”LAF canopies are the obvious choice when there is heightened risk of infection.”
Anders Walter, HVAC consultant, SWECO
“There should be a LAF canopy in every OR”
Angered, part of greater Gothenburg, saw the grand opening of a new community hospital in 2016. Powered by solar and geothermal energy, the goal was to build the most energy-efficient health facility in Sweden. That also meant finding a supplier of dependable and energy-efficient LAF canopies for three ORs. Project Manager Eva Lindblad recalls, “In my opinion, there should be a LAF-canopy in every OR. It’s safer for the patient and more flexible for the staff. In addition to canopies, CRC also provided HEPA diffusers for the infection unit.”
