In spite of intensive racking one’s brain, the correct
solution sometimes cannot be found: How can a crossing of
the ventilation tubes be avoided without excessively long
loops? Besides, even with many meters of tubes it may be
impossible to avoid a crossing. Moreover it is possible
that due to the existing soundproofing regulations and sound
sensibilities placing tubes one over the other is no longer
With the new crossing for tubes, this problem has been solved
in a very simple way. The collection and distribution box
is opened on all four sides. In transverse direction the
exhaust air is conducted in an uninterrupted tube, whereas
in longitudinal direction the conduct for the inlet air
is interrupted so that the air can find its way around the
exhaust air tube to the continuation of the inlet air tube.
An interesting question of course was, whether the aerodynamic
resistance would not be too large and therefore cause a
disproportionate pressure loss. Measurements made by HSLU
in Lucerne however show that the pressure loss is minimal
and therefore negligible.
Collection and distribution box MINI
Very often the question has arisen: Do we really need a
complete collection and distribution box for a small separate
apartment in a one-family house on in one or two room flats?
With the collection and distribution box MINI RoomAir offers
a simple and economical solution.
Based upon the very well-known air inlet/outlet box, this
unit is supplied with four openings (on the rear there is
an additional possibility) and equipped with a round fixture
of 125 mm.
What makes this product very special is that customers contacted
us with this idea and suggested that we modify the very
versatile box in such a way that it could be used as collection
and distribution box. We are keen to see what further ideas
our customers will have!
By the way: The HSLU in Lucerne has tested this distribution
box and confirmed that our „MINI“ has an extremely
small pressure loss!
The number of users of the air distribution system RoomAir
is steadily increasing both in Switzerland and abroad. Now
also the newly founded Dimplex - Airsystems (Glenn Dimplex
Group) is working with RoomAir.
