Product Overview

The LobePro-50 Compact Rotary Lobe Blower is a high-efficiency, space-saving pneumatic solution engineered for continuous industrial duty. Designed for reliability in demanding environments, this 5.5kW lobe blower delivers a stable airflow of 3.2 m³/min at up to 60 kPa pressure — ideal for applications requiring precise, oil-free air movement. As part of our premium rotary lobe blowers series, the LobePro-50 combines robust cast iron housing with precision-machined three-lobe rotors to minimize pulsation, reduce noise, and extend service life. Its compact footprint makes it especially suited for retrofit installations or facilities with constrained mechanical room space.

IP54-rated protection ensures reliable operation in dusty, humid, or mildly corrosive industrial settings — from wastewater treatment plants to pneumatic conveying lines. The integrated cooling fins, heavy-duty bearings, and optimized gear train further enhance thermal stability and long-term performance without oil lubrication in the airstream.

Key Features

• Oil-free, dry air delivery — compliant with ISO 8573-1 Class 0 for critical processes
• Compact design with minimized floor space requirement (ideal for retrofits)
• Cast iron housing for superior vibration damping and structural rigidity
• Three-lobe rotor profile for smooth, low-pulsation airflow and reduced noise
• IP54 ingress protection for dust- and splash-resistant operation
• Integrated thermal overload protection and vibration-dampened mounting feet

Technical Specifications

Applications

This compact blower excels across diverse industrial sectors where clean, consistent airflow is essential. Common uses include wastewater aeration tanks, pneumatic conveying of powders and granules, vacuum packaging systems, biogas boosting, cement silo fluidization, and chemical process air injection. As a versatile 5.5kW lobe blower, the LobePro-50 serves as a dependable alternative to larger, less efficient units — particularly where space, energy efficiency, and maintenance simplicity are top priorities among B2B OEMs and plant engineers.
