Cup Spring Mounts for Vibration Isolation

Easyflex EFCUS Type Spring Isolators are engineered to deliver superior vibration isolation for a wide range of HVAC and industrial applications. These isolators are highly effective in controlling both high and low frequency vibrations generated by equipment such as reciprocating compressors, refrigeration systems, pumps, air handling units, centrifugal and axial fans, and internal combustion engines.

Designed as free-standing units, these spring isolators offer exceptional lateral stability without requiring additional restraints. One of their key design advantages is the optimized ratio between the coil’s outer diameter and its operating height. With a minimum ratio of 0.80—and in many cases close to a 1:1 ratio—these isolators ensure maximum stability during operation, even under varying load conditions.

The springs are engineered with low operating stress levels, which significantly enhances their lifespan and ensures long-term, reliable performance. Unlike traditional designs, the EFCUS Type Spring Isolators feature a weldless construction. The spring coils are not welded to steel plates; instead, they are securely assembled using elastomeric cups and steel base plates. This design not only improves durability but also allows greater flexibility when replacing or interchanging springs.

Installation is made simple and efficient with the inclusion of a built-in leveling device. This feature allows for precise adjustment during setup, ensuring proper alignment and optimal performance of the supported equipment. Additionally, each unit includes a bottom cup with a bolt hole for secure attachment to the structure.

For added convenience during installation and maintenance, the springs are color-coded. This makes it easy for technicians to quickly identify the correct isolator type and load capacity, reducing errors and saving time on-site.

With a load capacity ranging from 30 kg to 1250 kg, Easyflex EFCUS Type Spring Isolators are versatile enough to support a wide variety of equipment sizes and applications. Their combination of strength, stability, and intelligent design makes them an ideal choice for professionals seeking reliable vibration isolation solutions.
