Application
Vacuum pumps for anaesthetic gas scavenging
In anaesthetic gas scavenging, a vacuum pump draws off the anaesthetic gas that escapes from the patient’s breathing circuit and removes it from the operating theatre. Busch describes the task as removing anaesthetic gas from breathing circuits, Elmo Rietschle as gas removal in the operating theatre (AGSS). Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it – 133 models from 1 manufacturers.

In short
Anaesthetic gas scavenging: the key facts
- Breathing circuitsBusch describes anaesthetic gas scavenging as removing anaesthetic gas from breathing circuits and names it for hospitals and healthcare facilities.
- AGSSElmo Rietschle lists the application as anaesthetic gas scavenging (AGSS) among its medical applications: gas removal in the operating theatre.
- SeriesBusch names the series MINK, DOLPHIN and SAMOS as well as its hospital vacuum system MEDIVAC, which is not a series of its own in our range. Elmo Rietschle lists the application without a series.
- SizingThe pump must be able to draw off the gas of all connected anaesthesia machines at the same time; we determine the pump size with you based on the number of connection points.
Operating principle
How it works: Anaesthetic gas scavenging
The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.
- CaptureThe anaesthetic gas escaping at the breathing circuit of the anaesthesia machine is captured. Busch describes the task as removing anaesthetic gas from breathing circuits.
- ExtractionThe negative pressure of the vacuum pump draws the gas through the extraction line; the separator and filter retain liquid and particles.
- DischargeThe pump discharges the gas via the exhaust air out of the operating theatre. Elmo Rietschle calls the application gas removal in the operating theatre (AGSS).

Frequently asked questions
Anaesthetic gas scavenging: frequently asked questions
How does anaesthetic gas scavenging work in the operating theatre?
The anaesthetic gas escaping at the breathing circuit of the anaesthesia machine is captured and drawn through an extraction line to the vacuum pump. A separator and a filter retain liquid and particles, and the pump discharges the gas via the exhaust air out of the operating theatre. Busch describes the task as removing anaesthetic gas from breathing circuits, Elmo Rietschle as gas removal in the operating theatre.
Which vacuum pump is suitable for anaesthetic gas scavenging?
For anaesthetic gas scavenging, Busch names its series MINK, DOLPHIN and SAMOS as well as the hospital vacuum system MEDIVAC. MINK are claw vacuum pumps, DOLPHIN liquid ring vacuum pumps and SAMOS side channel blowers. Elmo Rietschle lists the application among its medical applications but names no series.
How much vacuum does anaesthetic gas scavenging need?
The pump must be able to draw off the gas of all connected anaesthesia machines at the same time. We determine the right pump size with you based on the number of connection points in the building.
Oil-free or oil-lubricated for anaesthetic gas scavenging?
The series that Busch names work without oil in the pump chamber: MINK are dry-running claw vacuum pumps, DOLPHIN liquid ring vacuum pumps with water as the operating liquid and SAMOS side channel blowers.
What does AGSS mean in anaesthetic gas scavenging?
AGSS is the English abbreviation for anaesthetic gas scavenging (Anaesthetic Gas Scavenging System). Elmo Rietschle lists the application under this name, as anaesthetic gas scavenging (AGSS), and describes it as gas removal in the operating theatre.
Why must anaesthetic gas be scavenged?
Anaesthetic gas escaping from the breathing circuit would otherwise accumulate in the room air of the operating theatre. Busch therefore describes the task as removing anaesthetic gas from breathing circuits, Elmo Rietschle as gas removal in the operating theatre.
Which manufacturers name anaesthetic gas scavenging?
Busch names it for hospitals and healthcare facilities with the series MINK, DOLPHIN and SAMOS, Elmo Rietschle among its medical applications without a series.
What can be done if condensate builds up in the extraction line?
Between the line and the vacuum pump there is a separator for condensate and entrained liquid and a filter for particles. This way only gas reaches the pump.
A single pump or a central vacuum system?
A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group – more under Central Vacuum.
Does Ehrler & Beck also supply spare parts and service?
Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
