Wet or dry?

We know that there are generally two types of suction: wet suction and dry suction. But when should you install a wet system, and when a dry one?

Advantages of wet suction systems:

  • Central amalgam separation is relatively easy to implement on a wet suction system.
  • With more than three dental units, a wet suction system is more attractive

Disadvantages of wet suction systems:

  • The pipe installations are more complex on a wet suction system. It needs to be considered whether the suction pipes are already present in the surgery and how they are designed because in some cases, a new pipe installation is required for a wet suction system.
  • The suction unit can only be installed on the same floor as the surgery or in the cellar below (but not on a floor above).

Advantages of dry suction systems:

  • Dry suction systems offer simple line routing and flexible installtino options fo the suction motor.
  • With dry suction systems, the suction units can also be installed on a floor above the surgery
  • Disadvantages of dry suction systems:
  • An air/water separation unit, possibly with an amalgam separator, must be installed in the treatment unit.
  • With more than three treatment units, the dry suction systems are more cost-intensive.

Questions that should always be asked before making a decision

  • What are the existing treatment units primarily set up for? A dry suction system or a wet suction system?
  • If necessary, is it possible to convert the treatment units?

Because: The construction requirements of the suction line network and the possibilities for conversion often determine the choice of possible system.
