mVAC Medical Vacuum Systems
mVAC-250 – mVAC-9200
A reliable source of medical vacuum
Atlas Copco’s mVAC Medical Vacuum Systems consist of 2 to 6 air-cooled, oil-lubricated rotary vane
type vacuum pumps and a central controller with an intelligent graphical user interface. The pumps can
work independently to satisfy the required vacuum flow.
mVAC systems are suitable for both continuous and frequent start/stop operation. They keep the
vacuum level at the point of connection as low as or lower than -600 mbar(e) (-450 mm Hg) at all times.
The mVAC system offers (multiple) backup supply in case of failure of individual functional components.
It is installed, piped and wired as modular stacked components or as a tank-mounted unit.
mVAC systems provide a highly reliable medical vacuum (suction) for a variety of applications, mainly in
operating theaters and intensive care, emergency and respirology units. Specific applications include:
• Wound drainage
• Assisted wound closure
• Chest and lung drainage
• Removal of excess blood during surgery
• Collection of other bodily fluids
• Gastric emptying
• Cleaning endotracheal tubes
mVAC-250 – mVAC-9200
• Liposuction (lipoplasty)
Ultra-reliable
A reliable source of medical vacuum is critical to patient safety. The carbon composite material of Atlas Copco’s mVAC pumps will not break
down or wear out like laminated blades. And if the central controller should fail, every pump still has its own controller. Every mVAC system
is subject to comprehensive Quality Assurance controls, is fully tested prior to dispatch and therefore ensures there will not be service
interruptions even in extreme circumstances.
Highly connectable
Up to six vacuum pumps can be connected in one mVAC system to ensure that even a large hospital always has a reliable vacuum to meet
all its needs. Further, using AIRConnect™ Visualization you can connect to extensive monitoring and status information to get the most out
of your mVAC system.
Cost-effective
Atlas Copco’s unique Elektronikon® control system gives you the means to effectively manage and optimize your mVAC system.
Device status is monitored in real time, required services are delivered rapidly, breakdowns can be prevented and downtime shortened. In short,
it provides all you need to keep operational costs to a minimum.
Easy to install

All interconnection piping and copper connections are supplied as an integral part of the mVAC system.

The “plug and play” approach makes installing even more easy.
Energy-efficient
At Atlas Copco we always strive to provide the most energy-efficient solutions. For the mVAC we have opted for a multi-pump arrangement
to better match the flow demand. In this arrangement, the advanced Elektronikon ® Graphic controller maximizes energy efficiency by
controlling the individual vacuum pumps and regulating the overall vacuum. Even wear is ensured at all times.

Quality components for a reliable vacuum
1 Vacuum pump
Atlas Copco’s oil-lubricated rotary vane vacuum pumps offer high flow capacities.
They are simple and economical to install and operate, and are quiet and vibration-free.
They provide smooth, pulse-free vacuum and have low starting and running torque.
The vanes are constructed from composite material for a long lifetime of use (up to
ten years under normal operating conditions) and low noise levels.
2 Motor
Optimally sized to suit the demands of
frequent starts found in medical applications,
each motor is air-cooled by an integral fan
and protected by an overload fitted within its
pump control panel.
mVAC™-250 – mVAC™-9200
3 Bacterial filter
The high-efficiency bacterial filter elements have a penetration of less
than 0.0001% when measured to BS 3928 to minimize the likelihood
of microbial contamination of the oil. Duplex filters are provided for
redundancy. The pressure drop over the bacterial filters is continuously
monitored by the central ES-VAC controller.
7 Vacuum vessel
The vacuum vessel is a mandatory back-up in the rare occurrence that all
vacuum pumps are down. It also acts as a buffer for peaks in the flow demand.
Its hot-dipped galvanized finish extends vacuum vessel life by 300% over
conventional untreated steel pressure vessels.
6 ES-VAC central controller
Developed specifically for medical vacuum applications, the ES-VAC
central controller is an intelligent microprocessor-based control system
dedicated to controlling up to six vacuum pumps in an mVAC system.
It is equipped with the 5.7-inch high-definition color display Elektronikon ®
Graphic+ module.
5 Pump controller
4 Tank-mounted variant
Tank-mounted mVACs are complete stand-alone assemblies with all components
and filters mounted on a single horizontal vacuum vessel. This configuration
provides a compact, low-footprint unit specifically designed for easy installation.
mVAC™-250 – mVAC™-9200
Each individual pump is equipped with a standard Elektronikon ®
controller that is linked to the advanced ES-VAC central controller.
Simple operation for high reliability
The vacuum pump at the heart of the Atlas Copco mVAC system is an oil-lubricated rotary vane vacuum
pump; one of the simplest and most reliable types of vacuum pump available.
Working principle
When the eccentrically installed rotor (1) rotates, the centrifugal force pushes vanes (2) towards the wall of the cylinder. The vanes create
spaces, or chambers, between the rotor and cylinder. When a particular chamber connects with the inlet channel, air is sucked in.
The sucked air is passing over a mesh filter (6) and non-return valve (7). This air is compressed by the next rotation and pushed into
the oil-mist separator (3). The differential pressure causes oil to be constantly forced into the compression chambers. The compressed air
is discharged through the air exhaust (5).

Measuring vacuum pressure
A vacuum is any pressure in a system that is less than the ambient atmospheric pressure. For medical applications the degree of vacuum
is not very high. However, there are two ways of measuring a vacuum pressure:


Bar(e) – the effective or gauge pressure – denotes how much the pressure is below local atmospheric pressure
Bar(a) – absolute pressure – denotes how much the pressure is above absolute zero vacuum.
Atmospheric pressure at sea level is approximately
1 bar or 1000 mbar. For typical medical applications
a vacuum of 600 mbar below atmospheric pressure
is required, which is denoted as -600 mbar(e).
From the illustration it can be seen clearly that this
value is also equivalent to 400 mbar above absolute
zero vacuum. It can therefore also be denoted as
400 mbar(a).
Atmospheric
pressure
Typical breathing air
4 bar
Atmospheric pressure
1 bar = 1000 mbar = 750 mm Hg
Note that because the measuring reference point
for bar(a) is fixed (absolute zero vacuum) while for
bar(e) it is variable (atmospheric air pressure),
a slight discrepancy can be obtained between the
two values. It is therefore important to understand
which type of reference is required before selecting
a pressure instrument for measuring the vacuum.
Typical medical vacuum
400 mbar(a) or -600 mbar(e)
= 300 mm Hg or -450 mm Hg
Absolute vacuum
0 mbar
