Steel Housed Spring Isolator Mount
Acrefine AVI-S Steel Housed Spring Isolator Mount delivers premium vibration isolation performance with added protection from external forces. Unlike open or free-standing designs, this model encloses the spring within a rigid steel housing, providing structural stability and wind and seismic restraint capabilities. It effectively isolates vibration produced by reciprocating compressors, chillers, air handling units, and centrifugal fans. Thereby minimizing sources of noise and vibration that travel through the building structure.
The steel housing not only enhances durability but also ensures consistent deflection under varying load conditions. Moreover, the anti vibration assembly features powder-coated springs and zinc-plated fasteners that resist corrosion and extend service life. As a result, these vibration isolators are ideal for industrial or process equipment installations that demand maximum safety, structural restraint, and verified performance.
How to Select Deflection of Spring Vibration Isolators
Selecting the proper spring vibration isolator begins with identifying the correct deflection, typically 25 mm (1”) or 50 mm (2”). A higher deflection improves vibration isolation, particularly for mechanical equipment generating low frequency vibration. For heavy-duty or sensitive applications—especially those requiring seismic restraint—a steel-housed model is recommended to maintain both flexibility and stability. Our technical team can assist you in determining the right spring isolation mounts for your installation.
In addition, ensure that all spring mounts share identical operating heights to achieve uniform motion control. Mixing different models can cause uneven support and reduce performance. When correctly selected, the system remains balanced and secure, even in environments exposed to wind loads, seismic activity, or fluctuating equipment loads. As a result, your installation benefits from longer service life and superior operational reliability.
Acrefine Housed Spring Mounts for Seismic Restraint
Acrefine housed spring mounts are engineered to combine control with certified wind and seismic restraint protection. The enclosed steel casing shields the spring element from external impacts, ensuring steady performance even under building movement or vibration surges. Consequently, they deliver superior vibration isolation for chillers, cooling towers, compressors, and other heavy mechanical equipment. This design also helps maintain structural integrity and minimize the transmission of noise and vibration into surrounding areas.
In addition, every unit is factory tested and supplied with a test certificate confirming compliance with relevant seismic standards. The steel frame, together with high-strength fasteners, ensures long-term reliability and corrosion resistance. As a result, these spring mounts provide consistent vibration isolation, reduced maintenance, and verified safety. Ultimately, they represent the most robust solution for facilities that require seismic restraint and proven anti vibration performance in demanding environments.
