SUCTION TECHNOLOGY  Suction Technology

Asco

Suction equipments are used in situations where not only perfect reliability is absolutely vital but also where the economical and ecological aspects of healthcare are of major concern. In order to meet these ever-increasing demands to an even better degree, we have developed an innovative suction, cleaning and disinfecting concept based on high-quality suction technology.

What is Vacuum?
Asco
The earth's atmosphere exerts a pressure upon us, known as the atmospheric pressure, which can be measured in a number of ways. At sea level the standard pressures is 14.7 psi or 29.92" of mercury (Hg) or 760mm of mercury (Torr). Because the barometric pressure varies, the above sea level pressures are used as a reference point.

When using the term "Vacuum", "negative pressure" "suction" etc. we mean a pressure that is lower than atmospheric pressure.

Expression and Unit
Asco
In everyday speech there are many different expressions and units for pressure below the atmospheric pressure.

Some of the common units used in connection with vacuum and their inter relationship is given in the table below.
