A
WORKING PRINCIPLE
MIRÓ LINER unit is defined line striper with diaphragm pump
An electric diaphragm pump is used for high pressure paint spraying
without air (known as “airless”).
This unit is powered by a petrol engine. An eccentric mounted on
the motor shaft drivers a piston which conveys oil to a diaphragm
on every stroke. The moving diaphragm draws the paint in through
the intake valve, compresses it and drives it out through the tiny
hole in the spray gun nozzle. An hydraulic valve on the hydraulic
case head allows setting and checking the pressure of the paint
product at the pump outlet. A second hydraulic safety valve to avoid
over-pressure, ensures total equipment reliability.
MIRÓ LINER is a small professional line striper that, thanks to
its reliable characteristics, grants a high quality performance when
used during marking and maintenance of urban roads. Being
an airless machine, the paint is atomised without air, therefore
without overspray, providing sharp high quality lines, with even
paint thickness. Thanks to the possibility of a quick colour change,
it allows a 30% increase of the production rate.
The equipment can be supplied, upon request, complete with a
glass beads dispenser.
The control zone offers the possibility of:
• Activating the spraying gun;
• Enabling or disabling the frontal steering wheel;
• Adjusting the operating pressure.
This type of equipment is capable of painting one line at a time
in a single color.
The line can be either solid or dotted, according to working re-
quirements.

MIRÓ LINER is ideal for small marking and maintenance jobs.
MIRÓ LINER allows for the marking and maintaining of all types
lines on highways, freeways, pedestrian crossings, parking lots
and squares, as well as every horizontal marking required by the
highway code.
Airless marking has numerous proven benefits with respect to
line-markers with pressurised tanks, which have been rendered
obsolete by airless-technology line markers.
Airless line-marking guarantees:
• Decreased Environmental Impact;
• Decreased drying time.
The paint dries quickly and the line is defined in a uniform manner
with a single coat. The airless function requires the use of filtered
paint which is specifically designed for airless application. This
means that the paint is homogeneous, of a smooth and uniform
consistency and will not form crusts, nor will it become gelatinous
or thick. With this airless line-marker, the paint adheres firmly to
all types of pavement, with optimal visibility, and is resistance to
wear caused both by traffic as well as atmospheric agents.
SOLID LINE BROKEN LINE
Use water or non-refractive solvent filtered paint
specifically designed for airless application.
This line-marker utilises non-premixed paints. This allows it to
achieve about 30 % more yield with respect to standard line-
markers. Every model is also an airless spray gun which can be
used in the construction/decoration sector together with washable
products, enamels, breathable paints and flooring resins.
A vast assortment of accessories is available to satisfy every
customer demand.
In the MIRÓ LINER model, the paint canister can be loaded di-
rectly upon the undercarriage or else poured into the non-stick, 50
L tank. In every case, cleaning, maintenance and colour change
operations are facilitated.
The line-marker is equipped with pivoting frontal wheel which even
increases the agility of the larger models.
