Negator Spring Applications – Ruskin and Air Balance

This application is different from all the others. The springs are attached to the damper

blades and instead of a fusible link, there is a fusible rod that connects the blades to the

motor. Replacement rods are available, but the springs are typically broken or missing.

If they are intact then a kit is available from Ruskin. See below.

If the springs are not intact, then the rod can be replaced with ones made by a

machine shop. A Belimo BAE 165 US sensor can be installed. This upgrades the

damper to modern standards. Call for information.

INSTRUCTION SHEET

Ruskin makes a kit with a shaft

adaptor, hold down, and Belimo

FSLF120 actuator.

Replacement fusible rods are also

available in two lengths.

Where the springs are defective

solid rods, a BAE 165 US sensor,

and rewiring are necessary.
