Aerators for medical facilities

Working together with BZH GmbH (German Consulting Centre for Hospital Epidemiology and Infection Control) in Freiburg/Breisgau, Neoperl GmbH in Müllheim has spent several years conducting various laboratory tests at the Ruhr District Institute of Hygiene and the Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM) in Hannover, as well as carrying out literary research.

In June 2016, the BZH compiled an expert report on the subject of aerators in water outlet points in medical facilities, taking into account the results of the laboratory tests.

Based on the expert report from the BZH, the Neoperl Group issues the following recommendations for aerators in medical facilities (hospitals/ nursing homes)

1.  In medical facilities, aerators help to prevent water unintentionally landing on surfaces and splashing. This means they reduce the risk of pathogens being transmitted.

2. Although the expert report shows that traditional vented aerators do not present a significantly higher risk of infection through inhalable pathogens, we recommend using laminar flow aerators. These almost completely prevent the intake and distribution of contaminated aerosol particles.

3. Various environmental factors in a medical facility can lead to biofilm growth on an aerator. We therefore recommend replacing them regularly. Exactly how often the aerators should be replaced is up to the individual medical facility, but Neoperl's colour coding system can help to remind staff when it is time for a replacement.


The Clinic aerators were developed based on these three factors.
