QS Super Silenced Series -
trailer mounted portable diesel powered traffic system
|
|
 |
The QS Super Silenced is a further development of our popular standard trailer. This integrated system enables our diesel powered trailer to operate at an amazingly low noise, with sound levels similar to an electric desk fan.
|
|
With greater emphasis on noise pollution, the QS provides the answer, representing an 87% noise reduction over a standard AC1 diesel engine. Independently measured sound levels of 50 dBA at 7 metres, the QS is ideal for use in residential and other built up areas.
