Proper size selection is extremely important in choosing any air
hose in order to prevent “starvation” of the air tool, and to insure
maximum torque and tool speed. Starved tools don’t produce!
Steps in size selection:
1. Determine air flow rate and pressure required by following air-
tool manufacturers recommendations.
2. Refer to “Air Flow Characteristics” Graphs, shown at right.
Find air flow requirement in standard cubic feet per minute
(SCFM) on vertical line to left of graph. Now follow horizontal
line on same graph to determine total extended length of hose
required. Follow vertical line above hose length to intersection
with the horizontal air flow SCFM line.
3. Note pressure drop above curve nearest to intersection of
SCFM and hose length lines. Pressure drop, subtracted from
line pressure, equals “available pressure” at the selected
SCFM flow rate and hose length.
4. If “available pressure” is below the tool manufacturers’
recommendations, refer to chart for successively larger hose
sizes until an acceptable “available pressure” is found. Choose
this size Fast-Stor® Air Hose for your application.
5. Refer to “working pressure vs. temperature” chart to be sure
your application falls within the working range of Fast-Stor®
Air Hose.
