gate, close the slide gate before servicing the dust
storage drum(s). The dust collector fan and compressed
air cleaning systems do not have to be turned off if the
hopper slide gate is closed prior to servicing storage
drums. Remember to open the slide gate when the dust
storage drum is replaced.
6.4 SERVICING THE COMPRESSED AIR
COMPONENTS
1. The compressed air system should be periodically
checked to ensure clean, dry, oil-free air is
delivered to the Supra-Blast dust collector. Check
the compressed air components and service as
recommended by the manufacturer.
2. Periodically check the dust collector air manifold
reservoir(s) for contaminants and drain any
condensed liquid from manifold reservoirs. It is
recommended that the customer install an automatic
air line drain valve at the lowest section of the
compressed air line piping to the dust collector
(refer to Figure 15).
3. With the compressed air supply turned on, check the
diaphragm valves, electronic solenoid valves and
interconnecting tubing between both devices for any
air leakage. Replace any components that are
defective or worn.
