Quietshield® Silencers
Breakthrough Silencer Design
At Univeral, we have a history of developing innovative sound and emission control devices. Our innovation tradition was established with Nelson and Nelson-Burgess' know-how throughout the years. Wtih the new Quietshield® Silencer, we did not disappoint our tradition.
There are design components to consider when selecting a silencer — level of attenuation, silencer size, and backpressure. The rule of thumb is "You can have two, but not three." To gain in one area, another needs to suffer.
The Quietshield® breaks the rule of thumb by allowing all three! Universal took the best of both traditional designs, Nelson and Nelson-Burgess, and combined them into a breakthrough silencer design. It incorporates reactive and absorptive silencer technologies to provide a smaller, less restrictive and higher performing silencer.
| Feature | Benefit |
|---|---|
| 35% Better Acoustic Performance | Reduces chance of noise complaints Utilize a lesser grade of silencer for cost savings |
| 50% Less Backpressure | Engines operate more efficiently Less wear and tear on engine components Allows retrofit opportunities with emission and control devices |
| 20-25% Smaller Size | Easier to fit into tight enclosed packages and equipment rooms Easier to install = less labor cost |
