Source Air Connection
Select the best position along the conveyor to connect the source air from a drop line. Ideally, the
regulator should be centrally located along the sorter and should not be more than 80' from the furthest
diverter/transfer or drive.
Attach the filter/regulator assembly to the bottom flange of the side frame using the mounting bracket
supplied with the kit.
The source airline that distributes air to the diverters/transfers should be 1/2" hose that is rated to
handle a pulsating 60psi line pressure. TGW Systems part number 89000572 TUBING, URETHANE
1/2 OD is available for this purpose.
Cut into the supply line along the sorter bed and install the source airline tee fitting TGW Systems part
number 89000640. Connect the source air line between this fitting and the filter/regulator output.
The hose size at each diverter/transfer is 3/8 OD and the source airline can be tapped at each location
using TGW Systems part number 89000640 1/2” tee and 1/2” x 3/8” tube reducer fitting TGW Systems
part number 1155149.
Low Pressure Air Switch
The installation of an air pressure switch in the NBS air supply circuit, to detect a drop in air pressure
below required levels, is recommended. If pressure drops below approximately 40 PSI, the conveyor
system should shut off.
It is recommended that this air switch be located either at the furthest end of the source air line away
from the regulator or at the pneumatic belt take-up located in or near the drive bed at the discharge end
of the sorter.
•
Do not use a lubricator. When replacing filter/regulator bowl, lightly lubricate seal with
mineral oil. Do not use synthetic oils such as esters or silicones. DO NOT get oil inside
filter/regulator bowl.
•
The function of the low pressure air switch is to protect the drive pulley and the NBS
narrow belts from being damaged from slipping under load in the event of an air
pressure disruption. Loss of air pressure may also cause diverter / transfer jams.
