AIR CONSUMPTION
Air consumption in cubic feet per minute
(cfm) for the AMPT-12 can be calculated as
follows:
cfm = (a) x (b) x (0.20)
a = Number of straps applied per minute.
b = Number of seconds motor is on per
strap during tensioning, from start to
deceleration to stall including stall
time while making joint when.
0.20 = AMPT-12 efficiency ratio.
Example Calculation:
Peak strapping load: 4 straps/min. so a = 4
Air motor run time: 5 sec./strap, so b = 5
AMPT-12 efficiency ratio is 0.20
(a)x(b)x(0.20)
6 6 6 6
4x5x0.20 = 4 cubic ft/min.
Air pressure is assumed to be 90 psig (6.2
Bar) with recommended size and length of air
hose. Volume of air is at room temperature
and sea level pressure, or so-called "free air"
conditions. For more detailed information
about air supply systems refer to Signode
manual Part No. 186038.
COLD WEATHER OPERATION
If a tool does not operate satisfactorily in
freezing temperatures, certain steps can
correct the problem. The following steps can
be taken to improve cold weather operation
of the tool:
a. An air line dryer adjacent to the
compressor.
b. Use lubricant recommended by Signode.
Signode has tested the use of anti-
freezes, none work well in air tools; the
tool will gum up when anti-freezes are
introduced and will not function properly.
The best lubricant for freezing weather is
the 1 to 1 oil and kerosene combination.
c. If possible, run the air supply line to a
indoor located Filter-Regulator-
Lubricator or relocate the F-L-R to a
warmer operating area.
