Series APV Piston Vibrators that are air cushioned help to provide low
noise character. This makes it suitable for quiet area application. It is a
good solution to prevent clogs on tank walls and material delivery prob-
lems. Piston impact types also can help to get rid of rust and material
accumulated inside pipes. Direct impact on a tank with low specific grav-
ity and high moisture material inside will help prevent material build-up
and pipe clog or rust.
WORKING PRINCIPLE APV-C
There are air-breathing tubes located in both ends of the cylinder.
Compressed air pushes the piston from one side to the other side.
Vibration power arises as the piston moves back and forth in the body.
Air cushion at both ends produced by the to-and-fro compression will
keep the piston from striking the body. Therefore, the piston will not pro-
duce much noise.
WORKING PRINCIPLE APV-I
There are air-breathing tubes located in both sides of the cylinder.
Compressed air pushes the piston away from one side and to the other
side. Vibration arises when the piston moves back and forth in the body.
Air cushion at the top end is produced by the to-and-fro compression.
This will keep the piston from striking onto the body top. The piston will
strike directly on the bottom side of the body to produce a strong impact.

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.
