Blower Unit

The Robox Lobe blower unit 

The Robox Lobe is able to reach up to 1,000 mbar(g) and vacuum up to 500 mbar(a) with a maximum capacity of 10,500 m³/h.

Unique design, best in class footprint, low noise, easy installation, easy to service and maintain access throughout the range. 

The integrated Robox blower unit design (sizes 3.0, 3.5, 4.0, 5.0) allows you to fit either a lobe 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.

Robox Lobe sizes 1.0 and 1.5 have been fully re‑engineered into a compact enclosure format, achieving footprint reductions of up to 20% without compromising performance—ideal for installations where every square inch matters.

Completing the portfolio, Robox Lobe 2.0 is the newest addition, featuring a purpose‑engineered noise‑enclosure frame with optimized fresh‑air conveyance to further enhance air‑end performance and long‑term reliability.

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.

One Package Two Technologies (Sizes 3.0, 3.5,4.0, 5.0)

Take advantage of the one solution for both lobe 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.

Small Footprint for Minimal Space Requirements (Sizes 1.0, 1.5)

The new additional frames — 1.0 and 1.5 — 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 blower dimensions, we've managed to reduce the overall footprint by an impressive 20%.

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.

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.

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 and 1.5 the 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.

NEW Frame 2.0 – Optimised Noise Enclosure and Performance

The Robox Lobe 2.0 introduces a newly developed noise‑enclosure frame with optimised fresh‑air conveyance, designed to deliver a clean and continuous supply of fresh process air directly to the air end. This enhanced airflow improves oxygen availability, stabilises operating conditions, and supports consistently high performance.

Designed to operate with a 55 kW motor, the RBS 65 for Frame 2.0 now reaches a maximum speed of 4,800 rpm, delivering up to 20 % higher flow within a reduced footprint. An optional airflow‑distribution module further improves internal cooling inside the acoustic enclosure, ensuring reliable operation even under demanding conditions.

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
