Dual-Rating One-Machine Dual-Purpose Design
Integrates 30kW heavy constant torque and 37kW light variable torque modes. G-type fits screw air compressors for heavy-load startup; P-type matches fans and pumps. It reduces procurement and inventory costs with strong versatility.
Professional Air Compressor Vector Control
Preset exclusive compressor control program. 0.5Hz high torque ensures smooth heavy-load startup without stalling. Real-time speed adjustment realizes stable constant-pressure air supply, effectively solving pressure fluctuation and unstable operation of traditional fixed-frequency compressors.
20%-40% Industrial Energy Saving
Intelligently avoids no-load and light-load power waste. AVR automatic voltage stabilization ensures stable motor efficiency under grid fluctuation, greatly reducing long-term factory power consumption.
Heavy-Duty Anti-Trip Performance
Built-in high-precision PID controller realizes automatic constant pressure operation without external modules, improving air supply stability and reducing manual maintenance.
Complete Protection & Easy Integration
Full protection against over-current, over-voltage, under-temperature, phase loss and short circuit. Standard MODBUS-RTU communication supports seamless connection with PLC and HMI for intelligent industrial control.
The Z2400 series is widely deployed across diverse industrial sectors:
HVAC & Building Automation: Fans, pumps, compressors
Water & Wastewater Treatment: Pump regulation, flow control
Manufacturing & Machinery: Textile machinery, machine tools, conveyors
Mining & Heavy Industry: Conveyors, crushers, material handling

Industrial Automation: Main spindle motors, packaging equipment
Q1: What is the difference between G-type and P-type?
A: G-type (30kW) is constant torque mode for heavy-load screw compressors; P-type (37kW) is variable torque mode for light-load fans and pumps. Dual-rating design improves equipment matching flexibility.
Q2: Is this VFD dedicated for screw air compressors?
A: Yes. It is specially programmed for industrial screw compressors, supporting constant pressure operation, stable startup and intelligent energy saving, perfectly replacing original fixed-frequency and ordinary VFD drives.
Q3: What is the energy-saving effect?
A: According to actual air consumption conditions, the comprehensive energy-saving rate reaches 20%-40%, bringing obvious cost savings for long-running compressor equipment.
Q4: Can it work 24 hours continuously?
A: Yes. Adopting industrial-grade hardware and optimized heat dissipation design, it supports stable 24-hour heavy-duty continuous operation for industrial scenarios.
Q5: Does it support remote control?
A: Equipped with standard RS485 & MODBUS-RTU protocol, compatible with PLC, HMI and SCADA systems for remote monitoring and parameter adjustment.
Q6: What is your after-sales service?
A: 12-month factory warranty and lifelong free technical support. Free replacement and maintenance for non-artificial damage within the warranty period.
Q7: Do you support sample and customization?
A: Samples are available. We also support OEM/ODM customization such as logo printing and personalized parameter setting.
