Spring & Neoprene Mounts

Neoprene Mounts & Spring

The HVAC Spring & Neoprene Mounts category is where you go when standard rubber pads are not enough and structure-borne noise has to be brought under control. Fans, pumps, chillers and air handlers can transmit low-frequency vibration through steel, concrete and framing into occupied areas, causing complaints about humming ceilings, rattling lights and “thumping” equipment. Properly sized spring and neoprene mounts isolate that vibration at the source, protecting both the building and the equipment.

Here you’ll find open spring mounts, housed spring mounts, neoprene mounts, combination spring–neoprene mounts, ceiling hanger isolators and inertia base components sized for air handlers, fans, pumps, rooftops, split-system air handlers and mechanical-room equipment. Springs are selected for specific deflection ranges and frequencies, while neoprene elements provide additional damping and stability. Used correctly, these mounts help you meet sound, vibration and comfort targets in multi-story, mixed-use and noise-sensitive projects.

• Open and housed spring mounts for fans, pumps and large air handlers.
• Neoprene mounts for light- to medium-duty HVAC equipment.
• Spring–neoprene combo mounts for maximum isolation and control.
• Ceiling hanger isolators for suspended fan coils and ducted units.
• Inertia base mount components for high-mass, low-vibration systems.

When selecting HVAC spring and neoprene mounts, always confirm equipment operating weight, center of gravity, RPM/frequency, number of mounting points, required deflection and structural conditions. Rooftop and mezzanine installations may need higher deflection to avoid amplifying building movement, while mechanical rooms above quiet spaces often rely on spring mounts paired with housekeeping pads or inertia bases. Correctly engineered mounts protect piping, ductwork, electrical connections and internal components from long-term stress and misalignment.

Pro tip: For best results, treat the equipment, piping and ductwork as one vibration system. Spring or neoprene mounts do their job only if you also allow for flexible connections and avoid rigidly tying isolated equipment back into the building structure.
