Washer 29154-001-BUC Shut-off/clean-out needle assembly 29534 1/8VAU Features and Benefits • The VAA, VAU and VMAU variable spray nozzles provide uniform spray distribution, even when spraying viscous liquids. • Independent control of liquid, atomizing air, and fan air pressures is possible for fine-tuning of flow rate, drop size, spray distribution and coverage. • Can be set and re-set in seconds, simplifying application changes. • Independent air atomizing line can be adjusted to vary spray drop size without affecting liquid flow rates. • Additional inlet/outlet port allows for liquid recirculation that effectively maintains the flow of viscous liquids. • VAA offers continuous operation and consists of a body, spray set-up and plug. • VAAN features a manual shut-off needle that enables the flow of the liquid to be stopped. • VAACO features a clean-out needle that clears the liquid orifice of obstructions when activated manually. • VAANCO combines the features of the VAAN and VAACO, offering a combination shut-off/clean-out needle. • VAU offers automatic operation with a built-in shut-off/clean-out needle. • VAUPM has the same operating features as the VAU, but offers the convenience of a mounting plate. • VMAU allows for individual adjustment of the atomizing air, fan air and liquid flows and offers modular components to accommodate a wide range of spray applications. • Mounting Kit 28945-001-316SS uses clamps to mount VAA nozzles. • Mounting Kit 28945-002-SS uses rods to mount VAA nozzles.
