These roof exhausters are
used for the exhaust of relatively clean air from a wide range of commercial,
industrial and institutional buildings such a manufacturing and assembly plants,
office buildings, schools, hospitals, restaurants, athletic facilities and many
others.
The non overloading centrifugal
wheel with its higher static pressure capabilities makes this suitable for either
ducted or nonducted applications. It's roof mounting permits location near the
area to be ventilated, allowing short duct runs and more efficient operation.
The aluminum exterior provides
an attractive appearance. Belt drive results in lower operating RPM and sound
levels, making the Model DB well suited to applications where quiet opertion
is important. Belt drive also permits easy performance adjustment when needed
to balance the total ventilation system.
