10.5EFSH - Spring Hangers

EFSH Spring Hangers consist of freestanding. laterally stable steel springs in series with a molded elastomeric element assembled into a stamped and welded hanger bracket. The hanger brackets and the springs are powder-coated. Spring vibration isolation hangers are designed to provide high-efficiency isolation from structure-borne vibration and noise. Springs are color-coded and in compliance with ASHRAE guidelines; springs are designed with a horizontal stiffness of at least 100% of the vertical stiffness to ensure stability. This is achieved through high spring diameter to operating height ratios - 0.85 to 1.0 (as against the minimum of 0.80 required by ASHRAE).
