3.2 Functional description
The compressed air boosted Sprühboy 14 Airmix is
a closed compressed air system for the non-fogging
spraying of parting agents.
The Sprühboy 14 Airmix consists of the stainless
steel pressure vessel (1) and the compressed ai
r
boosted spraying system Airmix (2).
For the product from the stainless steel pressure
vessel to reach the compressed air boosted spraying
system Airmix, an agent pressure of between 2.5 and
6 bar is required inside the stainless steel pressure
vessel.
A
spraying pressure of between 0.5 and 2.0 bar must
be admitted to the spray gun's specially shaped
pressurised air nozzle to generate an even spray
pattern.
The agent or spraying pressure is adjusted via the
turning knob (1 or 2).
The manometer (3) indicates the agent pressure and
the manometer (4) indicates the spraying pressure.
The set pressure is read from the pointer on the
manometer scale (3 or 4). The scale is subdivided
from 0 to 10 bar.
The engagement depth of the agent quantity
adjusting screw (1) determines the amount of agent
sprayed by the spray gun.

3.3 General requirements on the
compressed-air source
The Sprühboy 14 Airmix requires an agent pressure
of at least 2.5 bar and at most 6 bar. The Sprühboy
14 Airmux may only be operated with food safe
compressed air.

It is imperative that you use only clean,
dry and food safe compressed air to
operate the Sprühboy. Oil lubricated
compressors, possibly with pressure
vessel with uncoated inside,
contaminate the compressed air and
consequently the agent to be sprayed.
If no filter unit (maintenance unit) to
clean the compressed air and also no ai
r
dryer is available behind the
compressor, oil and rust particles get
into the stainless steel pressure vessel
and clog the spray gun's agent nozzle.

If your present compressed-air source
does not meet the above requirements,
we recommend you use our three-stage
special filter unit.
The three-stage special filter unit consists of:
1. 1 x DV 1000. Prefilter with filter element and
automatic condensate discharge with float valve
and differential pressure manometer.
2. 1 x DF 1000. Superfine filter with filter element
and automatic condensate discharge with float
valve and differential pressure manometer. Fo
r
higher quality compressed air for pneumatic
control systems.
3. 1 x DA 1000. Activated-carbon filter with filte
r
element, stopper and closing plate. For highest
quality compressed air as inhaled air, e.g. in
luxury food processing.
4. 2 x Filter housing threaded joint. Fo
r
connection of filter units.
5. 1 x Assembly kit. For wall fastening of filte
r
units.
