EGV-132A-140 Oil-Free Permanent Magnet VFD Screw Blower

✨ Core Advantages
1. 100% Oil-Free Air Supply for Process Quality
With 0ppm residual oil content, the compression chamber has no contact with lubricating oil, ensuring completely oil-free compressed air. This eliminates contamination risks to process materials, microbial cultures, or clean environments, meeting strict purity requirements in food, pharmaceutical, and electronics industries.
2. Permanent Magnet VFD Direct Drive for Energy Savings
Equipped with a 132kW permanent magnet synchronous motor and direct drive transmission (eliminating belt losses), the variable frequency system automatically adjusts speed based on actual air demand. It delivers 20%-35% energy savings compared to traditional Roots blowers, significantly reducing long-term electricity costs.The motor features Class F insulation and IP55 protection, offering high temperature resistance, dust and water resistance for reliable performance in harsh conditions with extended service life.
3. Stable Operation with Low Maintenance
• Internal host temperature stays below 105°C, while discharge temperature is only 5-8°C above ambient, supported by efficient air cooling to prevent overheating shutdowns.
• Non-contact screw rotor design minimizes mechanical wear, extending maintenance intervals and reducing annual maintenance costs to less than 40% of conventional equipment.
4. PLC Intelligent Control for Easy Management
Standard PLC control enables real-time monitoring, parameter adjustment, and fault early warning via an intuitive HMI, lowering operational barriers. It also supports integration with industrial IoT for remote operation and data traceability.
5. Compact, Low-Noise Design for Versatile Installation
The screw compression delivers smooth airflow with minimal pressure pulsation, resulting in significantly lower noise than Roots blowers. With compact dimensions of 3100×1390×2070mm, it requires minimal floor space and no complex vibration damping foundation, adapting to diverse installation environments including workshops and wastewater treatment plants.
