ADVANTAGES
Improved Durability
The newly optimized body design offers enhanced structural strength and durability, supported by a cylinder bore hardening process for long-lasting performance.
Quieter Operation
With its advanced cylinder head design, the piston significantly reduces exhaust pulses, ensuring lower noise levels during operation for a quieter working environment.
Greater Efficiency
The redesigned valve plate improves exhaust efficiency while enhancing shock resistance, enabling more stable and reliable performance in demanding conditions.
Expanded Operational Range
The upgraded motor boosts overall efficiency, allowing for increased overload capacity and a broader operating range to meet diverse application requirements.
Optimized Lubrication
The advanced bearing design enhances lubrication, minimizing the risk of shaft seizure and supporting smoother, more reliable operation over time.
Energy Efficiency
The improved piston structure reduces clearance volume, while the thinner piston rings lower friction loss, leading to greater energy savings and superior performance.
