Flow velocity for process regulation
In the area of laminar flow below the ceiling filter (plenum)
In the exhaust duct
Laminar: 0.25 … 0.5 m/s
Exhaust air: 15 … 25 m/s
20 … 200 °C
In coating facilities flow velocity needs to be measured accurately at different points. Laminar flow has to be ensured in the spray booth to get optimal results and the exhaust air in the coating booth and the chamber kiln have to be monitored for safety and environmental reasons.
To achieve optimal coating results there have to be specific room conditions. Temperature, humidity and air flow have to be kept withing a strict range. Besides room conditions, environmental protection in coating and spraying also plays a major role. The resulting overspray in the spray booth is diverted by a regulated, downward-directed air flow. Said air flow is collected, measured and processed. The exhaust air of the chamber kilns is also measured. That way environmental pollution is reduced. It also ensures that no harmful or flammable concentrations of solvents arise.
