Air Atomizing NozzlesSpangling/Cold Strip MillVariable Spray Air Atomizing OptionsAllow Fine-Tuning of Spray PerformanceOur VAU and VMAU Air Atomizing nozzles allow you to adjust the atomizing air, fanair and liquid flow independently. For example, you can reduce the atomizing air toproduce a larger drop size. Or, you can adjust the fan air line to regulate the spraypattern and coverage without affecting the drop size or flow rate. Independent controlof the liquid flow also allows you to achieve various distribution patterns withthe use of just one nozzle. An additional inlet/outlet port allows for liquid recirculationthat effectively maintains the flow of viscous liquids such as oils.The VMAU allows for a slightly finer adjustment of the spray for applications requiringhigh precision. It also features a modular design approach for maximum flexibility.Other unique features of the VMAU include:• O-ring sealed air cap on the fluid tip for positive alignment and sealing• Patent-pending modular body and threadless fluid tip design• Available with anti-bearding set-ups• Use of a baffling system for supplying the atomizing and fan air. This system distributesboth the fan and atomizing air equally, providing a more uniform spraypattern.Current VAU customers can easily change to the VMAU since the centerline distanceand mounting thread is the same on both nozzles.VAU nozzles are available with seven different spray set-ups with flows rangingfrom 0.74 to 47 gph (2.8 to 179 l/h). For complete performance data, request datasheets 37459-V67B, 37459-V67A, 37459-V67, 37459-V113A, 37459-V113, 37459-128and 37459-V152.VMAU nozzles can utilize any of eight different spray set-ups that provide flow ratesranging from 0.74 to 73 gph (2.8 to 276 l/h). The following chart provides liquidcapacity data for each of the available set-ups.
