Piston vibrator EPV

Features

Piston vibrator EPV series is a pneumatic vibrator that produces a stable vibration by vertical operation of piston. This is used mainly for prevention of blockage or filling of powder in hopper, tank, or piping chute, and for vibrating source of table vibrator, vibration conveying machine, and vibrating sorting machine. *Use a normally closed three-way valve for control of activation and stop.

Piston vibrator operating principle

1.　Uses AG43 (normally closed type) solenoid valve.Air is supplied to the piston vibrator by energizing.
2.　Intake air A pushes the piston down to the spring side, and then when piston reache the exhaust postion, inside air is exhasued.
At the same time, intake air B is performed.
3.　Air entered from Intake B pushes piston up to upward.
When piston reaches the exsaust positon, inside air is exhasut and intakes A is performed at the same time.

Simple Installation

The piston vibrator can be installed with one bolt, and can be installed to a place where vibration is required.
Also, it can be installed in any direction of 360 degrees.

Stepless regulation of frequency by changing air pressure.

The frequency and vibration force can be changed by adjusting the air pressure.

Excellent durability

The internal piston part is subjected to wear resistance treatment by EXEN's original special technology.
Durability is improved by using stainless steel for the lower cover.

Since it can be operated in oil-free (completely dry air is strictly prohibited)

Since it can be operated in oil-free (completely dry air is strictly prohibited), it can be used in a wide range of fields from the general industrial machinery field to the food, pharmaceutical, and chemical industries.

(Caution 1) Oil-free refers to general service air that contains almost no oil.
(Caution 2) Use with oil-free air that contains almost no oil or water may shorten the product life.　Avoid using in complete dry air.

Low operating noise and easy to work environment

Since the internal silencer system is adopted, the exhaust noise is quite low.

Economical with low air consumption

Eco-friendly design also saves energy.

Application to vibration feeder and vibration packer.

Can also be used in watery sites

It is not waterproof because it has an exhaust port, but the main body excluding the exhaust silencer is waterproof.
For use in watery sites such as food factories, extend the exhaust silencer and install it downward.

Manual operation panel

An easy-to-operate manual pneumatic vibrator control panel.It can be operated immediately with only the vibrator air tube and compressed air.
