Difference Between Open Type and Silent Type Generator
Selection Guide · 2026-10-09
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.
