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 (NBS90 PolySort)
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:
The NBS90 PolySort and SP pneumatic system does not require lubrication. Lubrication may
affect valve action 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 valves.
•
All airlines must be thoroughly blown out (of all debris) and the regulator must be set as
required before connecting air to the NBS.
•
NBS90 PolySort
diverters must not be operated above 55 PSI. Exceeding this may
damage unit.
