Features

• Powder-proof pneumatic motor technology
  Featuring a uniquely designed pneumatic turbine motor, this technology completely isolates foreign matter (such as powder) during both coating operations and color change cleaning. This prevents powder contamination that could otherwise cause the rotary bell to jam. Currently, it is the only electrostatic powder rotary bell gun with this patented technology.

• Two innovative bell cup technologies
  The uniquely engineered rotary bell cup prevents short-term powder build-up on the cup head that can lead to surface defects such as “powder spots” or “pinholes.” Cleaning and color changes can be performed without disassembly, significantly enhancing production efficiency. This is the only electrostatic powder rotary bell gun with such technology, ensuring long-term coating without powder shedding.

• Closed-loop automatic speed control
  All rotary bells operate at consistent speeds controlled by the main unit. The LCD automatically adjusts and displays the actual rotary speed in real time, eliminating manual intervention. Consistent rotary speed produces uniform “powder clouds,” resulting in smoother and more even coatings.

• High transfer efficiency & enhanced safety
  Equipped with ultra-high electrostatic voltage (110 kV) and ultra-low current (approx. 30 μA under normal operation, max ≤ 100 μA). With three patented electrostatic control technologies, the system automatically reduces high voltage and current when the rotary bell approaches grounded workpieces. This minimizes reverse ionization, improves transfer efficiency, prevents sparking, and enhances operational safety.

• High-speed dynamic balancing technology
  Every rotary bell undergoes high-speed balancing during production, greatly extending service life. This process is unique to this electrostatic powder rotary bell gun.

• Streamlined design
  The streamlined gun body minimizes powder accumulation on surfaces, improving reliability and reducing maintenance needs.

• Durable pneumatic motor
  Precisely engineered with special German-imported materials, the pneumatic motor is highly durable and efficient. At 8,000 rpm, air consumption is only 15–20 L/min, making it the lowest air consumption pneumatic motor among powder rotary bells available today.
