Oli Vibrators HF pneumatic immersion vibrator 50mm x 2mt

The Oli VHA50 is a high-frequency pneumatic immersion vibrator built for compacting concrete on lab tests through to heavy infrastructure pours. Poor compaction leaves air pockets and honeycombing in concrete, weak points that show up later as cracking or reduced strength. The VHA50 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 50mm steel head runs at 17,000 vibrations per minute with 5,627N of centrifugal force, 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 800 litres per minute of air supply, and runs continuously rated for -10°C to 60°C. Concreters use it on infrastructure pours, lab testing, and any site where compressed air is available but mains power isn’t.
