250HP Oil-Injected Rotary Screw Compressor 8bar for Cement Plant
PRODUCTS OVERVIEW
The Sunrise Union 250hp 8Bar oil-injected screw compressor is a heavy-duty air source device specifically designed for cement plants. Its stable 8Bar pressure is suitable for the entire process of raw material transportation, cement mixing, and finished product packaging. The 250hp high power supports simultaneous air use in multiple workshops. Its dust-resistant and high-temperature-resistant design is suitable for the harsh working conditions of cement plants. Its continuous operation and low maintenance costs make it suitable for large-scale production. The compressor body features a dustproof and sealed structure and a high-temperature-resistant heat dissipation system, directly adapting to the high-dust and high-temperature production environments of cement plants. The screw rotor uses a wear-resistant coating, increasing the lifespan of core components by 30% and reducing downtime due to severe operating conditions.
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.
