Optimal Sound reduction
The M-SQ 22.5 comes standard with a robust sound-shield with corrosion proof metal plating and heavy insulation material for optimal sound reduction. The sound shield is equipped with easy entry to all sides of the generator and offers access to all maintenance related components from one-side.
Units can also be delivered without a sound-shield. Ask for our open units with or without sound-shield.
