Intercooler and aftercooler
The cooler is arranged vertically, which greatly reduces the noise from the fan,motor and rotor.

Two-stage spiral tooth rotor
• No need to vent the pressure vessel, lower energy consumption compared to single-stage compression system
• Ability to quickly reach low energy consumption in no-load state

Soundproof enclosure
• No need for a separate compressor room
• Available only on WorkPlace Air System™ models

Induction motors
• Flange mounting for precise placement
• IP55 Class F motors
• Dry motor coupling requires no lubrication, eliminating maintenance requirements

Air filter
• SAE fine particle removal 99.5%; SAE coarse particle removal 99.9%
• Long life, high reliability, long maintenance interval
• Combined air filter and muffler to ensure sound insulation

Integrated VSD inverter
• No unloading operation, no oil tank emptying loss, higher energy efficiency
• Operate in a narrow pressure band, reducing the working pressure of the entire system
