Considerable care must be taken to manage finely divided
metal particles and dust. The appropriate NFPA or other
applicable standards should be followed when designing,
installing, operating, and maintaining dust collection
systems.
While the following
list is not all inclusive, it may help to know some of
the common design requirements. Some key requirements
for safe operation include:
-
The air velocity
in conveying pipes must be greater than 4,500 fpm.
- Downdraft or
backdraft tables should have a minimum of 150 fpm
air velocity at the surface.
-
An air curtain
should have a flow of at least 400 fpm.
-
The mass of
accumulated aluminum powder should not exceed 1
pound.
We offer both vacuum and filtration systems within our
equipment or as accessories. For more information on the
available devices please contact CenterLine.
Vacuums
CenterLine maintains a stock of custom explosion-rated
vacuums. These powerful vacuums are integrated into our
SSM-P3300-003 system but they can also be fitted with
casters for other portable applications. These machines
have a 1-1/2 HP motor operating at 220 V 60 Hz. They
also include a HEPA filter for the discharge air.
Wet Filtration Systems
We currently have 2,000 cfm and 5,000 cfm sizes. The
advantage of these systems is that they designed to trap
the waste in water so that there is no chance of
combustion. A supply of water and a drain must be
provided. The escaping moist air is commonly vented to
an area where it won’t cause a problem, such as outside
the plant or office. |
