HDR100 Grey Vacuum Cylinder The HDR100 Grey Vacuum Cylinder is a replacement vacuum cylinder designed for compatible HDR100 lift and automatic cluster removal systems. Supplied without bracket, it is suitable where the existing mounting hardware remains serviceable or is being replaced separately, helping restore lift function without changing unnecessary parts. Vacuum cylinders are important for controlled movement within automated parlour equipment. If the cylinder becomes worn, slow to react, leaking or inconsistent, it can affect how smoothly the lift operates and may interrupt normal milking routines.
