Technical points to confirm
- The product table labels power as 3680 kW and sealing power as 2000 kW. These entries appear to have a unit error; values are preserved as published and must be confirmed, not used for electrical sizing.
- Dimensions differ: 1238 × 1500 × 1545 mm in the model table versus 1270 × 1135 × 1575 mm in the range overview.
- Also listed as NEX-450M.
- The family graphic additionally lists 5.75 kW power, approximately 670 kg, 380 × 380 mm maximum box and a 63 m³/h Zhongde pump. These differ from some product/overview figures and need confirmation.
- Retains source component category wording; Schneider/Omron pneumatic labels may need supplier confirmation.
