Variable frequency energy-saving

• No peak starting current, completely eliminating energy consumption during unloading
• Variable frequency starting current is low and has no impact on the power grid, which is particularly important for users in unstable areas of the power grid. Variable frequency control maintains the pressure band within 0.1 bar without the need for large gas storage tanks
• The pressure will not exceed the required value, and there is no energy waste
• The low starting torque of the motor has minimal impact on mechanical components, resulting in a longer service life of mechanical components (such as bearings). The torque is transmitted according to actual needs without wasting excess energy

Safe motor (power frequency unit)

• IP55 closed motor (F-class insulation, B-class temperature rise), effectively dustproof and water-resistant
• Can operate continuously and stably in an environment of 55 ℃/131 ℉

Permanent magnet motor (frequency converter unit)

• Compared with asynchronous motors, rare earth permanent magnet motors have a simpler structure
• Single, reliable operation, high power density, wide speed range, it is the ideal power choice for high-efficiency and energy-saving air compressors
• efficient
• Small size and light weight
• Low noise
• High starting torque
• Start without impact
• Wide speed range
• Configure efficient IE5, IP66 oil cooled permanent magnet variable frequency motor, achieving H-level insulation and B-level temperature rise.

Connection method of host motor

• GDK07-22 power frequency unit adopts belt connection
• GDK30-75 power frequency unit adopts gear direct connection
• GDK07-75 permanent magnet frequency converter unit adopts coaxial connection

Exquisite design, excellent performance, energy-saving and environmentally friendly, on-site micro oil screw permanent magnet variable frequency air compressor

Efficient Drive System

• The host is precision manufactured, sturdy and durable
• Coaxial connection of the host motor for higher transmission efficiency
• Without gearbox and coupling, the drive system structure is more stable

Oil cooled permanent magnet synchronous motor

• High quality permanent magnets are selected, which can withstand temperatures up to 180 ℃.
• The rotor has no excitation current, significantly improving efficiency.
• The starting current is small, reducing the impact on the power grid.
• Good performance indicators, with approximately constant efficiency and power factor.

Powerful frequency converter

• Built in frequency converter, unique air duct design, stable and reliable
• Adopting cutting-edge vector control technology, it has excellent low-frequency speed characteristics and dynamic response characteristics, and complete protection functions, which can achieve comprehensive protection from the frequency converter to the motor
• Safe lightning protection design with built-in lightning overcurrent protection device effectively enhances the self-protection capability of the frequency converter against induced lightning

The S series permanent magnet frequency converter brings you

Start smoothly

• No peak starting current
• Completely eliminating energy consumption during unloading and reducing the burden on electrical components
• The low starting current of frequency conversion has no impact on the power grid, which is particularly important for users in factories located in unstable areas of the power grid

Stable output pressure

• Variable frequency control maintains the pressure band within 0.1 bar without the need for a large gas storage tank
• The pressure will not exceed the required value, and there is no energy waste

No startup impact

• The low starting torque of the motor has minimal impact on mechanical components, resulting in longer service life of mechanical components such as bearings
• Transmit torque according to actual needs without wasting excess energy
