BLASTING ROOMS
Sandblasting is the most efficient
technology for cleaning and other
surface treatments. It is also a hard
and environmentally unfriendly work.
Till nowadays blast work was mainly
done in open spaces, thus polluting the
environment with dust and old paint
residues containing heavy metals and
poisonous chemicals. It is also a rather
very loud procedure. Meantimes strong
environment protection regulations
oblige everybody to work according to
environment protection standards and
to particular safety regulations
regarding blast work.
Our know-how and more than 45 years of experience can assist you in solving any of your
problems with pollution or with personal protection equipment.
The sole law-conformant solution for the cleaning of large objects is the blasting in closed systems
with recycling and filtration – ECOLOGICAL BLAST ROOMS.

Our PNEUMOFLEX recovery system was developed for light abrasive materials and is used
exclusively for the recovery and the recycling of glass beads, ceramic beads, plastic granulates and
exceptionally (occasionally) electro-corindon of very fine grain size or similar light abrasives used for
blasting.
For the recovery of heavier abrasives (cast steel shot or grit, corindon or slag abrasives of big grain
sizes) from the blastroom floor we recommend our scraper recovery system type GUMIFLEX.
Scraping of abrasives on the floor can be partial or total, the drive of the system is usually electric but
can also be pneumatic. The scraper elements on the floor automatically feed an elevator for vertical
transport of the abrasive, which is then continuously cleaned in a separator and deposited for a new
blast cycle in a silo above the pressure blast pot. Depending on the size of the blast room, there can
be installed one or two pressure blast pots.
The choice of the abrasive material depends on type and material of the surface to be blasted, on the
required end result (quality) and on procedures following the blast operation (painting, coating,
galvanization, finishing to look like INOX,etc.)
Usually such choice of abrasives is done by our technicians, based on their experience, or blasting
tests are done first, either on site or in our laboratory, using various materials and abrasives.
SCRAPER RECOVERY OF ABRASIVES – GUMIFLEX, Producer: FerroECOBlast
In blast rooms are usually installed a few scraper elements, covered by steel grids of different load
capacities.
Scrapers are installed inside technological pit and each element has its own drive, pneumatic or
electric. The function of the scraper elements is automatically controlled by the electric control panel
that also signals stoppages or other malfunctions of scrapers, elevator and other electric
components.
DRAWING:
Designing and manufacturing these
equipments by our own, we can grant
you a 3 years warranty, and we also
guarantee for a continuous operation of
the system, for a perfect cleaning of the
abrasive recovered, and for long lifetime
of the system.
With different types of scrapers and
inventions we can meet all customer’s
requirements.
Thanks to long time
experiences and numerous
executed projects all round
Europe, we can adjust to
various sizes of blast rooms.
Basic pit is shallow and in some
cases it is possible to install on
flat (?level?) surface without
basic pit.
Every manufactured part is
carefully assembled in our
production line and tested under
heavy conditions.
Quality is at the end guaranteed
with three year warranty.
ABRASIVES RECYCLING SYSTEM
Following the scraper elements, this is the
second most important system of a blast room.
It is assembled with the elevator that lifts the
abrasive to a certain height where it is
separated and cleaned, staying in closed
system. After that there is mechanical cleaner
that removes dust from abrasive by blowing
through air curtain and with built in separation
system keeps 100% quality abrasive in
circulation.
BLAST SYSTEM
That is the most important component of the
whole assembly.
We produce and supply these in different sizes
and capacities. A lot of blast room details
depend on the choice of the blast system. i.e.
the size of the silo in which the abrasive is
stored above the pressure pot.
Further details about blast systems and
personal protection equipment can be found in
our special brochures.

Direction of airflow is important and so
is the right choice of type of filtering
system.
Usually, dry filtering systems with filter
cartridges and automatic “pulse-jet”
cartridge cleaning are used. For better
working conditions and save of energy
in winter we recommend to recycle a
part of the clean air from the filter back
into the blast room, the recycling rate
being adjustable.
The type of the filter unit depends on
the blast room size, the type of abrasive
used, and the anticipated time of
continuous blasting.
For each specific case the filter unit size
and performance has to be calculated
separately and cannot be based on
previously executed projects.
CONTROL BOX
The electric control panel in an industrial, dustproof version can be of standalone type or fixed on
the wall with top or bottom cable inlet and outlet. It contains all safety, control and signaling
switches necessary to operate all components of the blast equipment. The working state of all
components can be displayed on a scheme with light indicators on the control panel front side,
showing the function or the stoppage and any other malfunction for component individually.
There are rules and restrictions regarding working conditions and safety equipment in blast
rooms.
For blast rooms like for any other closed working space, special standards apply, defining the
lightening necessary to operate, the emergency lights and other signals to be installed. That is
why we recommend to have the whole project, including the electro installation be carried out
by a specialized, professional staff!
It is important that workers, even under hardest
working conditions, have everything under
control. Being protected with leather suits and
ventilated protection helmets, their mobility is
restricted and every safety regulations therefore
have to be strictly followed.
- Working with pressure blast systems without
remote control is forbidden and can have major
consequences
- The working areas must always be clean
and floor covered with grids, so that the worker
does not slip
- Ventilation and suction, together with the
blastroom lighting must be intensive enough to
leave perfect visibility onto the surface to be
blasted at any time.
Some pictures of blastrooms, which were built in
accordance to all today existing standards and
regulations in Western Europe. All built-in
components have the CE-certificate.
WORKING AND AUXILIARY AREA
That blastroom is divided by PVC door curtain
in a working and an auxiliary area. The floor of
the basic working area is completely covered
with grids, underneath are the scraper
elements, and the walls are fitted with rubber
protection. In this area most of the blast work
is done. In case of bigger and longer parts the
auxiliary area is also used, being mainly
intended for preparation work before blasting.
Also separated from the working area, by a
wall in sandwich construction with integrated
service door, is – on the opposite side – the
machinery room, where are installed the
elevator with separator, the blast system with
silo, and the drive units for all longitudinal
scraper elements. It might also be used for the
storage of abrasives, spares, and the personal
protection equipments of the operators, as well
as for service purposes.
