Key Features & Benefits
1. Energy Efficiency & Cost Savings
- Two-stage compression reduces energy consumption by optimizing air delivery at different pressure levels.
- Variable frequency drive (VFD) technology adjusts motor speed to match air demand, eliminating energy waste from frequent loading/unloading cycles.
- Maintains consistent pressure (±1 bar), avoiding the 2-bar pressure gap common in traditional compressors, saving up to 45% in energy costs.
2. High Performance & Reliability
- Delivers 5 to 15 bar pressure with an exhaust volume of 6.8 to 15.9 m³/min, suitable for high-demand operations.
- Rotary screw technology ensures continuous operation without overheating or mechanical failure.
- Robust construction withstands harsh environments, including high temperatures and heavy-duty cycles.
3. Quiet & Low Maintenance
- Noise levels as low as 67 dB(A), creating a quieter workplace.
- Reduced oil consumption (only 52L capacity) and fewer moving parts minimize wear and maintenance needs.
- Durable components ensure long service life with minimal downtime.
4. Smart & Safe Operation
- Automated pressure control prevents overloading and ensures stable air supply.
- Advanced cooling system enhances thermal efficiency and prevents overheating.
- Compliance with industrial safety standards, reducing operational risks.

FAQ
Q1: Why choose a two-stage screw air compressor over a single-stage model?
A: Two-stage compression provides higher efficiency, as air is compressed in two phases, reducing energy loss and heat generation. This results in lower operating costs and extended equipment lifespan.
Q2: How does the VFD system save energy?
A: The variable frequency drive adjusts motor speed based on air demand, avoiding constant full-power operation. This reduces electricity consumption by up to 45% compared to fixed-speed compressors.
Q3: What maintenance does this compressor require?
A: Thanks to its durable screw mechanism and low oil consumption, maintenance is minimal. Regular oil changes, air filter cleaning, and periodic inspections ensure optimal performance.
Q4: Is this compressor suitable for 24/7 operation?
A: Yes, the rotary screw design is built for continuous duty, with efficient cooling systems to prevent overheating during prolonged use.
Q5: What industries benefit most from this compressor?
A: It’s ideal for manufacturing, automotive, food processing, pharmaceuticals, and construction, where reliable, high-pressure air supply is critical.
