Shrouds
The shroud is the heavy duty stainless steel
housing attached to the bottom of the thru-shaft
housing that encases the spray bar keeping water
and debris contained for optimal vacuum extrac-
tion. The vacuum hose is connected to the top of
the shroud by cam lock connectors. Shrouds are
available in various sizes to accommodate the
spray bar selected.
Wear Brush
A wear brush clamped to each blasting head
shroud provides a partial seal between the blast-
ing head and pavement. The wear brush regulates
vacuum air flow into the shroud and reduces the
amount of debris and water exiting the blasting
head during waterblasting operations. The wear
brush is an important safety feature of the blast-
ing head system. It must be adjusted as it wears
and replaced as necessary. The brush assembly
should be adjusted so the brushes are always
making light contact with the pavement.
To adjust the wear brush, lower the blasting heads
to the ground and note the gap between the wear
brush and the pavement. Loosen the brush clamp
on the blasting head shroud, then slide the wear
brush enough to eliminate the gap. Tighten the
clamp and recheck. Readjust if necessary.
Refer to the Maintenance section of this manual for
additional information on adjusting and replacing
the wear brush.
