oil free pm vfd screw blower for pharmaceutical industries

The permanent magnet frequency conversion oil-free screw blower delivers superior performance, reduced energy consumption, and extended service life compared to traditional fans. It is widely adopted in multiple industries, thanks to its oil-free, air-cooled design and intelligent variable frequency operation.

Technical Parameters

• Power: 15kW
• Air volume: 10.5 m³/min
• Wind pressure: 0.8 bar
• Caliber: DN100
• Overall dimensions: 1580 × 700 × 1360 mm

Main Features

1. Constant pressure and frequency modulation modes: Supports constant pressure, frequency modulation, and user-adjustable modes, ensuring flexible and efficient airflow supply for various working conditions.
2. Full air-cooled, oil-free design: Oil-free compression guarantees clean airflow with no oil contamination. Air cooling keeps the blower running at low temperatures even under heavy loads, extending equipment life.
3. High-efficiency permanent magnet motor direct drive: Direct drive design increases operational efficiency and reduces energy losses, delivering stable, energy-saving performance.
4. Polymer anticorrosive material coating: Key components are coated for enhanced resistance to corrosion and oxidation, ensuring reliable operation even in harsh, humid, or corrosive environments.
5. Spiral carbon steel solid rotor: Robust rotor design improves wear resistance and strength, minimizes wear, and ensures stable, long-term airflow output.

Working Principle

The blower compresses air via a screw rotor in an oil-free state. The permanent magnet motor drives the screw, drawing air in, compressing and accelerating it, then discharging it steadily. Inverter technology automatically adjusts speed to match demand, ensuring stable airflow and energy efficiency. The oil-free design reduces contamination and maintenance needs compared to traditional fans and compressors.

Compared to Roots fans and piston compressors, this blower offers higher compression efficiency, lower noise, greater energy savings, and reduced maintenance costs. The permanent magnet motor and inverter system dynamically optimize power usage.
