Abstract
Ventilation ducts and accessories have been shown to get dirty during
the storage and installation at the building site. Most important factor that
makes the inner duct surfaces dirty is the metal dust that is accumulated
while side grinder is used to cut the ducts. The aim of the study was to
develop a clean installation method for ventilation ducts, by the use of which
the new national ventilation cleanliness class can be achieved. The
laboratory tests and field experiments showed that the side grinder widely
used nowadays in Finland can be replaced with shears. Shears do not produce
metal sheet dust, do not sparkle and are not as noisy as the side grinder.
Also, the speed of work and work safety are good with the shears. The
operating characteristics of the shears were appraised good and the assembly
workers were satisfied with the new method.
