Lightweight HVAC Air Compressor VFD Variable Frequency Drive 7.5kW

KY900E Series Low Power Air Compressor Dedicated Variable Frequency Drive

Low Power Air Compressor Dedicated Variable Frequency Drive is an energy-saving control device designed specifically for small air compressors, which achieves precise air supply and efficient energy saving by adjusting the motor speed.

FEATURES

• Low power adaptation: The power range covers 0.4kW to 7.5kW, suitable for small screw, vortex and other air compressors. Compact design, small size, light weight, easy to install in limited spaces.
• Efficient and energy-saving: Using vector control or V/f control technology, dynamically adjust the motor speed to match the actual gas demand. The energy-saving effect is significant, and compared with traditional power frequency drive, it can reduce energy consumption by 20% -40%.
• Precise control: Built in pressure closed-loop control system, with real-time feedback from pressure sensors, automatically adjusts motor speed to maintain a constant gas supply pressure. The speed adjustment range is wide, and it can achieve a speed ratio of 1:10 or higher.
• Comprehensive protection function: Integrate multiple protection mechanisms such as overload, overvoltage, undervoltage, overcurrent, and overheating to extend equipment lifespan. Support soft start/soft stop to reduce mechanical impact.

Product advantages

• Economic: Low initial investment cost, suitable for small and medium-sized enterprises or family workshops. Long term operation saves electricity costs and has a short investment return period (usually 1-2 years to recover costs).
• Stability: Adapt to a wide temperature range of -10 ℃ to 50 ℃, with dust and water resistance levels up to IP20/IP54. Strong anti-interference ability, compatible with various power grid conditions.
• Ease of Use: Supports communication protocols such as Modbus and CANopen, making it easy to integrate with upper computers or PLCs. Provide one click parameter setting function to simplify the debugging process.

Application

• Industrial sector: Pneumatic tools, spraying equipment, blowing systems, etc. for small manufacturing factories. Gas supply for precision instruments in laboratories, hospitals, and other places.
• Business field: Scenarios with low demand for compressed air, such as car repair shops, hair salons, dental clinics, etc.
• Home applications: Gas supply for home DIY tools such as nail guns and paint sprayers.
