| Shapes | |
| We
produce diffusers with circular, semi-circular and quadrantal cross
sections. Circular segments are manufactured on request. We can
also provide transitions between all shapes and dimensions as well
as extensions and arches. (more Technical

| Air distribution method | |
Air
is distributed from the fabric diffuser through openings with various
sizes. Combinations of sizes
and layout of the openings together with various output velocities provide
numerous variations.
The scope of options begins with distribution of air at low speeds and
continues up to targeted air
supply for long distances. |
|
There
are distinguished small holes with diameters 0.4 mm that are called
microperforation are designed
for dispersion of air. In case of targeted air supply there are used
series of holes with diameters 4mm
or more that are called perforation. It is necessary to take into account
effects of temperature differences
when calculating flow velocity in a certain distance. |

We
often face a requirement of cooling and heating using one system.
However, the way of distribution of air must be completely different
for both regimes to provide effective heating and draught-free
cooling. This contradictory requirements can be resolved using
a membrane diffuser that is divided horizontally in the centre
using thin impermeable textile - membrane. This membrane can cover
(and thus put out of operation) the upper or lower longitudinal
half of the diffuser. The upper part is designed to diffuse air,
the lower part is designed to direct high-speed air flow downwards.
The delivery also includes a special flap with a servomotor that
allows switching over between both regimes of air distribution. (more  Membrane

| Microperforation | |
The
required permeability of the textile can be achieved using
modification of a minimum permeable textile using micro-perforation
(punching of a very high amount of very small holes). The holes
can be distributed randomly of their size can be determined
as necessary. This also helps to direct the air flow. Permeability
of the textile eliminates creation of condensate on its surface.
Holes prolong maintenance intervals and service life of the
diffusers. Microperforation

| Installation | |
We
use specially developed assembly materials that are included
in the delivery. In principle, there are two ways of installation
- suspension on stranded wires or mounting into profiles. Detailed
technical information is available on request.
