MdB Henke takes a close look at the PV1000

MdB Henke has also heard about our project and now wanted to see the progress of our PV 1000 production with his own eyes. 

Soon to come! – 10 new PV1000

Our small manufactory-like production of the next 10 units is now in the final stage

May 2021

In the final stages of small series production

With the help of the Institute of Welding and Joining Technology (ISF), we are now in the final months of production of the next series.

March 2021

Next small series starts

The work for the next small series has started. For this series several devices are planned which will be used by the RobinAid Foundation for training purposes in Cameroon.

February 2021

Many thanks to the Aachener Nachrichten for this well-done article about our project and the #PV1000.

November 2020

Local media reports on the progress of the project. While the project team is now preparing the small series.

The first prototype is completed and is now being prepared for intensive testing

Oktober 2020

Meeting with RobinAid to be able to deliver ventilators to Cameroon.

The wiring harness is implemented. This will allow communication between all sensors, processors and actuators.

September 2020

Assembly of penumatic components for the first two prototypes.

Final design of the GUI software, supported by Beger Design.

August 2020

Final design of the placement of the internal components, GUI and 5. The positive influence of Beger Design, who joined the PV1000 team at the end of June 2020, becomes visible.

July 2020

The injection mold for the check valve is ready (IKV).

The graphical ware unboxing. The first 10 PHYTEC displays arrive in Aachen.

2nd integration workshop as a kick-off event for the assembly of all components to build a functioning ventilator.

Start of field testing with a clinician providing feedback on our PC-based GUI simulation (led by Dr. Janss and colleagues, meditec)

Juny 2020

4th iteration of the housing concept to optimize clinical ergonomics.

3rd iteration of the housing concept, now considering dimensions and placement of all internal pneumatic components. Philip Guthausen from IKA is now responsible for the mechanical design.

May 2020

The control unit of the PV-1000 is completed within a month by fka GmbH and ika ́s team.

The specification and development of the graphical user interface (GUI) software is a continuous process enabled by ZOOM. The software project manager is Dr. Stollenwerk (i11).

WDR Lokalnachrichten Aachen. Demonstration of the prototype case

A team from fka GmbH and ika ́s start work on the PV-1000 control unit.

The 2nd iteration of the housing design is actually 3D printed and assembled (S. Lyra and J. Rixen)

The project becomes visible on social media and donations can be made via

The new project website goes online and gives a good overview of the progress of the project and supporters the opportunity to donate .

April 2020

Foundation of AC4Health gUG as a legal entity to accept donations and enable production. Dr. Marian Walter and Dr. André Stollenwerk are appointed as managing directors.


The device name PV1000 is defined and the first prototype design is released.

First successful volume controlled ventilation with single components and rapid control prototyping.

Material selection for PEEP valve and check valve. Design and manufacture of injection mold at IKV.

Successful volume controlled ventilation with single components and rapid prototyping.

First sensor and component tests at the end of March and beginning of April 20

March 2020

Call of Duty. Recruited approximately 50 volunteers from electrical engineering, mechanical engineering, computer science, and medicine to work part-time on the device (see

As a consequence, Professors Leonhardt (MedIT), Eckstein (IKA/fka), Kowalewski (i11) and later Radermacher (meditec) reached an agreement to join forces to develop and build a simple ICU-quality pandemic ventilator.

Germany was shocked by the COVID-19 lockdown and witnessed the overwhelmingly sad news from Bergamo in Italy and other parts of the world. Among other problems, the lack of a sufficient number of artificial ventilators caused worldwide concern.
