Product Overview

The LobePro-500 High-Pressure Rotary Lobe Blower is an industrial-grade, heavy-duty solution engineered for continuous, reliable operation in demanding process environments. Designed specifically as a high-pressure lobe blower, it delivers exceptional volumetric efficiency and pressure stability up to 120 kPa — ideal for pneumatic conveying, wastewater aeration, vacuum packaging, and chemical dosing systems. Its robust cast-iron housing, precision-machined three-lobe rotors, and integrated water-cooled blower system ensure thermal stability and extended service life, even under sustained high-load conditions.

Certified for hazardous areas, the LobePro-500 meets ATEX Directive 2014/34/EU for ATEX blower applications in Zone 2 (gas) — making it suitable for installations where flammable vapors or dust may be present. With a powerful 55kW rotary blower motor and optimized gear train, it achieves a rated flow of 42 m³/min at full pressure, combining energy efficiency with low vibration and noise levels (<78 dB(A)). As the flagship model in the LobePro series, the LobePro-500 sets a new benchmark for performance, safety, and uptime in critical industrial processes.

Key Features

• Water-cooled bearings and oil sump for superior thermal management and longevity
• Three-lobe rotor design with helical timing gears for smooth, pulse-free airflow and reduced wear
• Integrated silencers, vibration-dampening mounts, and acoustic enclosure options
• IE3 premium-efficiency motor with IP55 protection and optional variable frequency drive (VFD) compatibility
• Modular construction for rapid maintenance and field-serviceable components

Technical Specifications

Applications

The LobePro-500 excels across diverse industrial sectors requiring precise, high-pressure air movement — including high-pressure lobe blower applications in cement & lime pneumatic conveying, food-grade vacuum transfer, biogas upgrading, pharmaceutical fluid bed drying, and municipal wastewater treatment plants. Its ATEX blower certification enables safe deployment in petrochemical refineries, paint spray booths, and solvent-based coating lines. As a water-cooled blower, it’s especially recommended for 24/7 operations in hot ambient environments or where oil degradation must be minimized. Backed by global service support and OEM spare parts availability, the 55kW rotary blower ensures maximum ROI and minimal lifecycle cost.
