FSL SPRING ISOLATOR

Spring isolation units type FSL comprise a group of heavy duty helical springs contained within robust steel platforms.

Applications
FSL springs can be used either under a foundation or mounted directly under machinery or building structures.

Construction
Fabricated steel platforms used with helical springs to BS 1726-1:2002. As standard the springs are painted black and the platforms are painted to the customer’s colour choice.

Properties
Low frequency vibration isolation for sensitive machinery.

FSL Steel Springs can be used either on their own on in tandem with FV dampers. Where the system in likely to go through resonance and excessive movement is a concern it is recommended that FV dampers are used in conjunction with FSL springs. FSL steel springs can be employed in a variety of combinations and support arrangements, Farrat will design isolation systems to meet a customers specific technical requirements. To assist our customers in the smooth running of every project Farrat provide construction drawings and installation instructions with all FSL springs supplied.
