MISTRAL 451 BL D2

IGNITION SOURCE:
Element that triggers the explosion (spark, flame or temperature).

OXYGEN (AIR):
Fire needs oxygen to burn.

COMBUSTIBLE MATERIAL:
The fuel that will feed the explosion.

CONFINEMENT:
Closed and confined areas facilitate the concentration of
dust particles and gas.

DISPERSION:
Concentrated dust can easily turn into a cloud suspended
in the air, which increases the risks and damages caused
by an explosion.

Pneumatic conveyors is a system widely used in the food, agri-food, nutraceutical, pharmaceutical and chemical
industries. These systems allow the transfer, through closed/hermetic pipes, of bulk materials in powder or granule
form, from one starting point to another, eliminating the risk of contamination and dispersion of dusts.
The passage of a gaseous flow inside the pipes creates a (negative) pressure difference that allows the material
to move forward. The gas commonly used is air, but in industrial sectors such as the chemical and pharmaceutical
sectors, nitrogen is often required because, being inert, it is the ideal choice with potentially explosive materials.
The use of suitable conveyor systems for handling powders between the different processing machines can make all
the difference in the quality of the final product and in the safety of the working environment.
Pneumatic conveyors are used in many types of industries and their use can increase productivity by up to 30% and
the efficiency of the automatic machines on which they are installed, more than reduce the risk of explosion.

Delfin, through its technical department, and long experience in the design, manufacture and installation
of ATEX-compliant systems, develops and offers state-of-the-art solutions to meet the countless needs of industrial
processes.
All our centralized filtration systems are provided with dual filtration levels. Special design to grant containment of
continuous combustible dust cloud internally. Can be connected with a standard suction unit if installed in ordinary
location. Our system of filtration is designed to guarantee HEPA Efficiency downstream and to ensure a secondary
protection in case of failure of main filter.
We offer a wide range of power from 4 to 60HP, from 176 to 1353CFM, from 126 to 322inH2O

When it is necessary to vacuum in large work environments, with large distances to cover and utilizing several suction
points simultaneously, a centralized vacuum system represents the most effective solution. The system allows
the safe collection of material from different points of the production plant, including machinery integrated in the
production process. Such material can be easily gathered in a single point of the facility for easy disposal or recovery.
The vacuum systems therefore make it possible to improve productivity, operating conditions and safety standards.

For ordinary applications where workspace is not-classified as hazardous even if
dust is present in the process of production. In these cases, dust is usually well contained, and working areas are always carefully cleaned.
In these areas, equipment is not required to be ATEX certified. The ACD range is designed and certified Zone 20 internally compliant, granting higher safety requirements than an ordinary vacuum, even in non-classified areas.
Designed and certified not to generate ignition sources, and to safely collect and contain combustible dust, thus guaranteeing workplace and workers’ safety.
