Hence, isolation of low frequencies requires further effort compared to the isolation of high frequencies. Considering the transmissibility curves and results of the vibration survey conducted at the site, it is decided that low frequency isolation elements are more suitable for the vibration isolation. Rubber pads, steel springs and pneumatic springs were considered as alternatives within the scope of this study. There are several factors that must be taken account when selecting the proper isolators such as operating temperature, unit cost, creep of the isolator material, life time and maintenance costs. Steel spring type isolators have long life span and can effectively absorb the low frequencies, however significant amplification occurs in the vicinity of resonance frequencies due to low damping capacity.
