ASPRA validation COVID department
To improve the room conditions in the Bed boxes in a Dutch Hospital COVID-19 Department, a VFA ASPRA 11010 (ASPRA Ceiling) unit was installed above the suspended ceiling. The purpose of this measure is to reduce the increased particle concentration in the room. An Induct ASPRA unit has also been placed. This is to remove the particles from the extracted air.
The installed ASPRA units have been validated by Modderkolk Projects & Maintenance for:
- Flow rate measurements ASPRA unit and the existing air diffusers
- Pressure measurement
- Particle measurement under ASPRA unit
Below, the summary of the findings can be found. Measurements were carried out in two places.
