⚙️ ASHRAE Spring Vibration Isolators (1"-3" Static Deflection, >95% Isolation)

HVAC Spring Vibration Isolator Calculator

Size housed and open-spring vibration isolators for rooftop chillers, cooling towers, and air handlers under ASHRAE Applications Chapter 48: calculate required static deflection (inches = 1.0" to 3.5" based on equipment operating RPM and floor slab span distance), achieve >95% vibration isolation efficiency, seismic snubber limits, and isolator profits.
