DESCRIPTION
They are blown air burners, with gas/air mixing in
the combustion head. They are fit for operating on
high pressure or in depression furnaces accor-
ding to the working range. The long blast tube ver-
sion is sliding on flange to meet any possible
application. They offer a high flame stability along
with total safety and high efficiency: they are pro-
vided with a regulator/stabiliser which keeps the
gas/air ratio steady even in the presence of ordi-
nary disturbing causes of the combustion process
such as tension variations (which entail altera-
tions of the motor revolution number), residues on
the fan, etc.
DELIVERY
The burner is delivered fully assembled and packed. It should be unpacked only at the time of
installation on the boiler to prevent any accidental damage.
