Robox Lobe

Smart Space Optimization
Designed with compactness in mind, the Robox Lobe makes the most of your available floor space. Its streamlined footprint allows for side-by-side placement, eliminating the need for ducting and simplifying layout planning.

Ultra-Compact Models
Available in the lineup, the 1.0 and 1.5 frames are the smallest, offering a footprint reduction of up to 20%. Ideal for installations where space is limited, these models deliver full-scale performance in a scaled-down package.

Quiet by Design
Noise reduction is built into every detail—from advanced silencer systems to sound-insulated panels and precision-engineered ducts. The result: a quieter working environment without sacrificing efficiency.

Plug-and-Play Installation
No special foundations, no complex setup. The Robox Lobe is built on a sturdy base with forklift channels for easy handling. It’s ready to go on any level surface, making integration into existing systems fast and hassle-free.

Maintenance Made Simple
Routine servicing is straightforward, with easy access from multiple sides. Smaller units feature a liftable roof and removable front panel, while larger models allow top and side access for more involved tasks. Everything from oil changes to belt replacements is designed for speed and convenience.

Premium Airend Performance
At the heart of the Robox Lobe is the RBS airend, featuring precision-engineered rotors and synchronized gears for optimal timing and efficiency. Certified oil-free (ISO 8573-1 Class 0), it ensures clean, reliable operation with minimal pulsation.

Advanced Silencing System
The newly developed suction silencer includes a built-in filter cartridge and a resonance chamber that reduces pressure drops and noise. The discharge silencer adds extra protection with a spark arrester and reinforced construction.

Integrated Check Valve
A custom-designed VRC check valve is built into the unit for quick inspection and easy replacement, enhancing reliability and reducing downtime.

Efficient Lubrication
The Robox Lobe uses a dual splash lubrication system that’s compact, effective, and low-maintenance - no external oil circuit required.

Durable Noise Enclosure
The powder-coated casing resists corrosion and environmental wear. Removable panels and tight-sealing frames make inspections and cable routing easy, while the enclosed baseplate supports installation on any surface.

At the core of the Robox Lobe lies the RBS airend - a precision-built tri-lobe rotary blower designed to deliver consistent, oil-free performance across a wide range of operating conditions. Manufactured by Robuschi, this airend combines advanced engineering with robust materials to ensure long-term reliability and minimal maintenance.

Precision Tri-Lobe Design
The RBS features dynamically balanced cast iron impellers with a tri-lobe configuration, rotating in opposite directions to deliver a steady flow of compressed air. This design minimizes pressure pulsations thanks to an integrated low-pulse system, improving system stability and reducing noise.

Oil-Free Operation
A pair of hardened, ground alloy steel timing gears ensures perfect synchronization between rotors, maintaining precise clearances and eliminating contact. The result: 100% oil-free air, certified to ISO 8573-1 Class 0 standards.

Built for Demanding Applications
With a rugged shaft design and long-life steel cage bearings rated for up to 20,000 hours, the RBS airend is built to withstand tough operating environments. Optional special coatings and seals are available for extreme duty applications.

Optimized for Performance
Every rotor is crafted using 3D measurement tools to ensure high volumetric efficiency. The splash-lubricated helical gears provide smooth, reliable timing, while the labyrinth seal and oil splash discs prevent contamination of the air stream.

Maintenance-Friendly Features
The RBS includes Pirex inspection windows for easy oil level checks and a compact lubrication system that eliminates the need for external oil circuits. These thoughtful design elements help reduce downtime and simplify routine servicing.
