PRODUCTS OVERVIEW
FEATURES & BENEFITS
Feature 1: 100% Oil-free Compression Chamber
- Feature Detail: The compression chamber uses a dry-type twin-screw structure with no lubricating oil, grease, or other hydrocarbon-based fluids involved in the air compression process. It achieves air tightness and heat dissipation through precision rotor clearance control (≤0.05mm) and high-efficiency cooling systems, rather than oil.
- 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.
- 100% Oil-Free Air (ISO 8573-1 Class 0 Certified): Eliminates the risk of oil mist, oil vapor, or oil residue in compressed air—critical for industries like pharmaceuticals (avoids contaminating APIs or sterile packaging), food & beverage (meets FDA standards for edible product contact), and semiconductors (prevents oil-induced corrosion of sensitive chips).
- No Oil-Related Costs: You’ll never need to buy lubricating oil, replace oil filters, or dispose of waste oil. This cuts annual maintenance costs by 40-60% compared to oil-lubricated compressors.
- Simpler Compliance: Skip the hassle of regular oil contamination testing; the Class 0 certification helps you pass GMP, FDA, or ISO audits with minimal documentation.
Feature 2: IE4 Ultra-High-Efficiency Motor
- Feature Detail: Equipped with an IE4-rated premium motor (the highest efficiency class for industrial motors), with energy conversion efficiency ≥94.5%. The motor uses copper windings with low resistance, a high-precision bearing system, and a heat-dissipating aluminum housing to minimize energy loss during operation.
- 30% Lower Electricity Bills: For a 75kW model running 8,000 hours/year (typical industrial usage), an IE4 motor saves ~18,000 kWh annually (vs. an IE2 motor). At an average industrial electricity rate of $0.15/kWh, this translates to **$2,700 in annual savings**.
- Longer Motor Life: Reduced heat generation (≤80℃ operating temperature) and low bearing wear mean the motor lasts 8-10 years—twice as long as standard IE2 motors. This lowers replacement costs and avoids unplanned downtime.
- Eco-Friendly Operation: Lower energy consumption reduces your carbon footprint, helping your business meet sustainability goals (e.g., EU Emissions Trading System requirements or corporate ESG targets).
Feature 3: Optional Variable Frequency Drive (VFD)
- 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 1 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.
