Shaker type dust collector
13
13.4 Anchors
All sections of the collector should be firmly anchored to a cement slab in order to prevent tipping
of the unit should an explosion occur or due to extreme winds.
13.5 Interior installation
When a dust collector is installed inside of a building, the collector should be installed within 10
feet of an exterior wall and be connected to a vent duct connected to the exterior of the building.
This vent duct system should possess the same pressure capabilities of the collector.
If the filtered air coming from the collector is recycled back into the building, certain precautions
should be taken in order to exhaust the air outside of the building in the event a filter inside the
collector should fail in its performance or other performance deficiency. A secondary filtration
system should be considered to protect staff or personnel within the building. Bursts of air
exhausted out of the collector or of the explosion vent should be directed out of the way of
pedestrian walkways, parking lots, offices or any other area where people could have access.
13.6 Processes creating sparks
If dusts or collected matter is present in the collector or in the equipment connected to the
collector, no activity that could create sparks such as welding should take place until the system
has been shut down and thoroughly cleaned. If similar operations should be performed in the area
of the filter envelope, such filter should be removed and stored in a dry area.
14 MAINTENANCE
WARNING!
Refer to the Safety measures section before proceeding with
the inspection or maintenance of the dust collector.
A scheduled preventive maintenance program will reduce downtime situations and increase
lifetime of the unit. Charts shown in this chapter refer to maintenance and procedures related
in solving malfunction. Timers and delays may be modified with conclusive experimenting of the
system on a particular application.
14.1 Replacing the filter envelope
The lifetime of the filter envelope is directly linked to its resistance to the dust filtered and does not
necessarily require a regular filter replacement. However, if the filter envelope is torn or punctured,
it needs to be replaced as soon as as possible.
