B-VIRUS FREE – Reliably removes viruses, bacteria and mould spores from your breathing air

  • Safe breathing air also in environments contaminated by pathogens
  • Reliably neutralises micro-organisms like viruses, bacteria and mould spores
  • Easy retrofitting of existing BAUER systems possible

Thanks to its innovative functionality, the B-VIRUS FREE protective filter makes sure that fire fighting and disaster control emergency forces, patients in compressed air chambers and even scuba divers are provided with pure breathing air – free of viruses, bacteria, mould spores and pollen.

The UV radiation of the fresh air taken in by the compressor inactivates any pathogens which can slip through the normally used intake filter due to their minimal size. The intake filters installed by BAUER are fine enough to stop normal dust particles and pollen which is already very small; yet viruses, bacteria and mould spores are several times smaller and as a result, they cannot be stopped by a conventional filter.

The UVC rays emitted by the UV light source inactivate these pathogens by destroying the DNA in bacteria and mould, and the RNA in viruses. Reproduction of the pathogens is therefore ruled out.

The short-wave UV light emitted generates no ozone thanks to the top-quality light source. Moreover, treatment with UV light means you are able to completely avoid any use of chemicals. Therefore, all roads lead to the B-VIRUS FREE when harmless breathing air is key, even in critical environments.

All the information you need at your fingertips!


The B-VIRUS FREE protective filter is ready for operation in no time at all. It only needs to be installed on a wall or equipment and connected to a 220/230 V (optionally: 110V) power supply. After just a few seconds of warm-up, functionality is fully guaranteed.

Intake filter

The fresh air is drawn in through the opening of the intake filter due to the vacuum of the compressor. Normal dust particles and even pollen from the air is removed already in the intake filter.

Source of radiation

With the help of the emitting high-energy UVC radiation, the special UV light source eliminates the bonds within the pathogens. That way, the DNA is destroyed in bacteria and moulds, and the RNA in viruses. Reproduction of the pathogens is therefore ruled out.

Control and display

For functional monitoring and control of the UV special light source, the device has a control box which provides visual and acoustic information about the operating status using LEDs and a beeper.

Connection to the compressor

The B-VIRUS FREE protective filter is connected to a specially sealed intake hose before the first compressor stage to exclude any possible leaks between the protective filter and the compressor block, thereby preventing repeated contamination.
