Acrefine Spring Isolators

Open Spring Vibration Isolators

Acrefine AVI-B type vibration isolators are designed to minimize vibration and noise transmission from floor mounted equipment. The isolator has a load-carrying plate with rod for easy installation of equipment. AVI-B type has a bottom plate with two fixing holes to secure the spring isolator to the structure. Rubber pad is installed under the bottom plate.

Vibration isolation is achieved by free standing laterally-stable steel springs. Springs are designed with 50% overload capacity and the lateral spring stiffness is greater than the vertical stiffness to assure seismic stability. All springs are colour coded for easy identification.

Key Features
  • Load capacity up to 1555 kg (3429 lb) on standard range
  • Standard spring deflection of 25 mm (1″) or 50 mm (2″)
  • Powder coated for superior corrosion protection
  • Colour coded springs
  • Field interchangeable springs

Acrefine AVI-B type vibration isolators are a cost effective solution for minimizing vibration and noise from floor mounted mechanical equipment i.e. compressors, air handling equipments, centrifugal and axial fans, pumps, etc.

AVI-B type vibration isolators are available in 25 mm (1″) or 50 mm (2″) deflection as standard. The load range is from 7 kg (15 lb) to 1555 kg (3429 lb). For higher deflection or load capacities please contact us
