The 63600A Series of automac air atomizing manifolds is a system of customizable manifolds of nozzles for spraying a
multude of liquid materials, including paints and lacquers, greases, release agents, corrosion prevenves, adhesives,
and ceramic glazes. A complete nozzle assembly consists of a uid nozzle and air cap installed into a body which is per-
manently axed to a manifold weldment.
Addionally, the 63600A manifolds are specically designed to also spray a wide variety of food ingredients, such as
oils, syrups, slurries, chocolate, and peanut buer. The 63600A manifolds operate on the principle of pneumac atomi-
zaon (also commonly referred to as 2-uid atomizaon), where liquid is discharged from the nozzle orice and then
atomized with compressed air, nitrogen, steam, or other pressurized gas. The spray paern is then further shaped by
paern or fan air, which impinge on the atomized spray. The 63600A manifolds of automac nozzles are air controlled,
operang in conjuncon with a 3/2-way control valve.
The 63600A manifolds are provided with an integrated hot water jacket for uid temperature control. The manifolds
contain only food grade materials of construcon and are type 316 stainless for corrosion resistance. The manifolds are
provided equipped with either Type J or Type VMA air atomizing set-ups. Manifolds may be eld converted from one
nozzle system to the other.
Manifolds can alternavely be constructed in a radial (“deadhead”) or recirculang arrangement. The liquid volume is
ulmately controlled by the nozzle orice size and supply pressure, however the nozzles are supplied with an adjusng
knob for individual control. The adjusng knob throles the orice from fully open to completely closed.
3.1 AIR CONTROL
The 63600A manifolds are available with or without integrated air control. When equipped, the nozzle will shut-o the
atomizing and fan air when closed. Actuaon of the control valve directs air into the cylinder chamber of the nozzle so
as to open, in sequence, the atomizing and fan air, followed immediately by the liquid. Upon closing the control valve,
this process is then reversed: the cylinder air will discharge, and the piston spring will shut-o the liquid, followed im-
mediately by the atomizing and fan air.
For nozzles without integrated air control, an external control valve must be provided by the user for shung o the
atomizing and fan air supply. It is suggested by Spraying Systems Co. that a short ancipaon and following ming be
applied to the air supplies relave to the nozzle control valve in order to ensure complete atomizaon of the liquid.
Simultaneous actuaon may result in dripping or sping at the beginning or end of the spray cycle.
The manifolds have independent fan and atomizing air supply feeds, and these air pressures must be controlled via ex-
ternal regulators. For J-Style nozzles, the fan air supply is unused.
