Macrospray® nozzles produce consistent mists at very low pressure. The nozzles have a uniformly distributed droplet size (10–30 μm Sauter Mean Diameter), which provides greater contact between deodorant, for example, and odorcausing particles or dust. Droplet size can be tuned for the degree of dust particle interaction and “knock-down” required. The nozzles provide multiple tips for high flow.The devices also have flow features chemically etched into bonded substrates, resulting in a monolithic structure. Nozzle passages, including metering slots, spin chambers, and exit orifices, are designed to minimize pressure drop to conserve pump energy. Hydraulically smooth internal surfaces reduce flow losses.
