Low Noise Acoustic Damping Rubber Shock Mount Silent Block with 50 Shore A Hardness for Blower Fan Noise Control

This low noise acoustic damping rubber shock mount silent block is designed for blower fans, where a lightly loaded but fast spinning unit sends a steady hum through ducts, hangers and frames. The rubber shock mount silent block places a 50 Shore A natural rubber element between the fan foot and the mounting surface, breaking the structure-borne noise path so the noise reaching the room is reduced. As an acoustic damping mount it is a neat way to quiet a blower without rebuilding the whole assembly.

Because the rubber is set at 50 Shore A hardness, the mount is soft enough to isolate the fine, high frequency vibration of a blower yet firm enough to keep the fan steady. The natural rubber resists aging, oil and weather, so the blower fan vibration isolator keeps working in dusty workshops and humid plant rooms. The silent block fixing is simple and captive, which means the acoustic damping mount stays put under continuous rotation and needs almost no maintenance.

Facility teams fit a low noise rubber shock mount whenever a blower or fan adds unwanted hum to a workspace. This acoustic damping mount pairs well with flexible duct connectors and hanger isolators for a complete noise control approach. With a documented 50 Shore A hardness and a compact silent block body, it offers a straightforward, dependable way to cut blower fan noise and vibration.

A complete noise control job usually combines a low noise rubber shock mount with flexible connectors and, where the ducts are overhead, hanger isolators. Used together, these parts keep blower vibration out of the frame and the ductwork so the fan runs quietly without expensive enclosure work. Because the acoustic damping mount is compact and low cost, it is easy to standardise across a whole ventilation system.
