Introduction

The "Dry and semi-dry centralized systems" handbook is meant to offer our guidance and
help to designers and engineers as for piping size and type of appliance. In case this booklet
should not be exhaustive, our design department, in our headquarters in Italy, and all
concessionaries abroad are willing to supply any advice and to design any plant.
In order to avoid any misunderstanding we believe it is useful to clarify the meaning of dry,
wet and semi-wet systems.
• In a dry system, only air runs through the aspiration pipings and the aspiration unit cre-
ates vacuum by an air ring vacuum pump.
• In a wet system the fluid running through the aspiration piping is composed of aspirated
liquids and air, while the ring inside the pump is created almost totally by an independent
water supply.
• In a semi-wet system both the above systems are combined: inside the aspiration pipings
flow the aspirated liquid plus air (like in a wet system) while the aspiration unit is an air-ring
one.
Briefly:
• in the dry version, only air flows in the piping and in the pump;
• in the wet version, liquids flow in the pipings and in the pump;
• in the semi-wet version, liquids flow in the pipings and air through the pump.

General features

Dry centralized plant are particularly suitable for dental surgeries where the main practice
is prosthetics. Anyway they allow for small surgery operations.
For parodontal and maxillo-facial surgery wet ring pumps and semi-wet systems are more
advisable.
Semi-wet dental aspiration systems are suitable for both surgery and prosthetics; recently
introduced in the dental field, they have low operating costs. There are however some
installations difficulties: counterslopes cannot be easily overcome if not to only a minimum
extent; separator tanks (necessary only for large plants) must be installed at a level below
the floor where the aspiration pipings run: this rule does not include the A 60 tank which can
be installed at the same level as the dental unit.

The aspiration units of semi-wet systems basically comprise, an air ring fan, a centrifugal
separator and a control panel. They are available with or without box, dimensions fig. 33a-
33b-34a. There is a soundproof version available for each model.
As for other parts (shutting valves, tip supports, amalgam separators, etc.) they are the
same used in dry or wet systems and can be used the same way.
