Difference Between Open Type and Silent Type Generator

Noise level

• Open frame type: 80-85 dB(A) at 7 metres.
• Silent type: 70-75 dB(A) at 7 metres thanks to the sound-attenuated canopy.

Price and weight

• Open frame sets use less material, so the price is lower and the weight is lighter.
• Silent sets cost more but can be installed close to people.

Cooling and maintenance

• Open frame design has direct airflow, ideal for hot climates, and every service point is easy to reach.
• Silent canopy uses forced ventilation and removable side panels for maintenance.

Which one should you buy

• Choose open frame for construction sites, mining, farms and rental fleets.
• Choose silent type for hospitals, hotels, offices, shops in residential areas and telecom sites.
