IPV Series Air Hammers
• One impact wave caused by one shot
• High strength aluminum structure
• Impact force and interval timing can be set based on requirement
• Magnetic hammer stores magnetic strength to increase the piston’s
impact power
Series IPV Air Hammer (single impact model) focuses on a limited
target. Other equipment of the target is minimally affected by it. The air
hammer’s impact won’t separate water out of humid mixtures. It is often
applied onto a pipe or clean elbow in a tank filled with humidity or low
specific gravity material.
HOW IT OPERATES
The IPV series air hammer contains a powerful magnet inside the
hammer. The hammer and magnet are tightly closed before activation.
However, as the inlet air pressure gets higher than the force, this
tightens the hammer and magnet. The hammer and magnet will
separate and cause more strength for impact power. The spring will
bring the hammer back to the initial position automatically after the
impact. By doing this, the air pressure will be released and the strength
of the air pressure will be delivered to the target impact container. It will
help to smooth the flow and prevent accumulation inside the container.

INSTALLATION
Vibration force transmits more efficiently in a conical hopper tank as
opposed to a rectangular hopper. It is recommended that you install two
vibrators in rectangular hoppers.
1. Vibrator force can be transmitted more efficiently by using “U” shape
steel supports. It can help materials run smoother in the tank or pipe. It
also reduces tank damage accidents.
2. To avoid tank wall amplitude caused by the vibrator moving in a left or
right direction, use “U” shape steel.
3. Reinforced board is required between “U” shape steel and a thin tank
wall.
4. To increase vibration fields in a big hopper tank, criss-cross “U” shape
steel.
Attention: Vibration has to be fixed by a high tension bolt, washer, and
spring washer. Connect with a security cable if the vibrator is installed
onto a hopper.
Vibration Force Calculation
Taking the accumulated situation into consideration, the appropriate
vibrator will give 0.2~0.5 G accelerated vibration onto the target object.
F= 0.2-0.4 GW F: Vibration force (N)
G: Acceleration of gravity
W: Material weight (KG)
Material Weight Calculation
Generally speaking, the hopper portion of the tank should be taken into
consideration.
MAINTENANCE
Upon final installation of the Series IPV Air Hammer, no routine
maintenance is required. A periodic check of the system calibration is
recommended. The Series IPV is not field serviceable and should be
returned if repair is needed (field repair should not be attempted and may
void warranty). Be sure to include a brief description of the problem plus
any relevant application notes. Contact customer service to receive a
return good authorization number before shipping.
NOTES:
Various tanks are based on application requirement. Customers choose
appropriate vibrator types to meet with various applicant demand (tank
shape, material, applied material, etc). Suitable vibrators will not only
prevent obstruction problems but won’t damage the tank walls.
Large amplitude and low frequency piston types fit in granule with low
specific gravity applied material. It is recommended to use multiple
vibrators in serious clog situations or large tank surroundings. According
to various clog situations, required vibrations and suitable install
positions (usually 1/2 L or 1/3 L) are shown below.
