SKU: 6190-VHA80
The Oli VHA80 is a high-frequency pneumatic immersion vibrator built for compacting concrete on the largest pours a site handles. Poor compaction leaves air pockets and honeycombing in concrete, weak points that show up later as cracking or reduced strength. The VHA80 runs on compressed air rather than electricity, so it works inside wet concrete without overheating and keeps running through conditions that would stop an electric vibrator. Its 80mm steel head runs at 11,000 vibrations per minute with 15,829N of centrifugal force, the highest in the VHA range, fed through a 2-metre SBR rubber hose that's reinforced with internal textile and carries no moving parts, cutting vibration transfer to the operator's hands and arms. It needs 6 bar of working pressure and 1,300 litres per minute of air supply, and runs continuously rated for -10°C to 60°C. Concreters use it on mass pours and heavy civil structures where a large head compacts deep sections fast.

About Oli HF Pneumatic Immersion Vibrator
It's used to compact concrete on mass pours and heavy civil structures, running on compressed air rather than electricity.
It has an 80mm steel head, the largest in the VHA range, running at 11,000 vibrations per minute.
No. It's a pneumatic vibrator that runs on compressed air, so it works without mains power and doesn't overheat inside wet concrete.
It needs 6 bar of working pressure and 1,300 litres per minute of air consumption, the highest air demand in the VHA range.
It produces 15,829N of centrifugal force, the highest in the VHA range.
It's rated for continuous duty from -10°C to +60°C.
It weighs 14.2kg.
