Suggested requirements for NBS sorter and diverts
Every conveyor system is unique, with its own specific requirements. Therefore, the following is a
general guide.
MAIN FEEDER
: Air velocity through the main feeder piping can be kept smooth with lower losses using
large diameter pipe with minimum bends and restrictions. Standard weight black pipe or copper is
suitable for plumbing the compressed air overhead to all points of use.
AIR DROPS:
TGW Systems recommends using 3/4" pipe on air drops for high flow and low pressure
loss. The drop is terminated with a drain at the bottom. A tee located prior to the drain branches off to
the conveyor. This branch line must contain a lockout/shutoff. A shutoff must also be located in the drop
before the branch tee. OSHA Rule 29, CFR1910.147 requires energy sources (air drops) be turned off
and capable of being locked or labeled with a warning tag.
Note:
NBS pneumatic systems does not require lubrication. Lubrication may affect the valving
operation and cause sluggish or erratic operation.
Important:
If your air compressor uses synthetic oil, a coalescing filter plus a regular filter of 5 micron is
required. Synthetic oils will shrink the seals in pneumatic devices and valving.
•
All air lines must be thoroughly blown out (of all debris) and the regulator must be set
as required before connecting air to the NBS.
