Air Vibrator Piston Vibrator (Open type)
Product Overview
The pneumatic piston vibrator has long been used for concrete formwork vibration in tunnel construction due to their rugged design and suitability for explosion-proof environments.
They have also been used for many years in industrial applications, particularly for preventing blockages in weighing hoppers at precast concrete plants and ready-mixed concrete batching plants.
Key Features
Rugged Construction for Harsh Environments
Built with a rugged ductile iron housing and a simple air-supply connection, these pneumatic piston vibrators are designed to withstand harsh operating conditions.
Their valve-free construction ensures reliable performance in demanding construction sites and ready-mix concrete plants.
Reduce the Number of Vibrators with a Dedicated Mounting Holder
Pneumatic piston vibrators are designed for concrete placement systems where the vibrators are repositioned as the pouring operation progresses.
Dedicated mounting holders allow quick relocation, while direct mounting is also possible to suit different site conditions.
* Optional holder is available.
Simple Design and Reliable Operation
With a simple vibration mechanism and few moving parts, the vibrator offers exceptional reliability and long service life. Backed by decades of proven performance, it ensures dependable operation in the field.
Operates with Air Supply Only
To ensure reliable operation, use a solenoid valve or air-operated valve for rapid air supply. The lubricator should be installed within 5 m of the vibrator.
Excessively long air lines may reduce lubricant delivery and cause malfunction due to insufficient lubrication.
Adjustable Vibration Force with Air Pressure Control
By adjusting the air pressure with a pressure regulator, the vibration force can be finely tuned to suit the application.
This flexibility allows optimum operation for a wide range of mounting conditions, equipment shapes, and weights.
Provision for Safety Wire Installation
PSB and PLB models feature a safety wire attachment point.
* Safety wire installation is recommended. (Optional accessory)
