PNEUMATIC DUST TRANSFER SYSTEM (option)
Assemble the hoppers to the bottom of the modular filtering units. Follow
these easy steps:
1. The main dust collector blower(s) should be installed first.
2. Use a forklift to hold the hoppers underneath the modular filtering units.
3. Install the six (6) bolts which will squeeze the bottom of the modular
filters to the top of the modular hoppers.
4. Make sure that the six (6) bolts are tighten properly and seal to the
filtration unit, achieved.
5. Installed each additional modular hopper the same way.
6. Install the two closing plates at each end of the modular hoppers.
Install the two blowers of the transfer system and the transfer piping as per
drawing 0482-BVD-00000 of appendix 3. Minimize as much as possible the
use of 90 degrees elbows and flexible ducting, in the piping.
When the system is in operation, verify that your container doesn't leak. If it
does, a slide gate must be added at the inlet of the pull fan. It must be slightly
closed to compensate the fact that the container leaks.
