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

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.

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.

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.

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.

Typical Applications

• Wastewater Treatment Aeration: Provides stable oil-free air for biological tanks in municipal and industrial wastewater treatment, ensuring microbial activity and reducing aeration system energy consumption.
• Pneumatic Conveying: Ideal for closed conveying of powder materials (cement, grain, plastic pellets), with oil-free air preventing material contamination and pipeline blockages.
• Chemical & Light Industry: Supports chemical oxidation reactions, textile printing and dyeing, and paper bleaching, where oil-free air avoids catalyst poisoning or product quality issues.
• Food & Pharmaceutical: Used in food fermentation, packaging line purging, and pharmaceutical production processes, meeting industry hygiene standards with completely oil-free air.
