30 Series – Acoustic Spring Hanger
The 30 hanger series can be fitted with a range of springs to suit acoustic and weight requirements. Spring hangers are used to isolate against low frequency noise from sources such as footfalls and mechanical vibration.
The 30 series spring hangers incorporate a large lower hole to allow the hanger rod to swing through a 30° degree arc from side to side before contacting the cup bushing and short circuiting the spring. This is significantly more than comparable spring hangers on the market and reduces the risk of isolation failure due to hanger misalignment.
When load is applied to these hangers, the springs will deflect, and the attachments will lower. If minimal movement is required, pre-compressed spring hangers (PC30) can be used instead. The springs are compressed before installation, so they do not deflect until a pre-set percentage of the total load is applied, at which point they release and function identically to standard 30 series hangers. Care must be taken to ensure the pre-compression washers release once the installation is complete to ensure there is no vibration short-circuit.
