NSA-14〜50
Features
Low-Depth Design Improves Workability
The NSA type features one of the shallowest installation depths in its class compared to equivalent models from other manufacturers.
This design helps reduce the risk of groundwater inflow or contact with bedrock, leading to approximately a 15% reduction in excavation volume.
Additionally, the simplified contact aeration structure ensures easier maintenance.
