title: Achieving low germ concentrations.
abstract: The laminar outlet for operating theatres, presented here, which is being used to generate a laminar downflow, produces a very stable air pattern at air discharge velocities of = 0.15 m/s. Air flow tests show that the influence on air flow by operating lightings in the flow field is localised. Based on these results, recommendations can be made for the placement of operating lighting under the laminar outlet. Hygienic tests to DIN 4799 recorded relative airborne germ concentrations that comfortably meet the requirements of DIN 1946 Part 4, even at an air discharge velocity of 0.15 m/s.
