Seize Air announces the global launch of its innovative Three-Stage Oil-Free Screw Air Compressor, engineered to deliver 100% CLASS 0 Certified oil-free air. This dry screw compressor sets a new standard in purity, efficiency, and intelligence for critical applications in industries like pharmaceutical, food and beverage, and electronics.
What is a Three-Stage Oil-Free Dry Screw Air Compressor?
An oil-free dry screw compressor operates without water, oil, or any other medium to seal the rotor gaps. The rotors do not contact each other and are sealed with a special coating, ensuring completely oil-free compressed air. The bearings and gears are lubricated via a separate oil system, which is completely isolated from the compression chamber to prevent any oil contamination.

Key Features & Technological Breakthroughs
1. 100% Oil-Free Air with CLASS 0 Certification
Our compressor is certified CLASS 0 Oil-Free by both TÜV Rheinland and Hefei General Machinery Research Institute. This makes it ideal for sensitive applications such as:
- Pharmaceutical manufacturing (GMP compliant)
- Food and beverage processing
- Electronics and semiconductor production
- Chemical and petrochemical industries

2. High-Efficiency Three-Stage Compression
The three-stage compression design reduces the compression ratio per stage, resulting in:
- Lower exhaust temperatures (around 110°C vs. 200°C in two-stage systems)
- Reduced internal leakage
- Higher volumetric efficiency
- Over 15% energy savings compared to conventional compressors
3. German-Engineered ACI Host Unit
We use custom-designed, high-performance ACI host units from Germany, featuring
·Stainless steel rotors with advanced anti-wear, anti-corrosion coating
·High-precision gears (AGMA 14 grade)
·SKF bearings for high temperature and corrosion resistance
·Integrated cooling jacket for temperature control and noise reduction

4. Intelligent and Energy-Saving Design
- IE4/IE5 high-efficiency motors (optional variable frequency drive)
- External cold air intake system improves efficiency by 2%
- Low-pressure loss cooling system and piping
- Variable frequency control (Invt inverter) for constant pressure and energy savings

5. Quiet and Reliable Operation
- Noise reduction of up to 7 dB through multi-layer acoustic design
- Anti-vibration and sealed enclosure with sound-absorbing materials
- Custom-designed silencers for reduced airflow noise
6. Smart IoT Connectivity

Real-time monitoring via PC, mobile, or onsite display
Remote warning and maintenance alerts
Multi-unit linkage and constant pressure/temperature control
