Air Supply and Line/Connector Requirements
Generally speaking there is very little maintenance required for your Air-Operated PowerHandler
provided the units are set-up correctly at the outset. Below details the most important items to check in
regard to initial set-up and trouble-shooting, particularly in respect to air supply.
For optimal
performance of a PowerHandler, sufficient air supply is essential. The following criteria should be
achieved to ensure sufficient air-flow and performance.
Recommended air pressure and volume
Supplied air pressure should be 6-7 bar (85-100psi) for all models & series of PowerHandler. Above 7 bar
(100 psi) air pressure can damage the vanes of the air motor. The required air volume depends on the
model as larger motors consume more air. See below:
Air Volume: (Litres/min)

/min)
(44 cfm)
Model
A25S, A30S
A40S,
A60S,
T40S
1250 lpm
1500 lpm
(53 cfm)
In most cases, standard “factory supply air” will accommodate this recommended pressure and flow rate,
however special attention should be paid to air lines and connectors (see below).
Air lines and connectors should not limit air flow / volume
More than 90% of all performance problems users experience with air-operated PowerHandlers are a result
of undersized airlines or connectors.
Additionally, the length of the air line inversely affects air flow and therefore performance. The shorter the air line
the better the performance and a maximum length of 15m (45ft) is recommended for diameters listed in the table
below. If an air line longer than 20m is required, the air lines and connectors should be upsized further. Too
small of a diameter air line (relative to its length) will result in significantly reduced power – evident by both
slower running speeds and less torque.
Please note minimum required internal dimensions of the air lines, connectors and fittings per the table
below:
Model
Min. Int. Diameter: Air Line

, A60S
12mm (½”)
13-15mm (½”-5/8”)
Connector
12mm (½”)
13-15mm (½”-5/8”)
For safety, an overhead “curly cord” style airline is recommended with the PowerHandler located in its
desired working area. This makes use of the device easier while presenting less of a trip hazard than
having the airlines running across the floor (see photo on next page)
OPTION: SWIVELING AIR LINE CONNECTOR.
PowerHandling offers an inexpensive connector that is sized at
12mm (½”) and swivels 360º for improved maneuverability -
whether the airline is overhead or running down to the floor.
