The Masterflow
®
Heat Blower
is a heavy-duty, industrial-
quality heat blower suitable for
continuous duty applications.
It produces a high volume of
hot air for demanding indus-
trial applications. The
adjustable stand features a
keyhole slot for easy equip-
ment mounting and allows the
nozzle capability of rotating
90° (horizontal to vertical).
Your Masterflow
®

with a thermal fuse which will
protect the element from over-
heating or burn out due to
a nozzle blockage or motor
failure.
Heat blowers are a source

tures, regardless of your
specific application,
extreme care and caution
should be observed when
using this product.
Therefore, we recommend
that you pay particular
attention to the safety
instructions which we have
