PACKING
The pump is packed in a cardboard box. All components supplied as
standard are placed in the same package.
The weight of the equipment plus the packaging is ~27 Kg.
STORAGE
During transport and storage, make sure that temperatures between -15°C
and 40°C or 50°C for short periods not exceeding 24 hours are not
exceeded, which could damage the unit itself.
If the unit is to be stored, make sure it is stored in places with humidity
between 30% and 80%.
PLATE DATA
On the front plate, the equipment bears the manufacturer's identification
plate and the 2006/42/CE STANDARDS compliance plate, also represented
below.
The plate must not, under any circumstances, be removed, even if the
equipment is resold. For any communication with the manufacturer, always
quote the serial number (shown on the plate itself). On the body of the
pump there are some pictograms indicating safety warnings which must be
carefully observed by anyone preparing to use the painting unit. Failure to
comply with the provisions relieves the manufacturer from any damage or
injury to people or things that could derive from it and makes the operator
himself solely responsible towards the competent bodies. Replace the
nameplate and any removed, damaged or illegible stickers.

The equipment covered in this manual is a painting unit which allows you to
spray paint any type of material. Characterized by a remarkable
practicality, versatility and ease of use, the AST81 employs a pneumatically
operated high-capacity piston pump unit.
The airless spray system allows to considerably reduce the paint mist and
to guarantee a great transfer efficiency (over 80%). The system also makes
it possible to obtain perfect micro-atomization with considerable savings in
paint and a better surface finish.
The modularity of the equipment allows you to purchase only the pump unit
and then customize it with a large number of accessories.

TECHNICAL FEATURES
aircom.it .06
The painting unit uses a pneumatic system that can be fed at a
maximum pressure of 6.5 bar. Compressed air is used to obtain the
movement of the paint pumping piston and to obtain a high spraying
pressure with any type of paint and to obtain a high spraying pressure
with any type of paint without the use of air. All gaskets are of a special
type with high quality and high resistance; the valves are in stainless
steel.

The AST81 series painting units are designed for painting large surfaces and
for uses such as: painting on behalf of third parties, shipyards, large and
medium-sized carpentry shops, industrial body shops, mechanical
constructions in general. The products that can be supplied are: high solid
paints, normal paints, primers and glues. For the use of the equipment with
particular products, the approval of the manufacturer must be obtained, and
the adaptation of the technical characteristics of the unit for the processing
of such products.
Solvents such as trichloromethane and chloromethylene (dichloromethane)
can chemically react with the aluminum which makes up most of the pump,
leading to dangerous explosions. We advise you to always read the technical
data sheet of the product you intend to apply very carefully, avoiding the
use of materials that contain this type of solvent. Do not use regenerated
solvents (cleaning thinners), make sure they are free from acids (caused by
regeneration); these acids are responsible for the corrosion of the pistol.
