Enclosed Spring Mount


Easyflex Enclosed Spring Type Vibration Isolators are designed primarily for building services applications where the control of low frequency vibration and noise emanating from mechanical plant is of paramount importance. The benefits of a combined rubber and steel housing for the spring have helped establish the EFESI mountings as industry standards accepted by specifiers, equipment manufacturers and mechanical services installers alike.


  • Neoprene rubber lower spring housing eliminates the possibility of metallic continuity and ensures excellent acoustic performance. Steel reinforced on EFESI range.
  • Full enclosed captive assembly protects the spring and controls transient motion.
  • All steel components are zinc plated.

Vibration isolators shall be free standing, unhoused, laterally stabile steel springs. Springs shall have a lateral stiffness greater than 1.0 times the rated vertical stiffness and shall be designed to provide a minimum 50% overload capacity.

Springs shall be assembled or welded between top and bottom load plates. The upper load plate shall be provided with steel leveling bolts, lock nut and washer for attachment to the supported equipment. The lower load plate shall incorporate a non-skid noise isolation pad and shall have provisions for bolting the isolator to the supporting structure, as required.

Springs shall be selected to provide operating static deflections shown on the Vibration Isolation Schedule or as otherwise indicated on the project documents. Springs shall be color coded or otherwise identified to indicate load capacity.

Spring Vibration Isolators for floor-mounted equipment shall be Model EFESI as manufactured by Kanwal Industrial Corporation (Easyflex).
