8. PRODUCT DESCRIPTION
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.
8.1. Variants
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.
