Thrust Restraints

Easyflex Model EFTR Thrust Restraints are used to counteract the discharge force created by fans during operation. EFTR Thrust Restraints are used in pairs and best utilized when located on the centerline of the discharge outlet of the fan, bridging the flexible duct connector.

Easyflex Model EFTR Thrust Restraints consist of high deflection, large diameter, laterally stable steel coil springs assembled into a threaded rod and bracket assembly. The coil spring have a lateral spring stiff-ness greater than 1.0 times the rated vertical stiffness to assure coil minimum of 50% overload deflection capability to solid. The coil springs are epoxy powder coated for corrosion protection. EFTR Thrust Restraints feature molded neoprene end load plate assemblies. EFTR Thrust Restraints include threaded adjustment rod with hardware, fan and ductwork mounting bracket angles, bracket back-up plates, and all attachment hardware.
