PRODUCTS OVERVIEW
The 220hp two-stage compression variable frequency oil-injected screw compressor is a dedicated power equipment for mining processing. The two-stage compression + variable frequency technology saves more than 20% energy. The stable pressure of 8-10 Bar is suitable for core processes such as flotation and grinding. The IP55 motor is dust resistant and has a long maintenance cycle of 8000 hours, supporting continuous 24-hour production in mining plants and improving ore recovery rate. With a wide adjustable range of 8-10 Bar and pressure fluctuation ≤ ±0.02MPa, it precisely matches the needs of equipment such as flotation machines (8-9 Bar) and pneumatic grinding mills (9-10 Bar); with a large flow rate of 30-35 m³/min, a single unit can drive 3-5 core devices to operate simultaneously, improving the recovery rate of copper, silver and other ores by 5%-8%.
FEATURES & BENEFITS
Feature 1: Precision Oil-Injected Twin-Screw Air End
- Feature Detail: Adopts Japanese-origin screw rotors (5:6 rotor ratio) with 0.001mm machining accuracy; integrated oil separation system (99.9% oil removal rate) to ensure clean air output.
- User Benefit: Reduces rotor wear by 40% compared to ordinary screw air end– extends core component life to 8 years; 99.9% oil-free air avoids contamination of pneumatic tools/machines.
- Certification Support: Complies with ISO 8573-1 Class 1 (air quality standard) – attached test report available on request.
Feature 2: Energy-Saving Variable Frequency Drive (VFD) (Optional)
- Feature Detail: Optional VFD system adjusts motor speed based on air demand (0-100% capacity); 15kW-300kW motor with IE3 energy efficiency rating.
- User Benefit: Cuts electricity costs by 25-35% compared to fixed-speed models – for a 20 HP unit running 8 hours/day, saves ~$200/month on energy bills.
- Real Example: “A car parts factory in Germany switched to our VFD-equipped 160kw screw air compressors– their annual energy cost dropped from 12,000 to 8,000.”
Feature 3: Low Noise & Heat Dissipation
- Feature Detail: Silent motor (62-78 dB(A)), soundproof casing (10mm thick), and multi-stage cooler (aluminum alloy material) with auto-fan control.
- User Benefit: No need for separate soundproof rooms – suitable for indoor workshops; cooler maintains machine temperature below 85°C even in 45°C ambient conditions (avoids overheating shutdowns).
Feature 4: Smart Control & Easy Maintenance
- Feature Detail: 7-inch touchscreen PLC panel (supports customized Languages); real-time monitoring (air pressure, temperature, oil level) with auto-fault alerts; modular design for quick part replacement (air filter, oil filter, oil separator).
- User Benefit: Reduces maintenance time by 50% – oil change interval extended to 4,000 hours (vs. 2,000 hours for competitors); non-professionals can replace filters in 15 minutes.

FAQ
Q1: What’s the difference between your screw air compressor and piston air compressors?
A: Our screw compressor uses twin-screw rotors, which have higher efficiency (90% vs. 70% for piston), lower noise (60-75 dB vs. 80-90 dB), and longer service life (10 years vs. 5 years). It’s more suitable for continuous operation, while piston compressors are better for intermittent use (e.g., small workshops).
Q2: Do you provide a warranty for your screw air compressors?
A: Yes, The whole machine is guaranteed for one year,and can be extended to 5 years if customer special request. We also provide free maintenance guidance for life.
Q3: Can you ship to my country (e.g., USA/Canada/UK)?
A: Yes, we ship to worldwide. We can arrange sea freight, air freight, we also handle customs clearance documents (like commercial invoice, packing list, CE certificate) to ensure smooth delivery.
Q4: What’s the maintenance cost for Sunrise Union screw air compressors?
A: The annual maintenance cost is about US$150-300 (take 160kw as an example, depending on usage frequency). We provide maintenance kits (including oil filter, air filter, and lubricating oil) at factory price – changing the kit takes only 30 minutes, and no professional technician is needed.
