Use M5 screws to secure the SJ-H Series in the
installation location.
■ Removing the air booster
1
Remove the air booster side support B.
2
Remove the straight air booster (wide angle booster)
through the groove on the static elimination bar guide rail.
The straight air booster (wide angle booster) can
be removed as a single unit by using a narrow,
slotted screwdriver or similar small tool to unlock
the lock.
3
Remove the air booster side support A.
■ Supplying air
As shown in the diagram below, install the joint to the air supply opening in order to supply air.
• Be sure to use a joint tightening torque of 1.2 N •m (12 kgf•cm) or less. Otherwise
an accident or malfunction may result.
• Be sure to supply air from both sides (2 locations).
• Please contact the nearest KEYENCE office when opening and closing the air duct.
Recommended joint
We recommend using the tube fitting (tube diameter
φ10 mm) joint manufactured by Nihon Pisco.
• Use a joint with a tube diameter of φ10 mm for the air booster.
• When supplying air to multiple units at the same time, supply air to each air booster. If an attempt is
made to supply air to multiple SJ-H Series unit from one air supply source, sufficient air supply may not
be obtained.

Static Elimination Ability Chart
■ Static elimination area and static elimination time
The following examples show the relationship between the time required for static elimination on the
target and the operating distance from the target to the static elimination bar.

Straight air booster
●
Wide angle booster
■ Relationship between air pressure and flow according to static elimination bar length
The relationship between the supplied air flow and the air pressure changes depending on the static elimina-
tion bar length.
Refer to the typical examples and select an air supply device (compressor) that will provide sufficient air flow.

Wide angle booster
■ Relationship between static elimination speed and operating distance depend-
ing on air pressure
The relationship between the static elimination speed and the static elimination bar operating dis-
tance is different depending on the air pressure.
Refer to the typical examples and adjust the air pressure.
