A manufacturer of
woodcrafted items in Colchester, Connecticut planned to expand an existing
facility and had to select the proper dust collection system. They wanted a
positive pressure system to pick up sawdust and shavings from three saws,
shapers, several planers and sanders. Most of the material was pine sawdust with
some fines. The unit would be operated 60-70 hours per week.
Why was
this customer intrigued by the Griffin-Aire when they heard about it? The total
self-cleaning and lack of moving parts got their attention. That meant no
operational costs, no need to stock parts and no scheduled maintenance other
than to replace bags. The fact that Griffin designed the collector specifically
for the woodworking industry further convinced them. A conventional mechanical
or pulse jet collector would have been overkill for the job and a cyclone would
not have allowed the air to be recycled back into the building.
Griffin engineered this
unique and patented baghouse so it uses the kinetic energy in airborne waste
particles to blast collected dust cakes off specially coated filter bags. Then
gravity takes over. Operational costs are low since the only energy used is that
required to run the fan and airlock. It can run at higher air-to-cloth ratios
(15-20:1) than conventional baghouses and there is a constant pressure drop of
3"-4" w.g. The design could easily be adapted for other similar applications
where light density, coarse dust is collected.
For this particular
operation, the system was designed so the clean air was recycled back into the
building, while the dust was discharged through an airlock into a dumpster. In
addition to the other advantages of the Griffin-Aire, the owner was impressed
with its quiet operation and energy efficiency. The customer reported complete
satisfaction and 15 years later, the unit still runs six days a week. With its
expertise in meeting the demands of a specific industry, Griffin retains its
reputation for innovative design and application know-how. |
