Findeva DAR-4 is a heavy-duty pneumatic roller vibrator developed for applications requiring high centrifugal force, including concrete compaction and bulk-material flow. The model provides continuously variable vibration performance across the published 2, 4 and 6 bar operating points.
The DAR-4 uses a rotating cast-steel roller running in highly flexible steel guides. The housing is made from extruded aluminium alloy and reinforced with shock-resistant bronze covers.
At 2, 4 and 6 bar the DAR-4 operates at 18.0, 22.5 and 25.0 ×10³ min⁻¹ and generates 2360, 4610 and 6690 N centrifugal force.
Published air consumption is 120, 250 and 360 l/min at 2, 4 and 6 bar.
