Pneumatic linear vibrators for bulk material flow
In industries dealing with bulk materials, achieving consistent flow can be challenging, especially with hygroscopic substances, coarse particle sizes, or powders tending to granulate. Traditional methods often fail to prevent issues like bridging and rat-holing, leading to operational inefficiencies.

Facilitates material flow and reduces noise
The Cushioned Pneumatic Linear Vibrators K-series from WAMGROUP are designed to generate linear vibration via an internal floating piston rather than surface impact. This mechanism is particularly effective for bulk materials that stick, such as hygroscopic substances or powders prone to granulation. With a noise level capped at 80 dB(A) and a clean design, these vibrators are ideal for indoor applications demanding low noise and cleanliness. The K-series vibrators are also ATEX EX II 2DG cT(x) compliant, making them suitable for explosive environments. Available in four sizes, they feature anodized aluminum construction and operate at pressures between 2 to 6 bar (29 to 87 PSI). Installation and retrofitting are straightforward, offering flexibility in various processing environments.
