switch. A timer controls the duration of the shake cycle and a flasher controls the
cylinder movement by powering the solenoid valve.
3.6.4 Cartridge Dust Collector
These Dust Collectors can operate continuously without Blower shutdown.
Electronically timed pulses of compressed air clean the dust from the cartridges
without interfering with normal airflow. Refer to the manufacturer’s manual for
complete information.
3.6.5 Dust Collector Efficiency
Dust Collector efficiency may not be stated as an absolute value since it will vary
depending on:
a.
Dust loading of inlet air
b.
Micron size distribution of dust carried by inlet air
c.
Amount of dust cake on filters (frequency of filter cleaning)
Emissions from Empire Dust Collectors in good condition will normally be within the
OSHA limit for “nuisance dust”. The OSHA limit is 5 milligrams of dust per cubic
meter of air (.002l85 grains per cubic foot). This emission rate is equal to .0042
pounds of dust per 1000 pounds of air at standard temperature and pressure. To
determine the actual emission rate, an air sample from the blast operation must be
analyzed.
Dust Collector efficiencies are stated to show the normal range which might be
expected and are not a guarantee of performance.
If dust contains any toxic substances, secondary filtration of discharge air from the
Blower may be required. Consult Empire if dust to be filtered is classified as other
than “nuisance dust”.
