Attention
•This product is designed for pneumatic devices.
The applicability of pneumatic equipment to the intended system
should be judged by the pneumatic system designer or the personnel
who determined specifications for such system.
•Since the operating conditions
for the products contained in this instruction are diversified, the
applicability of pneumatic equipment to the intended system should be
determined by the pneumatic system designer or the personnel who
determined specifications for such system. Before making a system,
the system designer should thoroughly examine all specifications for
such a system and also take into consideration the possibility of any
trouble with the equipment.
•The pneumatic equipment should only be handled by
persons who have sufficient knowledge and rich
experience
Improper handling of compressed air will result in danger. Assembling,
operation and maintenance of machinery using pneumatic equipment
should be performed by persons who have sufficient knowledge and
rich experience.
•Never operate machinery nor remove the equipment
until safety is assured.
Before checking or servicing machinery and equipment, be sure to
check that steps for prevention of dropping or runaway of the driven
component have been completely taken.
When removing the equipment, make sure that the above-mentioned
safety measures have been done beforehand.
Then turn off air supply and power to the system and purge
compressed air in the system.
When restarting machinery and equipment, check that proper prevention
of malfunction has been provided for and then restart carefully.
•When using the pneumatic equipment in the following
conditions or environments,
take the proper safety measures and consult Parker before hand.
•Conditions and environments (other than specified) and
outdoor use.
Applications to nuclear power equipment, railroads, aircraft, vehicles,
medical equipment, equipment connected with food and drink,
amusement facilities and safety devices such as emergency
interruption devices, clutch/brake circuits for a press and the likes.
Applications which require extreme safety and will also greatly affect
human and property.
1) After piping to Air Saver Unit and while the supply air is shut off, fully
close the ON time adjustment needle (clockwise rotation) and fully
loosen the OFF time adjustment needle (counter clockwise rotation).
Please use the dots for position indication of ON/OFF adjustment.
2) Turn on air to the supply port, air should pass to the output port
continuously.
3) Slowly loosen the ON time adjustment needle in CCW direction.
A pulsed air blow with short OFF time will start. It is suggested
to stop rotating the ON time adjustment needle at around 3 turns
(for ASV2000), 2 turns (for ASV5000), or 1.5 turns (for ASV13000
&15000) in CCW direction.
4) ASV2000&ASV5000:
Next, adjust the OFF time by slowly tightening the OFF time adjustment
needle in CW direction.
The OFF time of the pulsed air blow will get longer.
It is suggested to stop rotating the OFF time adjustment needle at
around 7 turns (for ASV2000 or 5 turns (for ASV5000).
This should result in about 50%
ON/OFF duty of pulsed air blow at 1.5Hz (ASV2000) or 2Hz(ASV5000).
ASV13000&15000:
Close OFF time adjustment needle fully by screwing the needle in CW
direction. Then, slowly loosen about 2 turns in CCW direction.
This should result in about 1Hz and 50% duty pulsed air blow.
5) Use the procedure of 4) as a starting point, and make the frequency
and duty adjustments required in your application by using the ON time
and OFF time adjustment needles.
6) Fix the adjustment position by tightening lock nuts on adjustment
screws.
Regarding repair and maintenance, please consult Parker.
* Adjust frequency of pulsed air to less than 5Hz (ASV2000&ASV5000),
0.1~1Hz (ASV13000&15000). If frequency of pulsed air is higher than
5 Hz (ASV2000&ASV5000), 1Hz (ASV13000&ASV15000),
operation of the pneumatic circuit (logistic element) may become
unstable.
•Be sure to cut air supply to Air Saver Unit when air blow is not used.
Blown air may come out even if the ON/OFF time adjustment needles
are fully tightened.
This unit is not designed to be an “OFF” valve.

Only for ASV13000 & 15000: Confirm “Continuous/Pulse
Needle” is fully opened before adjusting pulse cycles.
1) Do not supply air to the unit when adjusting the Continuous/Pulse
needle
2) The “Continuous/Pulse Needle” should be fully opened by loosing the
needle in CCW direction, and fix its position by a lock nut (Shipment
condition).
3) When the “Continuous/Pulse Needle” is fully closed, the main valve
position keeps the “ON” condition and does not create pulsed blow

a) Failure and countermeasure
Failure condition Cause Countermeasure
The unit cannot be operated. Pilot supply air might
be less than 3 bar
during operation.
Adjust pilot supply air
pressure properly.
Valve part is
contaminated
with dust or sludge.
1)Replace the product.
2)If air filter is not used,
use an air filter.
3)If problem is sludge,
use a coalescing filter.
Operating frequency is
getting slower.
Dust or high viscosity
oil is trapped in the
valve and it obstructs
the spool.
1)Replace the product.
2)If air filter is not used,
use an air filter
Contaminant is caught
inside of the pneumatic
circuit, and it blocks up
the flow
Replace the logic

Clean air mufflers or
replace them.

observed
From base gasket spool seal rings

Replace Air Saver Unit.
From base

Tightening torque for
mounting screws is not
enough to mount valve.
Tighten mounting
screws to appropriate
torque.
A) Before commissioning of piping
Thoroughly flush the inside of any pipes to remove chips, coolant,
dust, etc.
B) Air quality
2) If it is difficult to make filter drain management periodically, Parker
recommends setting up an air filter with automatic drain mechanism.
3) Be sure to take proper maintenance for a compressor. If sludge
produced in compressor oil enters pneumatic equipment,
it will cause operation failure of pneumatic equipment.
Parker recommends setting up a coalescing filter after a filter.
C) Pneumatic circuit
This unit is an external pilot operated valve. To avoid malfunctions due
to pressure drops, the external pil0t air supply pressure must be more
than 3 bar at all times. To avoid pressure drops during air blowing
process, set up relatively higher supply pressure and use tubes with
proper diameter.
D) Stopping the air blow
Be sure to cut air supply to Air Saver Unit when air blow
is not used.
Blown air may come out even if the ON/OFF time adjustment needles
are fully tightened.
E) Lubrication
This product does not require lubricated air.
Please do not lubricate it.
As a general rule, do not attempt maintenance or disassemble.
If it is absolutely necessary to do maintenance work, keep the following
points in mind.
1) Make sure that the actuators such as cylinders will not cause damage
if they move.
2) Cut off electricity.
3) Cut off pneumatic pressure and exhaust air in the line.
4) Clean up the surroundings of the valve.
•Any attempt to repair and/or disassembling of the product by the user
violates the warranty.
Parker does not take any responsibility for damage and injury caused
by it.
Note
Any request of after-service or maintenance parts, please contact our
distributors or Parker customer service. Keep this operation manual.
This operation manual would be changed without notice.
Please check the newest version.
Regarding repair and maintenance, please consult Parker.
This product is a pulse air generation unit with built-in soft seal (ASV5000),
and metal seal pneumatic valve (ASV2000, ASV13000 & ASV15000). This
product is mainly for reducing air consumption in air blowing applications.
Note 1) When ambient temperature of the unit goes below 5° C,
Complete dry air shall be supplied to prevent freezing.
Note 2) The featured Air Saver Units are external pilot operated unit.
Therefore, during air blow operation, external pilot pressure
should be more than 3 bar.
Please make sure to supply more than 3 bar for
external pilot air port at all time.
Please refer to our catalogue – Air Saver Unit.
