From open steel spring mounts and rubber-in-shear isolators to flexible duct connectors and acoustic hangers, we supply complete vibration control for commercial plants and industrial machinery.
Free-standing and housed steel springs for heavy chillers, AHUs, and pumps.
Rubber-in-shear pads and mountings for fans, compressors, and small units.
Spring and rubber combined hangers for suspended pipework and duct infrastructure.
Canvas and neoprene duct connectors to prevent transmission of mechanical vibration.
Where standard weights and load footprints vary, we calculate correct deflections and supply custom-rated spring assemblies,inertia bases, and seismic restraint systems to protect structural integrity.
All vibration isolation components supplied by DM O'Shea conform to stringent mechanical engineering thresholds to maximize structural protection and attenuate low-frequency noise.
| Mounting Type | Static Deflection Range | Typical Equipment Applications | Construction & Material Specs |
|---|---|---|---|
| Rubber Pads / Blocks | 2 mm to 5 mm (Low Deflection) | Small cabinet fans, lightweight compressors, chillers | Neoprene / ribbed natural rubber compounds |
| Rubber-in-Shear Mounts | 6 mm to 15 mm | Air handling units, pumps, reciprocating compressors | Bonded steel plates with high-grade elastomeric core |
| Open Steel Springs | 25 mm to 75 mm (High Deflection) | Large centrifugal chillers, cooling towers, heavy fans | Powder-coated steel coils with non-skid acoustic pads |
| Housed Spring Isolators | 25 mm to 50 mm (Restrained) | Rooftop equipment subject to wind load and seismic forces | Cast iron / steel housing with built-in limit stops |
| Acoustic Spring Hangers | 25 mm to 50 mm | Suspended fan coil units, inline duct fans, heavy piping | Combination steel spring and rubber element in steel bracket |
