PRODUCTS OVERVIEW
The Sunrise Union 280kw 0.8MPa variable frequency screw air compressor is a compressed air solution specifically designed for EPS (expanded polystyrene) production lines. Featuring stable pressure output, durable running performance and remarkable energy saving effect, it perfectly meets pneumatic demands of bead expansion, material conveying, forming molding and cutting processing. Reliable continuous operation effectively stabilizes finished product quality and cuts long-term factory operating costs.
CORE FEATURES FOR EPS PRODUCTION LINE
- Permanent Magnet Variable Frequency Drive (PM-VFD): Adopts high-efficiency PM motor with 100% direct transmission (no motor bearings, zero transmission loss). Adjusts airflow 0–100% steplessly based on real-time EPS line demand (vs. 60–100% for standard inverters).
- 25–40% Energy Reduction: Cuts electricity bills drastically for 24/7 EPS production; saves 5–15% more energy than common VFD compressors.
- Stable 0.8MPa Pressure: Maintains pressure fluctuation ≤±0.2bar—critical for uniform EPS bead filling and molding, eliminating defective products from pressure drops.
- IP55 Dust-Proof Protection: Sealed casing prevents EPS dust and foam particles from entering internal components—ideal for dusty EPS workshop environments.
- Air-Cooled & High-Temperature Resistant: Operates reliably at 2–45°C ambient temperatures; optimized cooling system keeps discharge temperature ≤ ambient +15°C, avoiding overheating in continuous EPS production.
- 280kw Two-Stage Screw Air End: High-precision 5:6 asymmetric rotor profile; 30% longer service life than single-stage models, reducing maintenance frequency for non-stop EPS production.
- 58m³/min Large Air Capacity: Meets high-volume pneumatic demand of medium-to-large EPS factories (250–500kW installed capacity).
- Low Noise & Vibration: 82±2dB(A) noise level—quieter operation for worker comfort in EPS workshops.
- Intelligent Control System: Real-time monitoring of pressure, temperature, and runtime; multi-channel sensors ensure stable operation and quick fault diagnosis, minimizing unplanned downtime.
- ISO9001 & CE Certified: Strict quality control per international standards; all key components undergo 100% testing before delivery.
- Durable Construction: 304 stainless steel piping (corrosion-resistant, double service life vs. carbon steel); heavy-duty frame for long-term stability.
- Global After-Sales Support: 24/7 online technical support; 1-year warranty with fast spare parts supply for EPS production line continuity.

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.
