– Acoustic Box and Air Compressor
5.3.1 Air Compressor and Acoustic Box
The Vet Cart Premium has a noise-reducing acoustic box
(1). The manometer (2) and the digital voltmeter (3) – which
will indicate the voltage (Volts) received by the equipment
through the power supply - are on the front of the box.
Internally, the acoustic box is revested with insulating
foam and accommodates the compact air compressor (4),
which will supply the pneumatic instruments and the saliva
ejector necessities of compressed air.
The compressed air tank is the column and base (5) of
the equipment, and it has a drain (6) and a safety valve (7).
The compressed air outlet has a pressure regulator (8)
that allows the reduction and cut off the airflow. For this
adjustment, simply turn the valve clockwise to reduce or close
the flow and counterclockwise to open.
The door lock (10) and two coolers (9) are
accommodated on the acoustic box door; two fuse holders (11)
and the power supply input (12) are in its structure. The water
tank (13) and the sewage tank (14), shown in the 5.1 section,
are accommodated inside the acoustic box too.
Reducing the airflow in the automatic drain
adjustment valve can impair the performance of
pneumatic and saliva ejector instruments.
5.3.2 Air Tank Drainage
The air tank drain is a preventive procedure, which avoids the moisture
accumulation, the automatic drain clogging and consequently a drop in the
performance of pneumatic and saliva ejector instruments.
To drain the air tank: with the air compressor turned off, open the air tank drain
valve (15) by turning it counterclockwise. Leave the hose outlet free to let out the
debris/water until the tank is clean. Close the air tank drain valve (15) at the
operation end, by turning it clockwise.
Note: When the equipment remains “ on ” for a certain period, it is
recommended to drain the tank daily.
5.3.3 - Pressure Regulator for Instruments
The pressure regulator for instruments has a filter (6) for blocking the moisture of the
compressed air and a pressure relief valve (8) to protect the equipment’s pneumatic system.
It is installed on the equipment compressed air outlet.
Its function is to regulate the pressure supplied to the handpieces and to filter, to avoid
dirt on the instruments
Automatic drainage occurs whenever the compressed air network is depressurized or
reaches a pressure of less than 30 PSI, preventing the instruments from working properly.
