VHA – Internal pneumatic vibrators

VHA is a reliable vibration system designed to provide high operating frequency with high working efficiency under safe conditions. For this reason it is ideal for every type of compaction: from lab tests to heavy infrastructure projects.
There are no moving parts inside the hose, this means less vibration on the hands and arms of the operator and an extended service life.
As a pneumatic vibrator, VHA doesn’t need electricity and can even work out of concrete without overheating. This means no work interruptions even in severe conditions.
Ease-of-use and maintenance-free make the VHA the perfect solution for compacting concrete when electricity is not available.
