Powder Coating System for Manual Coating Equipment, GC21F with Hopper
Powder Hopper Capacity 50L
Output Voltage 100kV
Input Pressure 5.5-6bar
Maximum Powder Output 520g/min
Developed as a flagship model for high-end export markets and high-precision part coating, the powder coating system for manual coating equipment, GC21F with hopper integrates an advanced control chip and intelligent sensing algorithms.
Equipped with a modular heavy-duty trolley and a 50l powder hopper, the GC21F is especially suitable for applications that require highly consistent coating results, such as premium aluminum curtain wall profiles and export-oriented home appliance production lines.
Digital Core Control:
The GC21 controller uses a high-performance 32-bit processor and supports up to 20 programmable coating programs. Each program can store voltage, current, powder output, and atomizing air pressure settings, allowing complex coating processes to be recalled with one touch and helping operators achieve consistent coating quality more easily.
CANBus Connectivity:
With an industrial-grade CANBus communication interface, the system can be linked with external workpiece recognition systems or reciprocators, providing strong support for intelligent production upgrades and digital factory integration.
High Transfer Efficiency:
The MG20 high-performance manual spray gun features optimized airflow design to improve first-pass powder transfer efficiency. Combined with multi-angle nozzles, it can reach complex corners, edges, and deep recessed areas more effectively.
Applications
Variety, Small-Batch Coating:
Suitable for customized architectural hardware, small-batch mechanical brackets, and trial coating of experimental samples.
Touch-Up and Precision Coating for Complex Parts:
Ideal for the inner areas of construction machinery cabins, complex grille structures, and electrical cabinets with deep cavities.
Frequent Color Change Operations:
Suitable for aluminum profile sampling, multi-color sports equipment, and decorative metal furniture.

System Components
This system mainly includes the GC21 main control unit, MG20 manual spray gun, mobile trolley, 50L powder hopper, PPH40 powder pump, 6 m powder hose, pressure regulating valve and air distribution unit, standard hose connection accessories, and Nozzles & Spare Parts.
High-Performance Spray Gun Control Unit
Equipped with digital valve technology and PCC precise current control, the unit ensures stable airflow and pressure during coating. It also provides precise current adjustment below 10 µA, helping prevent powder overcharging and improve coating stability and quality.
The GC21 controller supports up to 20 programmable coating programs, and each parameter set can be saved automatically for fast recall in future production, helping improve working efficiency.
The system includes a built-in self-diagnosis function that automatically monitors operating status, identifies issues in time, and helps keep the equipment running reliably.
MG20 Manual Spray Gun
The MG20 manual spray gun features a built-in 100 kV high-efficiency voltage multiplication circuit that ensures stable output for outstanding coating performance. It is suitable for most standard powder types and can also handle powders that are traditionally difficult to charge. Its wear-resistant design and selected materials also help reduce maintenance costs.
The MG20 spray gun offers an ergonomic design and weighs only 510 g, combining light weight with excellent durability. Its unique spray angle and handle design help reduce operator fatigue during long working hours. The external remote control module allows parameters to be adjusted easily, and preset coating programs can be switched quickly by double-clicking the trigger, helping improve production efficiency.
PPH40 Powder Pump
The PPH40 powder pump features a plug-and-play design and is suitable for fast color change and quick cleaning. Its quick-connect powder hose structure makes disassembly and reconnection easier during cleaning. The venturi tube is made of high-quality non-stick material and is equipped with a quick connector for compressed air. It delivers stable and even powder feeding with excellent atomization, helping produce high-quality coatings. The maximum powder output can reach 520 g/min, depending on the actual configuration and powder type.
