air cleaning devices
Services
VirexpR is specialized in the generation of atmospheres contaminated by infectious respiratory viruses or complex mixtures of pathogens (viruses, bacteria, molds) in large volume experimental test benches dedicated to the performance evaluation of air treatment technologies and devices in experimental conditions mimicking different real environments.
Proven methodologies and logistics allow the implementation of :
Our test benches
- Generation of highly contaminated atmospheres with infectious respiratory viruses and complex microbiological mixtures (viruses, bacteria, molds)
- Evaluation of the performance of air treatment devices and technologies according to the intrinsic devices parameters
- Possible configuration in “one-pass” mode
A complex test bench of 20m3 to characterize the performance of air treatment devices, bio-collectors and biosensors under experimental conditions that mimic different real-life environments :
- Generation of atmospheres contaminated with infectious viruses and complex microbiological mixtures (viruses, bacteria, molds)
- Option : supplement the nebulisation solution with biological fluids : saliva, mucus, …
- Variation of aerodynamic parameters : integration of different operating modes in the test bench : classroom, office, cleanroom, …
- Evaluation of the performance of air treatment devices against contaminated atmospheres in infectious viruses or in complex microbiological mixtures
- Evaluation of the performance of biocollectors and biosensors : harvest, detection and identification of viruses, bacteria, and molds in contaminated atmosphere with microbiological mixture
- Determination of deployment and operating mode in situ of air treatment devices
- Determination of deployment mode in situ of bio-collector and biosensors
A “one-pass” test bench consisting of an air stream 60 cm square and 800 cm long to characterize the performance of air treatment technologies or devices integrated into the ductwork of industrial ventilation systems (pharmaceutical, livestock, building public access, etc.).
VirexpR has designed this test bench in line with ISO 15714:2019 recommendations, and has adapted it to handle aerosolized infectious viruses.
The technical specifications of this air stream make it possible to:
- Modulate and monitor flow velocity (flow rate up to 3000m3/h)
- Perform upstream nebulization of infectious virus suspensions (class 2 and class 3) and mixtures of pathogenic microorganisms (bacteria, molds, phages, etc.),
- Perform downstream bio-collection and quantification of residual viruses and infectious microorganisms
- Evaluate in a single pass the performance of technologies (filters, UV, photocatalysis, etc.) and air treatment devices integrated into the ducts of industrial ventilation systems (pharmaceutical, livestock, building public access, etc.).
VirexpR also offers a custom engineering service to adapt the technology or air treatment device to be evaluated for integration between the two sections of the “one pass” test bench.
