Quietech sound reduction makes MMD generators quiet enough to provide power for that all-important special event. PowerPro mobile generators are dependable and easy to operate, the right choice for all or your power needs.

Quiet acoustics that absorb vibration

  • Frame and housing are built with high-strength materials, and all doors and movable fixtures are engineered to minimize vibration

  • Sound Attenuated Enclosure is designed as an acoustical chamber optimized to reduce sound emissions. The enclosure interior is lined with a special vibration-absorbent, open-cell polymer material to cancel acoustic vibrations. This oil and soil resistant material is bonded to the cabinet walls with a resilient adhesive that enhances its performance

  • The unit's airflow has been engineered to provide proper cooling at an absolute minimum noise level

  • Direct-injection fuel delivery is quieter and easier to maintain. Oversized muffler results in a quiet exhaust

Compact, durable design

  • PowerPro machines are compact, yet offer unrestricted access to service components

  • Equipped with external service fluid drains, simplifies preventative maintenance service

  • Sound attenuated, sealed weather enclosures are powder-coated, and all hardware is stainless steel to maintain a fresh look for years. All cabinet doors lock with a common key

  • Off-white cabinet finish minimizes visibility impact in entertainment applications
