lar stainless steel manifold with 30 atomizing spray nozzles,
then launches millions of tiny droplets with a powerful fan
that produces 30,000 CFM (849.50 CMM) of air flow. Atom-
ized mist droplets of 50 to 200 microns in size are thrown
out in a 200 foot (60 meter) cone at an adjustable 0 to 50°
elevation angle, capturing airborne dust particles and drag-
ging them to the ground. Unlike industrial sprinklers used
for the same purpose, which can require hundreds of gallons
of water per minute, the DB-60 only uses about 23 GPM (87
LPM) to help avoid pooling or runoff.
Tier IV-compliant engines are designed to significantly
reduce emissions of particulate matter (PM) and oxides
of nitrogen (NOx) to near zero levels. Relative to previous
emissions standards, Tier IV-compliant engines reduce emis-
sions by over 95 percent for most agricultural and construc-
tion equipment and just over 86 percent for much larger
applications such as locomotives and marine vessels. The
Tier 4 emission standards are roughly similar to emission
reduction requirements for engines that power heavy-duty
trucks.

A touch screen panel for controlling the dust suppression
unit is encased in a NEMA 3R cabinet, allowing operators to
control oscillation, booster pump, fan and water. The cabi-
net is constructed for outdoor use, designed to provide pro-
tection against solid foreign objects (such as dirt), air (dust,
emissions), water (rain, sleet, snow) and ice formation. The
system provides valuable mobility and versatility in one of
the most popular and effective dust suppression designs on
the market, able to deliver up to 62,800 square feet (5,834
square meters) of coverage.
