IE3 Premium Efficiency Motor Direct Driven Screw Air Compressor JF-50A-IE3
Product Overview
The JF-50A-IE3 is a high-performance direct driven rotary screw air compressor equipped with an IE3 premium efficiency motor, delivering up to 15% energy savings compared to standard IE2 motors. Designed for 24/7 industrial operation, this 37kw/50HP compressor provides reliable compressed air at 5.0-6.7 m³/min across 7-13 bar pressure range.
Key Features
- IE3 Premium Efficiency Motor: Compliant with IEC 60034-30-1 standards, reducing electricity consumption by 10-15% annually, lowering your total cost of ownership.
- Direct Drive 1:1 Coupling: Eliminates belt slippage and transmission losses. No belt replacement needed, ensuring stable power transmission and minimal maintenance.
- High-Efficiency Airend: Latest generation asymmetric rotor profile with 5:6 lobe ratio, delivering higher volumetric efficiency and lower specific power (kW/m³/min).
- Intelligent Microprocessor Controller: LCD display with real-time monitoring of pressure, temperature, running hours, and maintenance alerts. Auto start/stop and load/unload control.
- Advanced Air-Oil Separation: Three-stage separation system ensures outlet air oil content below 3 ppm, protecting downstream equipment.
- Low Noise Operation: Fully enclosed soundproof canopy with acoustic insulation, operating at 68±3 dB(A) – suitable for indoor installation near work areas.
- IP54 Protection: Dust and splash-proof enclosure, reliable operation in demanding industrial environments.
