5.6 Attaching the Air Connections
Source air may be supplied externally by a compressor or other source of clean, dry air with a
maximum pressure of 6.9 bar (100 psi). The source air should be attached to the port on the
control box labeled “Air - Inlet” (see Figure 5-11). The supply air hose and fitting are supplied by
the customer and should be rated properly for the air pressure of the supply. The air inlet port on
the control box is a 1/4 inch NPT female thread. The fitting can be installed with PTFE tape or
pipe sealant. To not choke the air flow rate to the mast, a 3/8 inch or 8 mm inner diameter hose is
recommended.
9 meters (30 feet) of 3/8 inch inner diameter air hose is supplied with the mast system along with
two 1/4 inch NPT hose barb fittings. Install one hose barb fitting to the control box port labeled
“Air - to Mast” (see Figure 5-11) and the other hose barb fitting to the cross fixture at the base of
the mast (see Figure 5-12). PTFE tape or thread sealant can be used on the hose barb threads.
Route the air hose and connect both ends to the fittings. The hose can be cut to the desired
length.
When nesting the mast, exhaust air will exit the control box through the port labeled “Air -
Exhaust” (see Figure 5-10). The exhaust air hose and fitting are supplied by the customer. The
port is a female 1/4 inch NPT. It is recommended to use a larger inner diameter air hose and
fitting than the supply port to not restrict the exhaust flow rate (slows mast retraction rate) and
also to prevent someone from accidentally connecting the air supply to the exhaust port. The
