INDUTAIR
The INDUTAIR system consists in the construction of circular perforated modules that integrate the function of duct for the conveyance of air and traditional air diffusion elements. The inductive effect triggered by the calibrated holes made in the metal pipelines, characterize the type of diffusion of the system. The strong momentum generated by the air micro turbulences on the holes, trigger a strong recall of air in the immediate vicinity of the duct, significantly amplifying the amount of ambient air in motion, allowing a strong mixing and thus a significant reduction of stratification phenomena.

Operation
The inductive effect triggered by the reamed holes in the me-
tal ducts is the main feature of this system’s diffusion type.
The high inductive effect generated by the micro-turbulences
of the air coming from the holes, causes a strong suction of
air near the duct (Induction Ratio: 10 to 30), significantly in-
creasing the quantity of room air in mo-
tion with low Delta T and low speed; this
allows thorough mixing and therefore a
considerable reduction in layering and
the elimination of any areas of air sta-
gnation.
The smaller diameter holes generate the
strong induction effect while the larger
ones drive the mixed air in the required
direction and at the required speed.
The speed of the out-going air, in the
initial part of the duct, has a tangential
component due to the speed in the pipe,
so it pushes the room air towards the
end part of the duct and then sucks it
back in the initial part, thereby genera-
ting longitudinal circulation in the room
as well as perpendicular circulation.

Application
INDUTAIR ducts can be applied in a number of situations and
are suitable for a wide range of civil and industrial solutions.
Inductive diffusion: an application that optimizes the control of
the temperature of treated throughout the entire space, with
checks on the comfort conditions in the living area (residual
speed).
Air displacement diffusion: mainly used for diffusion via falling
cold air and normally designed to control the temperature and
residual speed in a space equal to the surface of the treated
room considering the height of the living zone only (about 2
metres).
Air curtain: normally used to generate a barrier with a concen-
trated air launch on a zone that affects a space which has
different temperature characteristics, without any control over
the comfort in the living space.
Air blast: normally used to achieve a thermic load in a specific
direction through direct thermic action, with a pre-defined final
speed.

They also have many advantages over traditional systems, in
both economic and technical terms:
• Reduced installation costs
• Air return ducts system is highly simplified.
• System and energy saving
• Quick installation
• Visible system
• Low levels of layering
• Effective air mixing and uniformity
• No stagnation zones
• Architects appreciate it highly as a
furnishing element
