind of motor you have, in order to install the proper valves (if needed). How do we recognize them?
DRY SUCTION: It does not have a drain pipe.
WET SUCTION: It has a drain pipe.
LIQUID SUCTION: It has a drain pipe and also has a water tube connected to the head of the motor.
When toy know this information, we can build up the configuration of your new dental units.
