🪓 ASHRAE Table 48 (Open/Housed Steel Springs 1.0"-2.0" Deflection, fn <3.5 Hz)

HVAC Spring Vibration Isolator Calculator

Size open and housed steel spring vibration isolators (Mason Industries / Kinetics) for chillers, AHUs, and centrifugal pumps under ASHRAE Chapter 48: calculate static spring deflection (1.0" to 2.0" rated deflection yielding low natural frequency f_n < 3.5 Hz providing >95% vibration isolation efficiency across sensitive structural spans), and MEP contracting profits.
