Ventilation duct
The Airflex Spectra-1000 ventilation ducts are used for air transfer in
ventilation and recuperation systems in residential, public and industrial
buildings.
The internal wall is entirely made of antibacterial and antifungal material,
which protects the ducts from colonisation by undesirable and dangerous
for people microorganisms. The material of which the ducts are made
was developed by Ingremio and is protected by patents. It was created in
cooperation with scientific centres in the course of a research project,
during which high effectiveness for different types of bacteria and fungi
was confirmed. The material contains silver, copper and other
microbiologically active compounds in the polymer matrix so that they do
not undergo migration, ionisation and elution. The virtual absence of
biologically active compounds migration from the polymer has been
confirmed in the laboratory tests that were performed in significantly
more aggressive environments compared to these of ventilation systems.
The substances used ensure in practice an indefinite bactericidal and
fungicidal effect and prevent the formation of defensive mechanisms by
bacteria and fungi regardless of air temperature and humidity. The
composition of the materials used is entirely safe for people, animals and
plants. Moreover, all materials used are approved for food contact.
The ducts are characterised by very high flexibility, so that they can be
freely shaped, bent at very small radii (according to the permissible
bending radii) and adapt to the installation conditions, without the need for
additional fasteners and fittings.
The duct structure ensures mechanical compression strength over 500 N,
which allows for their pouring over with structural concrete while
performing construction works.
The internal duct wall also has an antistatic effect, which reduces settling
and accumulation of dust in the ducts. The smooth internal surface
allows for high air flows with low-pressure losses, contributing to the low
energy consumption of the entire system. It also makes it easier to clean
the ducts if necessary. The double-wall structure of the ventilation ducts
with a properly profiled internal wall and closed air voids to a large extent
suppresses the entry of noise caused by air flowing inside and thermally
insulates.
The Airflex Spectra-1000 ventilation ducts are available in a wide range of
diameters, which allows for optimal selection to meet the requirements of
the ventilation system and construction conditions. The duct ends are
secured and sealed during the production process. The entire coil is
protected with foil, which prevents possible contamination during
transport and storage.
According to the Regulation of the Minister of Infrastructure on technical
conditions to be met by buildings and their location, the Airflex Spectra
type ventilation ducts should be installed in single-family buildings which
are not subject to requirements concerning reaction to fire.
