Blower Unit

The Robox Lobe blower unit

The Robox Lobe is able to reach up to 1,000 mbar(g) and vacuum capacity up to 500 mbar(a) with a maximum capacity of 10,500 m³/h. This performance makes it a versatile option among root blower and rotary lobe blower technologies.

Unique design, best in class footprint, low noise, easy installation, easy to service and maintain access throughout the range — all hallmarks of a premium positive displacement blower engineered by a trusted root blower manufacturer.

The new Robox blower unit design (sizes 3.0, 4.0, 5.0) allows you to fit either a lobe compressor or a screw airend into our engineered Robox enclosure. To accommodate this innovation, our teams performed a complete package redesign. You can call it thinking outside the box to create our best Robox yet — whether you're upgrading a roots blower or integrating a trilobe blower into your system.

In addition, the new Robox Lobe sizes 1.0 have been ingeniously redeveloped to boast footprints reduced by up to 20% without compromising on performance, making them the perfect choice for installations where every square inch counts — especially when selecting a tri lobe blower or root blower compressor for space-sensitive environments.

Unique Design, Best-in-class Footprint

Thanks to its exclusive features, the new Robox Lobe blower unit has compact dimensions with the possibility of side-by-side installation. It is easy to be installed with no requirements for ducting. The Robox Lobe blower’s compact dimensions will optimise your floor space usage — a key advantage for any rotary lobe blower setup.

One Package Two Technologies (Sizes 3.0, 4.0, 5.0)

Take advantage of the one solution for both lobe compressor and screw blower technologies. Whether revamping plants or your processes, you can review and compare each technology’s benefits for your operation before you commit to buy — ideal for users considering a positive displacement blower or trilobe blower upgrade.

Small Footprint for Minimal Space Requirements (Sizes 1.0)

The new additional frames — 1.0 — mark the smallest options within our lobe blower range. The distinctive configuration of the Robox Lobe package minimizes its footprint while concurrently preserving and enhancing performance. Depending on the lobe compressor dimensions, we've managed to reduce the overall footprint by an impressive 20% — a major win for compact root blower installations.

Low Noise

Low noise emissions are ensured by our new discharge and suction silencer design. In addition, canopy enhancements provide noise reduction thanks to special sound proofing material and upgraded panel thickness. In addition, the enclosure air inlet and outlet ducts are muzzled with a lined single-chamber plenum and lined bends — a feature appreciated in both roots blower and tri lobe blower systems.

Easy Installation

Save time and money thanks to the easy and flexible installation of the new Robox Lobe blower. Handle the Robox with ease utilizing the rigid base which has dedicated channels for forklifts. Place it on any even surface, with no need for special foundations. Thanks to its compact design, the Robox can be quickly and easily integrated into your existing system — whether you're installing a root blower compressor or a trilobe blower.

Accessible Service and Maintenance

All maintenance operations are easily performed from the front with the removal of the front panel or for bigger frames with the removal of side panels.

For frames 1.0 all the maintenance tasks, such as oil change, belt replacement, and air filter installation, can be effortlessly carried out by simply opening the rooftop and removing the front panel.

Additionally, air end overhaul and motor repositioning are conveniently achieved through unrestricted top and front access — simplifying service for any positive displacement pump configuration.

RBS - Oil-free Premium Airend

The Robox Lobe blower unit accommodates the RBS airend with three special profile lobes. Combined with a low pulse system, the lobes reduce the residual pressure pulsation of the conveyed gas to less than 2% of the operating pressure.

The RBS airend is equipped with splash-lubricated helical tooth synchronized gears for optimum rotor timing. High quality lobe profile rotors are controlled by three-dimensional instruments for top volumetric efficiency. Durable shaft design compliments the RBS’ reliable operation. The RBS airend is also oil-free certified, Class 0 certification, according to ISO 8573-1.

New Compact Suction Silencer

A newly designed Silencer is equipped with a dedicated filter cartridge for improved reliability and quicker maintenance. This minimises pressure drops. Noise reduction is provided by a new absorptive and reactive internal resonance chamber design.

Robust Discharge Silencer

A Reactive discharge silencer with increased thickness and spark arrester. This design prevents contamination of conveyed gas with sparks generated by the blower. Costly spark traps are no longer necessary.

Check Valve

The VRC check valve, engineered by Robuschi, is a proven and robust component designed to ensure reliable backflow prevention in demanding applications. Now strategically positioned within the device, it allows for quick access, making inspection and replacement faster and easier than ever. This thoughtful integration reduces downtime and simplifies routine maintenance, contributing to overall system efficiency.

Lubrication System

Robuschi’s dual splash lubrication system offers a compact, reliable, and maintenance-friendly solution for optimal performance. By eliminating the need for an external oil circuit, this system ensures consistent lubrication of critical components while minimizing complexity. Its simple yet effective design reduces maintenance requirements and enhances long-term reliability, making it ideal for continuous operation in industrial environments.

State-Of-The Art Noise Enclosure

The new powder coated enclosure ensures long lasting protection from corrosion, chemicals and the environment. In addition, the noise enclosure’s structure is equipped with tight-fitting frames for the doors and roof support. All the panels/doors are independent of each other and easily removable for inspection.

The new hood design inhibits noise emissions thanks to the enclosure’s air inlet and outlet ducts which are muzzled with a lined single-chamber plenum and lined bends. The closed baseplate is suitable for any type of floor guaranteeing proper noise reduction.

In addition the enclosure provides:

Side-by-side installation
Baseplate equipped with dedicated holes for easy access by forklift
Dedicated access for relief valve inspection and setting to reduce maintenance time
Access for routine maintenance operations from the front/rear/left/right side of the hood
Easy service with rear panel opening without the need to disconnect the process pipe
Electrical cable installation possible both from the top and bottom
