Piston vibrators with piston rod

VTL -  series (VTL-155 up to VTL-1105)

Steel housing

In contrast to the FAL series, the housing of the VTL types is made of steel. (Except type VTL-155, this has a plastic housing with aluminum end plate and steel piston / pls. see picture below). The relation between weights to force of this units makes the applications of material conveyances particularly efficient.

The piston vibrators the VTL series are characterized by a free-flying piston. This means the piston exits with a rod from the vibrator housing. If the mutually vibrating machines / device groups are fixed on the one hand to the bottom of the vibrator housing and on the other hand to the piston rod, the piston stroke generates a particularly large amplitude with linear oscillation.

The vibration frequency can be controlled via air pressure. The VTL series piston vibrators produce linear vibrations with a large vibration frequency and a wide amplitude range. The VTL vibrators are not knockers, what means the piston does not strike the bottom. The piston will be decelerated by an arising air cushion – either at the bottom or at the top side – and will be accelerated in the opposite direction.  The centrifugal force / time curve is therefore almost sinusoidal without peaks by knocks. This attribute makes this types perfect for any cases of conveying material.
Explosion-proof, compact design and low noise level while operating characterize these vibrators. The VTL piston vibrators are easy to install and designed for a long lifetime with minimal maintenance requirements.

The vibrators are also available in accordance to  ATEX    II 2 G & D Zone 1, 2, 21, 22.
