HIGH-POWER VACUUM PUMP PERFORMANCE
The Dongfeng Vacuum Pump ensures reliable 20m³/h capacity with durable construction for consistent efficiency. Unlike budget machines with low-cost pumps, its robust design prevents performance degradation over time.
DONGFENG'S COPPER-CORE TRANSFORMERS
Dual pure-coil transformers ensure maximum conductivity + heat resistance for stable operation.vs Budget Aluminum Transformers Lower-cost machines use aluminum coils, increasing resistance and fatigue failure risk during continuous use.
| Copper wire transformer | What are the differences between copper and aluminum transformers | Aluminum wire transformer |
| strong | Electrical conductivity | weak |
| high | Fusing point | low |
| strong | Short-circuit resistance | weak |
| higher | Mechanical strength | lower |
| low | Electrical resistivity | Easy to increase |
| lesser | volume | larger |
INDUSTRIAL-GRADE SOLENOID VALVES
Dongfeng machines feature large solenoid valves for accelerated pumping, sustained efficiency, and stable sealing quality.
