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