The Robox Lobe Blower Unit delivers efficient pressure and vacuum performance in a compact, low-noise package. With capacities up to 10,500 m³/h, easy installation and accessible maintenance, it suits wastewater, pneumatic conveying and demanding industrial processes.
The Robox Lobe Blower Unit provides reliable positive-displacement airflow for industrial pressure and vacuum applications. Its engineered acoustic enclosure combines the Robuschi RBS tri-lobe airend, drive system, motor, silencers and essential package components in a compact arrangement.
The range delivers pressures up to 1,000 mbar(g), vacuum operation down to 500 mbar(a) and capacities up to 10,500 m³/h. Therefore, it can support both moderate-airflow installations and large industrial processes.
Compact Robox Lobe Blower Unit Design
Robuschi designed the package to minimise installation space while maintaining service access and airflow performance.
The re-engineered Robox Lobe sizes 1.0 and 1.5 reduce the package footprint by up to 20%. Consequently, they suit blower rooms, packaged plants and retrofit projects where available floor space is limited.
In addition, their rigid bases include dedicated forklift channels. Therefore, installers can position each unit on a suitable level surface without constructing specialised foundations.

Integrated Enclosure Platform
Robox frames 3.0, 3.5, 4.0 and 5.0 use a common engineered enclosure platform. Depending on the selected configuration, the enclosure can accommodate either a lobe airend or a Robox screw airend.
Consequently, facilities can use a consistent package concept across different airflow technologies. Moreover, the common enclosure approach can simplify plant layouts, access planning and future system upgrades.
New Robox Lobe Frame 2.0
The Robox Lobe 2.0 uses a purpose-designed acoustic enclosure with optimised fresh-air conveyance.
The improved airflow delivers a stable supply of fresh process air to the airend. As a result, it supports dependable performance and internal cooling.
Selected Frame 2.0 arrangements can also deliver increased flow from a reduced footprint. However, engineers must confirm performance against the exact airend, motor and operating pressure.
Oil-Free RBS Tri-Lobe Airend
The RBS airend uses three specially profiled lobes and a low-pulse system. Consequently, it limits residual pressure pulsation and supports smoother airflow.
Moreover, the compression chamber remains free from lubricating oil. Robuschi certifies the RBS airend as Class 0 according to ISO 8573-1.
Therefore, the blower suits applications where clean process air and contamination control are important.
Low Noise and Reduced Pulsation
Robuschi combines the tri-lobe airend with redesigned suction and discharge silencers.
The suction silencer uses absorptive and reactive sound-control principles. Meanwhile, the acoustic enclosure includes soundproofing material, thicker panels and lined air passages.
As a result, the Robox Lobe Blower Unit reduces mechanical noise and airflow pulsation without requiring a large external sound enclosure.
Easy Service and Maintenance
The package provides convenient access to major service components.
On smaller frames, technicians can perform tasks such as oil changes, belt replacement and filter maintenance through the front panel and enclosure roof. Larger frames also provide removable side panels.
In addition, technicians can access the airend and reposition the motor without dismantling the complete package. Therefore, routine servicing can require less downtime.
Durable Package Construction
The powder-coated enclosure protects internal components from corrosion, chemicals and environmental exposure.
Independent doors and panels allow quick inspection. Meanwhile, the rigid base supports secure installation and effective sound reduction.
The Robuschi VRC check valve also prevents reverse airflow. Its accessible position simplifies inspection and replacement.
Robox Connect 2.0 Controls
The optional Robox Connect 2.0 touchscreen provides real-time monitoring and control.
Available functions include:
Pressure and temperature monitoring
Maintenance interval management
Warning and alarm detection
Operating-data trends
Troubleshooting data logging

Remote monitoring capability
Consequently, operators can identify abnormal conditions earlier and improve maintenance planning.
Plug-and-Play Blower Package
A plug-and-play version can include a premium frequency converter, programmed electrical control panel and IP54 electrical cabinet.
Therefore, operators can adjust blower speed according to process demand. This approach can improve airflow regulation and reduce unnecessary energy use during lower-demand periods.
Communication options may include Modbus, Profibus-Profinet and CANopen, depending on the selected package.
Industrial Applications
The Robox Lobe Blower Unit may support:
Municipal wastewater aeration
Industrial wastewater treatment
Filter backwashing
Pneumatic conveying
Aquaculture aeration
Food and beverage processing
Chemical and pharmaceutical plants
Cement and lime production
General manufacturing
Pulp and paper processing
Mining applications
Power-generation processes
Vacuum and gas-transfer duties
However, the exact airend, motor and accessories must match the required airflow, pressure, vacuum and gas composition.
Choosing the Correct Robox Lobe Blower Unit
Correct selection depends on required capacity, discharge pressure or inlet vacuum, ambient conditions and operating duty.
Engineers should also confirm process-air temperature, altitude, electrical supply, noise limits, control requirements and installation space.
Therefore, specialists must select the package from model-specific performance data. Otherwise, an unsuitable blower may overheat, consume excessive power or fail to provide the required airflow.
