6. PRODUCT DESCRIPTION

6.1. Model variations and their uses
Dental suction unit DO 2.1 - is the source of vacuum to provide suction in the dental surgery – aspirates
waste from the patients mouth - via a tip connected to the cannule of the suction hose, through the
pneumatic control module and down to the separator, where the water and foreign matter is left behind,
leaving only air to be drawn (sucked) to the suction unit and exhausted away from the surgery's
environment.
Dental suction unit is composed of an aspirator unit with a base, cooling fan, switching block and an
insulated soundproof box. Operation of the suction unit is controlled via (24V/0.1A DC/AC) connection at the
chair or via a switch on (model „T") at the suction unit. Cooling fan draws air into the box and circulates it
around the suction unit forcing air out through ventilated slots in the rear.
Dental suction units are made accordingly for the purpose in the following versions:
DO 2.1, DO 2.1-10 – stationary dental suction unit in a soundproof box – it serves as the source of vacuum
for the dental chair fitted with a pneumatic control module. The suction unit will start automatically after
receiving a signal from the chair – by a 24V AC/DC connection between the chair and suction unit.
Soundproof box is provided for silent operation.
DO 2.1 T, DO 2.1-10 T – model as at DO 2.1 above, switch from unit controlls suction pump by voltage from
module „T".
DO 2.1 Z, DO 2.1-10 Z – stationary dental suction unit without the soundproof box – it serves as the source
of vacuum for the dental chair fitted with a pneumatic control module. The suction unit will start automatically
after receiving a signal from the chair - by a 24V AC/DC connection between the chair and suction unit.
DO 2.1 TZ, DO 2.1-10 TZ – model as at DO 2.1 Z above, switch from unit controlls suction pump by voltage
from module „T".
Dental suction units above designated as - DO 2.1-10, DO 2.1-10 T - are different from the other
ones only by their dimensions and weight, so that they complied with the design of compressors -
DK50-10 S type.

DESCRIPTION OF FUNCTION

Suction pump (1) (Fig.1) creates vacuum in the
pneumatic control module thus it aspirates foreign
matters away from the working area of the physician and
sucks them into the separator at the dental chair. Only
clean air continues past the separator through the pump
of the suction unit, and then, is pushed through a
supplementary silencer (6) and continues through the
output hose and vented to the environment outside of
the building. Suction unit is switched on by means of a
switching block (3) after receiving a signal from the
dental chair (voltage 24V AC/DC) or by switching-on at
the suction unit (switch - model „T"). Suction pump is
mounted above the cooling fan (4)which is fixed to the
base (5). The cooling fan draws air into the insulated
soundproof metal box (2), which stands on feet to allow
the air in, and vented slots in the rear to allow the air to
blow through.
Make sure that nothing impedes the free flow of air under and around the compressor.
Never cover the hot air outlet on the top back side of the case.
If placing the appliance onto a soft floor, such as carpet, it is important to create a gap
between the base and floor or the box and floor, e.g. underpin the footings with hard pads.
The cooling fan needs a gap to draw air inside the box.
